Evolution Series · Front Axle · Platform-Adapted BBK
The TTSPORT Evolution EB8 is a front 8-piston big brake kit engineered for drivers who need more thermal capacity, stronger pedal authority, and more repeatable stopping behavior than a factory caliper can deliver. Two-piece forged aluminum calipers, staggered 28/32 mm pistons, and 380–405 mm two-piece rotors give you bite without harshness and confidence lap after lap, stop after stop.
Two-piece forged aluminum body with eight pistons (28 mm × 4 / 32 mm × 4) and 56.8 cm² of total piston area per caliper. Staggered sizing distributes clamp force evenly across the pad, reducing taper wear and giving a linear, modulated pedal.
Two-piece pistons with thermal insulators and dust boots slow heat transfer from pad backing to brake fluid. The result: less fade on long descents, track sessions, and repeated high-speed stops.
Internally vented Ø380 or Ø405 mm rotors with CNC-machined aluminum hats. Choose heat-treated high-carbon iron or carbon-ceramic composite to match your driving range and service expectations.
Large piston area combined with matched pad compounds delivers strong initial bite while keeping threshold braking controllable — important on street, canyon, and trackday duty cycles.

Pad compound is matched to rotor material. Iron/steel pads run only with iron rotors; carbon-ceramic pads run only with CCB rotors.
Two forged 8-piston front calipers.
Complete brake pad set for both front calipers.
Two two-piece rotors in your selected size and material.
Two CNC carbon-steel mounting brackets.
Two CNC aluminum hats.
Two PTFE/SUS304 stainless braided brake lines.
The EB8 is a platform-adapted big brake kit, not a universal one-bracket-fits-all assembly. Confirm these items against your vehicle and wheel before purchase.
Confirm you are running 19 in or larger wheels.
Measure spoke clearance before ordering. The EB8 requires at least 107 mm of minimum spoke clearance.
Confirm hub, knuckle, caliper bracket compatibility, brake line fitting type, and rotor diameter selection before placing the order.
Need a clearance check? Contact us with your vehicle, wheel spec, and intended use before placing the order.
The EB8 is platform-adapted with vehicle-specific brackets and brake line fittings. Contact us with your year, make, model, and wheel specification so we can verify caliper clearance, bracket availability, and rotor size before you order.
19-inch wheels or larger are required, with at least 107 mm of spoke clearance. Wheel offset and spoke geometry both matter — send us your wheel details if you are not sure.
380 mm suits most street and spirited driving builds. 405 mm adds swept area and thermal mass for heavier vehicles, frequent high-speed stops, or trackday use. Both run a 34 mm rotor thickness.
Iron/steel rotors are cost-effective, easy to service, and run pads with a 0–600 °C range and μ ≈ 0.38. Carbon-ceramic rotors are lighter, last longer under heavy use, and pair with pads rated 0–700 °C and μ ≈ 0.45. Pads must match rotor material.
Two forged 8-piston front calipers, two two-piece rotors in your selected size and material, matched brake pads, CNC aluminum hats, CNC carbon-steel mounting brackets, and PTFE/SUS304 stainless braided brake lines.
Yes. A proper bedding-in procedure is required to transfer pad material onto the rotor face and stabilize the friction couple. Skipping bed-in will cause uneven deposits, vibration, and reduced bite.
Send us your vehicle, wheel, and use case. We will confirm fitment, recommend rotor size and pad compound, and quote the right configuration.
Brake Kits · Fitment · Installation · Care Guide
A brake kit is not just a pair of larger calipers. Calipers, rotors, pads, hoses, brackets, rotor hats, mounting hardware, brake fluid, wheel clearance, and bedding procedure all work together as one system.
This guide explains how to confirm the right TTSPORT brake kit before ordering, what to check before installation, and how to care for the system after installation.
Do not order a brake kit by vehicle name alone. The correct kit depends on the vehicle, axle position, wheel package, driving use, and brake system layout.
Brake kits are application-specific. A visually similar kit can still have the wrong rotor offset, bracket geometry, hose fitting, caliper position, or wheel clearance requirement.
Different TTSPORT brake kit series use different hardware layouts. Always confirm what the kit includes before purchase.
Use direct-mount calipers and one-piece rotors where specified. These kits do not use rotor hats or caliper brackets unless the final product page clearly states otherwise.
Use separate friction rings and rotor hats. Hat offset, ring bolt pattern, hardware style, and rotor direction must be matched correctly.
May require bespoke brackets, rotor hats, brake lines, and engineering confirmation based on knuckle, hub, wheel, and competition use.
Require extra attention to wheel clearance, tire size, vehicle load, descent control, hose routing, and dust / water exposure.
Do not assume every brake kit includes the same parts. Package contents vary by product series, vehicle application, and final order configuration.
Before finalizing the order, review the kit specification carefully. Confirm the brake kit is matched to your vehicle and wheel setup, not only to the model name.
If any part is not listed in the final order or product page, do not assume it is included.
Inspect every component before installation. Do not modify, grind, drill, stretch, force, or space brake kit components to make them fit.
Safety: Brake kits affect braking force, hydraulic sealing, heat control, wheel clearance, and vehicle stability. Do not install the kit if fitment, torque, direction, clearance, or compatibility is unclear.
Correct installation is as important as the brake kit itself. A properly engineered kit can still perform poorly if installed with dirty mounting faces, incorrect torque, poor hose routing, or trapped air in the hydraulic system.
Verify caliper centering over the rotor and confirm even pad sweep across the friction surface.
Confirm left / right rotor direction if the rotor uses directional vanes or directional face pattern.
Check brake hose length and routing at full steering lock and full suspension travel. No twisting, rubbing, stretching, or kinking.
Check caliper-to-spoke and caliper-to-barrel clearance before road use. Wheel diameter alone is not enough.
Use the correct brake fluid type and bleed the system until pedal feel is firm and consistent.
Torque all brake hardware to the specified value. Do not reuse damaged, unknown, stretched, or corroded safety-critical fasteners.
Brake pads and rotors need a controlled bedding process before full performance is available. Bedding helps create an even transfer layer on the rotor surface, improving bite, pedal consistency, and vibration resistance.
Street pads, race pads, iron rotors, two-piece rotors, and carbon ceramic rotors may require different bedding procedures. Use the procedure supplied with the specific kit.
After installation and bedding, give the system a short break-in period before aggressive use. Pedal feel, pad contact, dust output, and noise may continue to settle after the first drives.
Brake kits need regular inspection, especially after track use, off-road use, towing, mountain driving, winter salt exposure, or any brake service.
Inspect pads, rotors, fluid level, and hose condition during normal service intervals. Prioritize quiet operation, smooth pedal feel, and even wear.
Check pad thickness, rotor surface condition, and fluid condition more often. Long descents create sustained heat even without track use.
Inspect for mud, sand, stone impact, hose abrasion, dust boot damage, and caliper contamination after trail use.
Inspect pads, rotors, fluid, and hardware before and after every event. Track heat shortens service intervals.
Check rear brake temperature, hydraulic handbrake behavior, pad wear, rotor cracking, and hardware condition frequently.
Use only compatible pads and approved bedding procedures. Inspect rotor surface condition carefully and avoid incompatible friction materials.
Do not continue driving if the brake system shows any of the following symptoms. Inspect the system or contact a qualified brake technician before using the vehicle again.
Send your vehicle details, brake kit series, wheel specs, driving use, photos, and any symptoms you notice. TTSPORT will help confirm fitment, installation checks, and the correct care path for your brake kit.
