Understanding the Factory R35 Brembo Brake System

The Nissan GT-R R35 arrives with a factory-installed Brembo braking system that represents one of the finest OEM setups ever fitted to a production automobile. This foundational knowledge is essential for selecting compatible aftermarket components.

Factory Brake Specifications

Front Brakes: 390mm diameter, 4-piston Brembo calipers with OEM compound pads Rear Brakes: 380mm diameter, 4-piston Brembo calipers with OEM compound pads Brake Fluid: DOT 5.1 (ABS-integrated system with traction control) Weight Distribution: 1,740kg total (approximately 60/40 front-to-rear under braking)

The massive rotor diameters—particularly the 390mm front—were engineered to absorb the sustained thermal energy generated by a 1,100+ horsepower platform accelerating from 0-320 km/h repeatedly. Factory calipers are competent high-temperature units, but they employ cast construction that begins to limit performance in professional race applications exceeding 5-10 lapping sessions without cooldown.

Why Upgrade from Factory Brakes?

While Brembo's OEM application is excellent for production tolerances, several limitations emerge during extended circuit work:

• Pad Compound Limitations: Factory compound targets 90% road use, 10% performance driving. Brake fade accelerates after 3-4 aggressive lapping sessions.
• Thermal Capacity: Continuous lap work pushes brake fluid temperature toward boiling point (especially ABS-integrated fluid). OEM calipers lack sufficient cooling channels.
• Modulation Consistency: Factory pads exhibit temperature-dependent friction curve changes. Track-optimized compounds maintain predictable modulation across 150-400°C rotor surface temperatures.
• Corrosion Resistance: Long-term storage and humid JDM environments (coastal areas, monsoon season) cause pitting on OEM rotors without protective coatings.

The Endless Compound Ladder: Choosing Your R35 Brake Pad

Endless, the legendary Japanese brake manufacturer, offers a structured compound hierarchy designed specifically for GT-R applications. This ladder approach allows R35 owners to select exactly the right compound for their intended use case.

MX72: The Sweet Spot for Street + Track Enthusiasts

Application: 80% road / 20% track use Operating Temperature Range: 0-350°C Bite Characteristics: Progressive, forgiving Dust Level: Moderate Noise Profile: Quiet

The Endless MX72 compound represents the gateway into serious brake performance. If you drive your GT-R regularly on Japanese highways (Haneda connections, coastal runs) and occasional weekend lapping, MX72 is the statistically recommended starting point.

Real-world Performance: MX72 delivers superior modulation compared to factory pads without sacrificing street manners. Drivers report immediate feedback improvement and reduced brake lag—particularly valuable in Akina-style mountain driving where precise braking point definition matters. Why R35 Owners Choose MX72:

• Linear friction curve prevents sudden bite transitions at high speeds
• Maintains performance across varying ambient temperatures (Japanese winter 5°C to summer 40°C)
• Compatible with factory Brembo calipers (no modification required)
• Extended rotor lifespan compared to aggressive compounds
• Excellent for spirited driving without commitment to full race compounds

MX72 Plus: Enhanced Thermal Stability

Application: 70% road / 30% track use Operating Temperature Range: 0-380°C Bite Characteristics: Aggressive, predictable Dust Level: Moderate-High Noise Profile: Slightly elevated

The MX72 Plus represents the logical progression for R35 owners experiencing MX72 limitations during extended lapping sessions. This compound addresses two critical weaknesses: fade resistance under sustained braking and superior bite at elevated temperatures.

Thermal Superiority: MX72 Plus maintains friction coefficient stability above 300°C, where MX72 begins exhibiting slight fade. During a 30-minute Tsukuba session, MX72 Plus drivers report consistent turn-in bite on lap 1 and lap 15—a massive advantage in competitive time attack environments. Dust Trade-off: Higher friction coefficient naturally produces more brake dust. Plan for monthly wheel cleaning during intensive track seasons. The dust is non-corrosive and easily removed with standard wheel cleaners.

CC-Rg: Maximum Road Friction

Application: 100% track-focused, occasional street Operating Temperature Range: 80-380°C Bite Characteristics: Maximum initial grip Dust Level: Moderate Noise Profile: Quiet

The Endless CC-Rg compound exists in the specialized realm of ultra-high-friction race compounds. It delivers the absolute maximum brake force at moderate temperatures—a critical advantage for track days where cold braking (under 100°C) happens frequently during early-session sighting laps.

