Direct-Mount Series · Rear Axle · Single-Piston Disc Conversion
The TTSPORT Suzuki Jimny Rear Disc Brake Kit is a Direct-Mount Series rear-axle conversion engineered for Jimny JB23 / JB33 / JB43 / JB53, JB64W / JB74W, and JC74W applications. It uses a cast single-piston rear caliper, Ø274 mm × 9 mm one-piece solid rear rotors, stainless-steel braided brake lines, and vehicle-specific fittings.
This rear disc setup is built for owners who want more predictable rear brake response, cleaner service access, and better trail-side inspection than enclosed drum hardware. Because rear brake conversions interact with parking-brake operation and hydraulic balance, chassis code, parking-brake layout, rear hub configuration, and brake-line fittings must be confirmed before ordering.
Open rear rotors make pad inspection, cleaning, and service easier than enclosed drum hardware after mud, water, and trail debris.
One 34 mm rear piston targets controlled rear brake torque without overpowering the rear axle.
One-piece solid rear rotor with fixed mounting, directional left/right design, and blank rotor face pattern.
Three-layer PTFE / SUS304 / PVC brake lines with application-specific caliper-side and chassis-side fittings.
Designed for 15 in or larger wheels with at least 56 mm minimum inner-spoke clearance.
Rear parking-brake configuration varies by chassis and market. Confirm the correct solution before installation.

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.
