xElectronic Parking Brake Series · Rear Axle · Calipers + Pads Only
EPB Rear Single-Piston Calipers
The TTSPORT EPB Calipers are rear single-piston electronic parking brake calipers built for custom brake conversions that must retain electronic parking-brake function. They are intended for fabricators and installers integrating a dedicated EPB caliper alongside a separate performance hydraulic rear brake setup.
Electronic Parking Brake Series

Single-Piston
Dust-Boot Piston
Cast Construction
18 in Wheel Min.
Calipers + Pads Only
Why Builders Choose the EPB Calipers
Many modern platforms rely on the OE rear caliper to actuate the electronic parking brake. When the rear brake system is converted to a separate multi-piston performance caliper with no EPB motor, parking-brake function can be lost. These standalone EPB calipers are designed to restore electronic parking-brake operation without forcing the primary hydraulic performance caliper to carry EPB hardware.
Separate from the Main Brake Caliper
Intended to work alongside a separate hydraulic performance rear caliper, not replace the full rear braking system by itself.
Brake Pads Included
Supplied with brake pads for the included EPB calipers, reducing one fitment variable during rear-corner planning.
OE EPB Logic Compatibility Goal
Supports builds that need to preserve OE EPB module, switch logic, and auto-hold behavior where the vehicle supports it.
Single-Piston Rear Design
Rear single-piston caliper layout with one-piece piston and dust boot for parking-brake duty.
Fabrication-Oriented Use
Built for custom conversion projects where bracketry, clocking, wiring, and rear-corner packaging must be verified.

Package List
EPB Calipers ×2
One pair of rear single-piston electronic parking brake calipers with high-temperature gloss coating.
Brake Pads
Brake pads for the supplied EPB calipers.
Calipers and pads only. Brake rotors, brake lines, caliper brackets, rotor hats, mounting hardware, electrical harnesses, and installation accessories are not included.
The Application Review Process
Because these EPB calipers are used in custom rear brake conversions, fitment cannot be assumed from vehicle model alone. Correct integration depends on the rear knuckle, rotor diameter, rotor thickness, hat offset, primary performance caliper, wheel clearance, EPB motor connector, and vehicle control logic.
1. Rear-Corner Layout Review
We review the vehicle, rear knuckle or upright, target rotor diameter, rotor thickness, hat offset, primary performance caliper, and wheel clearance envelope.
2. EPB Compatibility Check
Connector pinout, EPB motor logic, OE module behavior, auto-hold function, and parking-brake actuation requirements must be checked before installation.
3. Fabrication Approval
The installer confirms bracket design, caliper clocking, clearance around the primary brake caliper, wiring path, and service access before the calipers are integrated into the build.
If you are unsure whether your rear knuckle, EPB connector, rotor package, or primary rear caliper layout is suitable, Contact us before ordering so the application can be reviewed.
Installation Realities
This is a fabrication-oriented component, not a universal bolt-on package. Correct integration depends on the complete rear corner layout and the performance caliper it shares the rotor package with.
- Verify rotor diameter, thickness, and hat offset before ordering.
- Confirm EPB caliper clocking around the rotor with the primary performance caliper installed.
- Measure rear knuckle or upright mounting envelope before bracket design.
- Check wheel barrel and spoke clearance through the full suspension range.
- Confirm EPB motor connector pinout and electrical compatibility with the vehicle.
- Confirm that the included EPB brake pads match the final rotor package and rear-corner layout.
- Use an experienced brake fabricator or qualified installer for bracketry, wiring, clocking, and integration.
Fabricator-only product. Do not assume direct fitment on any vehicle. Specification, bracketry, EPB wiring, pad-to-rotor alignment, and integration must be handled by an experienced brake fabricator or qualified installer.
Frequently Asked Questions
Is this a complete rear brake kit?
No. This product includes only a pair of dedicated EPB rear single-piston calipers and brake pads for those EPB calipers. Brake rotors, brake lines, caliper brackets, rotor hats, mounting hardware, and wiring accessories are not included.
What is this EPB caliper used for?
It is used in custom rear brake conversions where the main hydraulic rear caliper does not include an electronic parking-brake motor, but the vehicle still needs to retain EPB function.
Are brake pads included?
Yes. Brake pads for the supplied EPB calipers are included. The product still does not include brake rotors, brake lines, caliper brackets, rotor hats, mounting hardware, wiring harnesses, or installation accessories.
Will it work on any vehicle with EPB?
Not without verification. Connector pinout, motor logic, OE EPB module behavior, rear knuckle geometry, rotor dimensions, pad-to-rotor alignment, and caliper clocking must be confirmed for each application before ordering.
What rotor size and wheel size does it need?
Recommended minimum wheel size is 18 in. Rotor diameter, rotor thickness, and hat offset must match the complete rear brake build and be confirmed during the application review.
Does it preserve auto-hold and OE EPB switch function?
When the caliper motor is compatible with the OE EPB harness and control logic, it can operate through the factory EPB module and switch, including auto-hold where the vehicle supports it. Compatibility must be verified before installation.
Can I install this myself?
This product should be installed by an experienced brake fabricator or qualified shop. Bracketry, caliper clocking, pad-to-rotor alignment, EPB wiring, electrical compatibility, and rear-corner clearance all need to be verified.

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
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.
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 diameter alone is not enough.
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