JDM Circuit Advantage: CC-Rg's unique friction architecture excels in Japanese circuit racing where single-lap pace matters (qualifying sessions, one-off time attack events). Competing at Suzuka or Fuji demands maximum braking force on the critical Dunlop Curve and main straightaway braking zones. Limitation: Below 80°C, CC-Rg performs below MX72 Plus—unsuitable for street applications. Excessive dust production requires frequent rotor resurfacing on pro race applications.

CC-R: The Race Compound Standard

Application: 100% circuit racing, specialized time attack Operating Temperature Range: 100-450°C Bite Characteristics: Extreme aggression, narrow friction window Dust Level: High Noise Profile: Moderate

Endless CC-R represents the equipment of professional GT-R race teams competing in Japan's Super GT and time attack series. This compound operates in an extreme temperature window—above 100°C minimum to achieve rated performance, tolerating temperatures approaching 450°C during maximum deceleration zones.

Professional Context: Only specified for R35s running Endless Mono 6 or Racing MONO 6r calipers with advanced cooling systems. Factory Brembo calipers lack sufficient thermal management for safe CC-R operation.

ME20 & MA45B: Competition Extremes

ME20 Application: Low-temperature circuit racing (spring/autumn sessions at Tsukuba) MA45B Application: High-downforce racing vehicles, maximum deceleration demands

These specialized compounds address niche use cases rarely relevant to road-going GT-R owners. Mention is included for comprehensive understanding, but standard recommendations remain within the MX72 → MX72 Plus → CC-Rg hierarchy.

Endless Rotor Technology for R35 Applications

Beyond pad compound selection, rotor design dramatically influences brake feel, heat dissipation, and rotor lifespan—three factors critical to sustained circuit performance.

Endless Curving Rotor Architecture

Standard Configuration: Straight radial slots running from rotor hub to outer diameter Endless Curving Design: Curved slots that spiral progressively across rotor face

The Endless Curving Rotor technology represents a significant evolution from traditional slotted designs. Curved slots optimize several mechanical phenomena:

• Gas Escape Efficiency: As brake pads contact rotor surface, extreme pressures generate decomposing friction material gases. Straight slots allow gas pockets to form, reducing pad-rotor contact pressure. Curving slots force gas outward in spiral pattern, maintaining consistent contact pressure throughout brake application.
• Pad Compound Retention: Curved architecture prevents aggressive pad material stripping that occurs with sharp-edged straight slots. R35 pads maintain consistent thickness wear across the pad face—improving braking consistency lap after lap.
• Thermal Distribution: Spiral slot pattern distributes heat more uniformly across rotor face, preventing hot spots that accelerate rotor warping.

R35-Specific Rotor Sizing

Given the R35's 1,740kg weight and 390mm/380mm factory rotor diameters, aftermarket rotor selection should maintain or exceed these dimensions:

• Front Recommendation: 390mm diameter, 32-34mm thickness (factory = 30mm)
• Rear Recommendation: 380mm diameter, 28-30mm thickness (factory = 28mm)

Increased thickness in front rotors provides superior thermal mass without requiring mechanical caliper modifications. Extra millimeters allow for more aggressive use cases (20+ lap sessions) and extended rotor replacement intervals.

R35 Big Brake Kit (BBK) Upgrades: The Mono 6 Evolution

For R35 owners committing to serious circuit racing or competitive time attack, stepping beyond pad and rotor upgrades toward dedicated big brake kits unlocks performance plateaus unavailable within factory caliper constraints.

Endless Mono 6 Caliper System

Caliper Type: Forged aluminum, 6-piston monoblock design Rotor Compatibility: 330mm (front), 370mm (rear) factory-optimized sizing Brake Modulation: 6 independently-pressured pistons provide granular stopping force control Weight: Approximately 2kg lighter than factory Brembo calipers (per corner) Thermal Capacity: 3x greater cooling surface area relative to factory design

The Endless Mono 6 represents the ideal big brake kit for R35 owners seeking maximum performance without excessive size or complexity. Six-piston architecture delivers the braking feel of extreme stopping force while maintaining the progressive modulation essential for trail-braking through Japanese circuit corners.

