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.

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience.
The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion.
It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient.
I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed.
This is one of those simple Amazon features that works exactly the way it should.
Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.

I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it:
Login: In the Amazon app or on Amazon.com, log in to your account.
Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI).
Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear.
Select Gift Cards: On the drop-down menu, tap Gift Cards (first option).
Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload."
Start Reload: To add funds, tap Reload.
Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload).
Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00).
Finish: Tap the orange "Buy Now" tab.
***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***

Reloading my Amazon gift card balance has been easy and convenient. I like using it when I want to keep a little money set aside for Amazon orders or make checkout quicker without thinking about which card I want to use. The process is straightforward, the balance shows up fast, and it has been reliable every time I have used it. It is also helpful for budgeting because I can add a set amount and then use that balance for regular purchases. Nothing complicated about it, which is exactly why I like it.
