Nissan Skyline GT-R R34 Brake Parts Catalog

The R34 GT-R came from the factory with Brembo brakes (front 4-piston, rear 2-piston), but even these legendary stoppers benefit from upgrades when pushing 400+ hp or hitting the track. This comprehensive catalog covers every brake upgrade option for your R34, from street-friendly pads to race-spec rotors.

Installation Difficulty & Time Estimates

Level 1: Brake Fluid Flush (DIY-Friendly)

Time: 1 hour Tools: Wrench set, clear tubing, drain bottle Difficulty: 1/5

Flush all 4 corners using gravity bleed or pressure bleeder. Start with furthest wheel from master cylinder (RR → LR → FR → FL).

---

Level 2: Brake Pad Replacement (Intermediate)

Time: 2 hours (all 4 corners) Tools: Socket set, C-clamp, brake cleaner Difficulty: 2/5

Remove wheels, compress caliper pistons, swap pads. Clean caliper slides. Bed-in procedure critical for performance pads.

---

Level 3: Rotor + Pad Replacement (Advanced)

Time: 3-4 hours (all 4 corners) Tools: Socket set, torque wrench, C-clamp, brake cleaner Difficulty: 3/5

Remove calipers, swap rotors, reinstall with new pads. Torque all hardware to spec. Bed-in procedure required.

---

Level 4: Brake Line Replacement + Fluid Flush (Advanced)

Time: 4-5 hours Tools: Flare nut wrenches, pressure bleeder, torque wrench Difficulty: 4/5

Remove all 4 rubber lines, install stainless lines, bleed entire system. Requires complete fluid flush. Check for leaks before driving.

---

Level 5: Brake Duct Installation (Professional Recommended)

Time: 6-8 hours Tools: Drill, hole saw, rivets, heat gun (for ducting) Difficulty: 5/5

Requires bumper removal, drilling air scoop holes, routing ducting through chassis. Professional install recommended unless experienced with body modifications.

---

Brake Pad Bedding Procedure (CRITICAL)

All performance brake pads require proper bedding to transfer pad material onto rotors. Skip this procedure and you'll experience noise, poor bite, and premature wear.

Bedding Steps:

1. Find safe location: Empty road, parking lot, or track
2. Warm-up: 5-10 easy stops from 40 mph (avoid coming to complete stop)
3. Bed-in sequence: 6-8 moderate stops from 60 mph to 20 mph (50-60% brake pressure)
4. Cool-down: Drive 5-10 minutes without braking (let rotors cool)
5. Final verification: 2-3 hard stops from 60 mph to 20 mph (80% brake pressure)

Signs of proper bedding:

• Consistent pedal feel
• No vibration or judder
• Even rotor coloring (gray film)
• Improved bite after cool-down

Common mistakes:

• ❌ Coming to complete stop during bedding (creates pad deposits)
• ❌ Insufficient cool-down (causes rotor warping)
• ❌ Too few bed-in cycles (incomplete material transfer)

Frequently Asked Questions

Q: Can I mix brake pad brands front/rear?

A: Yes, but not recommended. Different compounds have different friction coefficients, which can cause brake bias issues. Ideally, use the same compound front/rear, or at minimum the same brand (e.g., Project Mu RC09 front, Project Mu HC+ rear).

Q: Do I need to upgrade rotors if I'm only upgrading pads?

A: Not mandatory for street driving, but recommended for track use. Performance pads generate more heat than OEM, which blank rotors struggle to dissipate. At minimum, upgrade to slotted rotors when installing track pads (MX72, Z-Rated).

Q: How long do track pads last on the street?

A: Track pads (MX72, Z-Rated) wear faster on the street due to lower operating temps. Expect 15,000-20,000 miles for MX72 vs 25,000-35,000 for street/track pads (RC09). Race pads (Z-Rated) should not be used on the street.

Q: What's the difference between DOT 4 and DOT 5.1 brake fluid?

A: DOT 5.1 has a higher boiling point than DOT 4, but both are glycol-based. The R34 GT-R is designed for DOT 4 fluid. Most high-performance DOT 4 fluids (Motul RBF 660, Castrol SRF) exceed DOT 5.1 boiling points anyway. Stick with DOT 4.

Q: Do brake ducts make a big difference?

A: Yes, for track use. Brake ducts reduce rotor temps by 100-150°F, which prevents fade during consecutive sessions and extends pad/rotor life by 30-40%. For street driving, ducts provide minimal benefit. Only install if you're tracking the car 6+ times per year.

Q: Should I upgrade rear brakes?

A: The R34 GT-R has 70/30 brake bias (front does most of the work). Upgrade front brakes first (pads, rotors, lines, fluid). Only upgrade rear brakes if you've already maxed out the fronts and still want more stopping power. Most street/track cars only need front upgrades.

Q: Can I use race pads (Z-Rated) for street driving?

A: Absolutely not. Race pads require 400°C+ operating temps to function properly. Below this temperature, they offer less grip than OEM pads and will squeal constantly. Race pads are for dedicated track cars only.

---

Cross-Reference with Other R34 Upgrades

If you've installed engine upgrades: Turbocharged R34s making 400+ hp require at minimum Project Mu RC09 pads + slotted rotors. Stock brakes cannot safely handle the increased speed/weight transfer.

If you've installed suspension upgrades: Coilovers and sway bars improve turn-in grip, which increases braking zone speed. Pair suspension mods with brake upgrades to maintain safety margins.

If you're planning track days: Start with brake upgrades before power mods. Brakes are the most important safety system on track. A stock-power R34 with MX72 pads + SCR-PRO rotors is safer than a 500hp R34 on stock brakes.