Why Mono 6 Over Racing MONO 6r?: The standard Mono 6 provides 95% of Racing MONO 6r performance at significantly lower cost. For most R35 owners (even dedicated time attack competitors), Mono 6 represents the optimal efficiency frontier. Installation Considerations: Mono 6 retrofit requires:

• Custom brake line fabrication (Endless provides engineering drawings)
• Master cylinder pressure adjustment (professional tuning recommended)
• Wheel clearance verification (most factory / OEM+1 wheel fitments compatible)
• DOT 5.1 fluid system flush and refill

Endless Racing MONO 6r: Professional Grade

Caliper Type: Ultra-light forged aluminum, 6-piston monoblock with extreme cooling fins Weight: 1.2kg lighter than standard Mono 6 Rotor Compatibility: 330mm (front), 370mm (rear) with carbon rotor options Thermal Capacity: Ultimate heat dissipation for multi-day racing events Cost: 40-50% premium over standard Mono 6

The Racing MONO 6r exists for professional race teams and extreme enthusiasts. Unless you're competing in official Super GT series or high-level time attack championships, the marginal gains don't justify the cost premium.

Alternative BBK Options: R Attack and SET Motorsport

R Attack RA520/RA620 Calipers: Budget-conscious option featuring Italian engineering and competitive pricing. RA520 fits factory R35 rotor diameter without modification; RA620 enables rotor upsizing to 350mm (front) configuration. R Attack Pad Options:

• MQ300: Street-focused, lower dust
• MQ460: Aggressive circuit compound
• DTC-60: Race-specific extreme compound

SET Motorsport TX6 / RX6 Calipers: Mid-range alternative offering monoblock aluminum construction with competitive thermal performance. Popular in Japanese time attack series for cost-to-performance ratio.

Circuit-Specific Brake Setup Recommendations

Japanese circuits demand different braking characteristics based on layout, elevation changes, and corner sequencing. Tailoring your R35 brake setup to specific venues unlocks lap time advantages.

Tsukuba Circuit (1,2 km, Japanese Time Attack Favorite)

Brake Requirements: Short lap, high-frequency braking, moderate thermal load Pad Recommendation: Endless CC-Rg or MX72 Plus Rationale: Tsukuba's short lap (100 seconds typical) creates frequent braking events without sustained high-speed straights. CC-Rg's superior low-temperature friction provides consistent bite in early session cold conditions and early laps when rotors remain below 150°C. Caliper Setup: Factory Brembo or Endless Mono 6 (both adequate for Tsukuba's moderate thermal demands)

Suzuka International Raceway (5.8 km, Extreme Demands)

Brake Requirements: Maximum sustained heat, extreme confidence required at 300 km/h zones Pad Recommendation: Endless CC-R or ME20 (paired with Mono 6 calipers mandatory) Rationale: Suzuka's 130R corner and Spoon Curve demand absolute brake confidence at near-maximum velocity. 130R braking zone specifically requires consistent friction coefficients at 350°C+ rotor temperatures—CC-R's narrow friction window excels in this application. Cooldown Intervals: 5-10 minute cooldowns recommended between 4+ lap sessions to manage brake fluid temperature (ABS integration limits safe fluid temperature to 150°C maximum).

Fuji Speedway (4.56 km, Elevation-Heavy Layout)

Brake Requirements: High downforce braking (low elevation), sustained heat during straights Pad Recommendation: Endless MX72 Plus (primary recommendation) or CC-Rg Rationale: Fuji's 1st corner braking zone drops significant elevation (75m descent), generating extreme brake pressures during initial deceleration. MX72 Plus handles this scenario better than aggressive CC-R compound—extreme bite isn't necessary, consistency is paramount. Setup Advantage: Front brake bias can increase 1-2% compared to Tsukuba. Fuji's long straights (Dunlop Straight) provide extended cooling periods between braking zones.

Critical R35 Brake Bedding Procedure

Improper brake bedding causes catastrophic performance issues: glazed rotors, inconsistent friction, premature pad wear. The R35's 1,740kg mass and powerful stopping force demand disciplined break-in protocols.

