保養指南

Brake Kit 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.
1. Before Ordering: Confirm the Full Vehicle Setup
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.
- Vehicle year, make, model, trim, market version, and chassis code if available
- Front or rear axle position
- Current brake rotor diameter, thickness, and caliper type if known
- Wheel diameter, width, offset, spoke shape, and inner barrel clearance
- Tire size and vehicle weight changes from armor, cargo, towing equipment, or track setup
- Driving use: daily street, towing, mountain driving, off-road, HPDE, rally, drift, track, or competition
- Whether the vehicle uses electronic parking brake, brake pad wear sensors, ABS / ESC systems, or special hydraulic routing
Wheel Clearance & Data Disclaimer: Technical fitment data applies strictly to rotor hats and mounting brackets—not wheel geometry. Wheel compatibility specs are provided for general reference only. Insufficient wheel clearance is not covered under warranty or data accuracy claims; if clearance is insufficient, wheel spacers must be added at the customer's discretion.
2. Understand What Type of Brake Kit You Are Ordering
Different TTSPORT brake kit series use different hardware layouts. Always confirm what the kit includes before purchase.
Direct-Mount Kits
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.
Two-Piece Rotor Kits
Use separate friction rings and rotor hats. Hat offset, ring bolt pattern, hardware style, and rotor direction must be matched correctly.
Racing / Custom Kits
May require bespoke brackets, rotor hats, brake lines, and engineering confirmation based on knuckle, hub, wheel, and competition use.
Off-Road / Heavy Vehicle Kits
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.
3. Confirm the Kit Specification Before Payment
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.
- Confirm vehicle application and axle position
- Confirm caliper model, piston count, and caliper color if applicable
- Confirm rotor diameter, rotor thickness, rotor construction, and left / right direction if applicable
- Confirm brake pad compound and intended use
- Confirm brake hose fitting type and routing compatibility
- Confirm whether caliper brackets, rotor hats, mounting hardware, wear sensors, or brake fluid are included
- Confirm minimum wheel diameter and spoke clearance requirement
- Confirm lead time, shipping method, and final invoice details
If any part is not listed in the final order or product page, do not assume it is included.
4. Before Installation: Inspect the Complete Kit
Inspect every component before installation. Do not modify, grind, drill, stretch, force, or space brake kit components to make them fit.
- Check all received parts against the order confirmation
- Inspect calipers, rotors, brackets, hats, hoses, pads, and hardware for shipping damage
- Confirm left / right caliper and rotor orientation where applicable
- Confirm rotor size, pad shape, hose fittings, bracket layout, and hardware style before installation
- Clean all mounting faces before assembly
- Confirm torque values, bedding procedure, fluid type, and bleeding procedure before starting work
- Use a qualified brake technician for installation
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.
5. Installation Checks
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.
Caliper Position
Verify caliper centering over the rotor and confirm even pad sweep across the friction surface.
Rotor Orientation
Confirm left / right rotor direction if the rotor uses directional vanes or directional face pattern.
Brake Hose Routing
Check brake hose length and routing at full steering lock and full suspension travel. No twisting, rubbing, stretching, or kinking.
Wheel Clearance
Check caliper-to-spoke and caliper-to-barrel clearance before road use. Wheel specs are for general estimation only—clearance issues are excluded from warranty/data claims and may require user-supplied wheel spacers.
Brake Fluid & Bleeding
Use the correct brake fluid type and bleed the system until pedal feel is firm and consistent.
Hardware Security
Torque all brake hardware to the specified value. Do not reuse damaged, unknown, stretched, or corroded safety-critical fasteners.
6. Bedding and First Heat Cycle
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.
- Follow the bedding procedure supplied with the exact pad and rotor compound
- Use moderate heat first unless the supplied procedure requires otherwise
- Do not start with emergency stops on a fresh pad / rotor setup
- Avoid holding the brake pedal while stopped on very hot pads and rotors
- Allow the brakes to cool after bedding
- After the first heat cycle, inspect pad contact, rotor surface, hose routing, hardware security, and fluid leaks
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.
7. Initial Break-In Period
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.
- Avoid repeated emergency stops unless required for safety
- Avoid hard track use until bedding and inspection are complete
- Monitor pedal feel, vibration, noise, smell, and rotor surface appearance
- Recheck for fluid leaks after the first road test
- Recheck torque where the kit instructions require post-heat-cycle inspection
- Contact TTSPORT if brake feel changes suddenly after installation
8. Routine Care and Inspection
Brake kits need regular inspection, especially after track use, off-road use, towing, mountain driving, winter salt exposure, or any brake service.
- Inspect brake pads for uneven wear, taper, glazing, cracking, or backing-plate damage
- Inspect rotors for cracks, heavy scoring, hot spots, minimum thickness, and runout
- Inspect calipers for fluid seepage, piston movement, dust boot damage, and uneven pad retraction
- Inspect brake hoses for rubbing, cuts, swelling, leaks, and fitting corrosion
- Inspect brackets, rotor hats, and mounting hardware for cracks, fretting, corrosion, or loosening
- Check brake fluid level, color, service age, and boiling-point suitability for your driving use
- Clean brake dust from wheels and calipers regularly, especially after wet, salty, or track conditions
9. Care by Use Case
Daily Street
Inspect pads, rotors, fluid level, and hose condition during normal service intervals. Prioritize quiet operation, smooth pedal feel, and even wear.
Towing & Mountain Roads
Check pad thickness, rotor surface condition, and fluid condition more often. Long descents create sustained heat even without track use.
Off-Road
Inspect for mud, sand, stone impact, hose abrasion, dust boot damage, and caliper contamination after trail use.
Track / HPDE
Inspect pads, rotors, fluid, and hardware before and after every event. Track heat shortens service intervals.
Drift / Competition
Check rear brake temperature, hydraulic handbrake behavior, pad wear, rotor cracking, and hardware condition frequently.
Carbon Ceramic
Use only compatible pads and approved bedding procedures. Inspect rotor surface condition carefully and avoid incompatible friction materials.
10. Stop Driving If You Notice These Symptoms
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.
- Soft pedal, sinking pedal, or sudden increase in pedal travel
- Brake fluid leak or wetness near a line, caliper, fitting, or master cylinder
- Grinding, scraping, severe vibration, or heavy brake judder
- Vehicle pulling strongly to one side under braking
- Burning smell after light driving
- Loose wheel, rotor, caliper, bracket, or hardware noise
- Brake warning light, ABS warning light, or traction-control fault after brake work
