The TTSPORT TR65 Water-Cooling Front 6-Piston Big Brake Kit is built for sustained circuit abuse — endurance stints, time attack, and back-to-back hot laps where pad temperature, fluid temperature, and brake balance decide the result. A monoblock forged caliper with staggered 27 / 32 / 38 mm pistons works with a two-piece Ø355 or Ø370 mm vented rotor and integrated water-cooling routing to keep the friction window stable lap after lap.
The TR65 Water-Cooling system is engineered for circuit, time attack, and endurance use where normal front caliper heat management can become the limiting factor. Water-cooling routing, a monoblock forged aluminum body, 50.10 cm² piston area, 36 mm-thick two-piece rotors, and racing pad options work together to keep pedal feel, friction behavior, and service life more consistent under sustained heat.
Integrated water-cooling routing pulls heat off the caliper body so pedal feel does not drift between stints.
27 / 32 / 38 mm pistons distribute clamp load across the pad to even out wear and reduce taper at race temperatures.
One-piece forged 6061-grade aluminum housing for high stiffness, low flex, and consistent pedal travel under load.
Ø355 or Ø370 mm × 36 mm two-piece rotors with fixed or floating mounting depending on rotor size and chassis.
Standard 0–600 °C / μ 0.38 pads, or racing 0–750 °C / μ 0.45 pads for sustained pro-am use.
Replaceable rotor rings, rebuildable seals, radial-mount brackets, vehicle-specific braided lines, and required bedding workflow.

Every TR65 Water-Cooling front circuit racing system is engineered around the vehicle’s front knuckle, hub location, rotor hat offset, wheel barrel, spoke clearance, brake line routing, water-cooling line routing, front brake bias target, rear brake pairing, suspension package, and competition class. The goal is not a generic universal fit; the goal is a water-cooled front brake package that works with your chassis geometry and keeps friction behavior stable across sustained circuit heat.
We review the chassis, front suspension and knuckle setup, motorsport use, target front brake behavior, wheel package, tire compound, rear brake pairing, cooling-line packaging, competition class, and whether the car uses OEM or custom front uprights.
For OEM knuckles, provide chassis, year, wheel specs, suspension layout, target use, and available cooling-line routing space. For custom uprights, motorsport hub conversions, or non-OE rotor offsets, provide CAD files, technical drawings, hub-face data, rotor mounting dimensions, water-cooling routing constraints, or accurate bracket mounting-point measurements.
TTSPORT confirms rotor diameter, vehicle-specific caliper bracket geometry, rotor hat offset, wheel clearance, brake line fittings, cooling-line routing, pad compound, and pad-to-rotor alignment before production begins.
If you are unsure whether your wheel, front knuckle, hub geometry, rotor offset, cooling-line routing, rear brake pairing, or competition layout is suitable, Contact us before ordering so the engineering team can review the build details.
This kit is engineered for circuit, time attack, and endurance use. Racing pistons run without dust boots and use racing compounds. It can be driven on the road for transit, but it is not optimized for daily use or cold-bite scenarios.
Choose Ø355 × 36 mm for lighter cars and sprint sessions where rotating mass matters. Choose Ø370 × 36 mm for heavier chassis, endurance stints, or high-downforce setups where thermal capacity is the priority.
Standard Steel uses heat-treated high-carbon iron suited to club racing and HPDE. Racing Steel uses a racing-grade heat treatment paired with the 0–750 °C / μ 0.45 pad for higher sustained temperatures and tighter μ stability.
18-inch wheels or larger are required. Final clearance depends on wheel face design, offset, spoke profile, rotor diameter, bracket package, and water-cooling line routing. Send wheel specs and TTSPORT will verify before shipping.
Yes. Bedding-in is required before track use to transfer pad material to the rotor face evenly. The procedure ships with the kit. Skipping it will compromise pad life and friction stability.
Yes. TTSPORT engineers radial brackets, hat offsets, cooling-line routing, and braided lines to the vehicle. Contact the team with chassis, year, wheel spec, suspension layout, and intended use so fitment can be confirmed before production.
Our race engineering desk handles fitment confirmation, pad selection, rotor sizing, bracket geometry, rotor hat offset, brake line routing, and water-cooling routing for your chassis.
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.