Week 1: Conservative Bedding (50-80 km)

Objective: Establish initial pad-rotor interface transfer layer Brake Pressure: Moderate (40-60% max braking force) Speed Ranges: 30-80 km/h Rest Intervals: 10-minute cooldowns every 15 km Temperature Target: Maintain rotor surface below 150°C

Drive conservatively, gradually increasing braking force. Avoid aggressive stopping—this phase builds the crucial resin transfer layer that defines final brake performance.

Week 2: Moderate Intensity (80-150 km)

Objective: Deepen pad-rotor bond, verify consistent friction Brake Pressure: Moderate-Aggressive (60-85% max braking force) Speed Ranges: 60-120 km/h Rest Intervals: 10-minute cooldowns every 20 km Temperature Target: Rotor surface 200-300°C acceptable

Increase braking intensity gradually. Perform 10-15 moderate-force stops from highway speed, followed by cooldown period. Listen for squealing or chattering—indicators of improper transfer layer formation.

Week 3: Performance Confirmation (150-250 km)

Objective: Validate full friction potential, confirm rotor flatness Brake Pressure: Aggressive (85-100% max braking force) Speed Ranges: 100-150 km/h Rest Intervals: 15-minute cooldowns every 30 km Temperature Target: Rotor surface 300-400°C acceptable

Perform maximum-force stops from highway speeds. Braking distance should stabilize—if pad-rotor interface remains incomplete, distance will shorten gradually throughout this phase. Inconsistent performance indicates improper bedding; restart protocol.

Week 4: Track Validation (250+ km)

Objective: Final confirmation on controlled circuit environment Setting: Professional track day, first 3-5 laps sighting at 70% pace Performance Target: Consistent lap times, fade-free braking, smooth modulation

Track validation confirms bedding success. If lap-1 braking differs significantly from lap-5, bedding remains incomplete. Return to conservative street driving for an additional 100 km before attempting serious lapping.

Critical Point: Rushing this process costs money and frustration. Properly bedded Endless MX72 Plus pads deliver 30,000+ km lifespan; improperly bedded pads fail catastrophically at 10,000 km.

Compatibility Matrix: Caliper and Pad Options

Not all pads suit all calipers. This matrix prevents costly mismatches:

Key Compatibility Rules:

• CC-R compound requires monoblock aluminum calipers (Mono 6 / Racing MONO 6r / RA620)
• R35's factory caliper cooling insufficient for CC-R sustained use
• All pads compatible with factory 390/380mm rotor diameters
• Rotor upsizing (RA620 enables 350mm front) requires caliper-specific verification

---

Maintenance and Long-Term Care

Brake system longevity depends on consistent maintenance protocols specific to high-performance driving:

Monthly Inspection (Critical for Circuit Drivers)

• Rotor thickness measurement (via dial calipers at 4 circumferential points)
• Pad wear indicator inspection (visual thickness assessment)
• Brake fluid color check (should be clear amber; dark brown indicates moisture contamination)
• Visual caliper inspection for seal leakage or corrosion
• Wheel cleanliness (brake dust accumulation indicates excessive wear)

Quarterly Service (Recommended for Track Users)

• Professional rotor resurfacing (removes glazing, restores flatness)
• Brake fluid flush and replacement (prevents boiling point degradation)
• Pad thickness measurement and replacement at 2mm remaining thickness
• Caliper seal inspection and lubrication with appropriate brake grease

Annual Deep Service (Mandatory for Professional Competitors)

• Complete system pressure bleeding and air evacuation
• Rotor replacement (versus resurfacing) if thickness exceeds legal minimums
• Pad compound re-evaluation based on track usage patterns
• Master cylinder seal inspection
• Brake line inspection for micro-cracks or bulging

Storage Protocol (Critical for Seasonal Storage)

If your R35 enters winter storage (common in northern Japan):

• Before Storage: Drive gently for 30 minutes to elevate brake temperature, then perform moderate braking 5-6 times to establish protective rotor oxide layer
• During Storage: Cover wheels to prevent moisture accumulation; avoid prolonged brake application (parking brake use for extended periods causes pad deterioration)
• Before Season Restart: Allow 200 km gentle break-in before serious driving; systems degrade during dormancy
