Mazda RX-7 FD
How do I perform an anti-lock braking system delete on a Mazda RX-7 FD?
Updated June 2026
Performing an ABS delete on an FD RX-7 is typically only recommended if the car is primarily dedicated to track use, as removing it takes away a significant safety net for wet driving conditions on the street 1.
Difficulty: Hard Safety Warning: Be extremely cautious if you are fabricating your own brake lines. Brake line pressure is measured in thousands of PSI, and a poorly fitted line can result in sudden and complete brake failure, which is incredibly dangerous even at city speeds 1.
How to Delete the ABS
If you are building your own setup to bypass the ABS pump, you will need:
- A brake proportioning valve
- Appropriate brake line fittings
- Custom brake lines to connect the master cylinder directly to the existing hard lines routing to the front and rear brakes 1.
If you prefer to buy a pre-made kit rather than fabricating your own high-pressure lines, there are a few options available:
- Vinnyfab: Makes an ABS delete kit, though it is primarily designed for RHD models. You may need to modify the line lengths for a LHD car, and the proportioning valve mounting may require some adjustments to fit perfectly 1.
- Alex Rodriguez Kit: A highly regarded plug-and-play kit, though production can be inconsistent, meaning you may need to source one secondhand 1.
- Sikky: Offers a pre-made ABS delete kit specifically for the FD chassis 1.
Recommended Maintenance While Access is Clear
Deleting the ABS opens up a massive amount of room in the engine bay. Since you will likely have the upper intake manifold (UIM) and engine harness off during this process, it is highly recommended to inspect or replace the following components:
- Inspect the overall condition of the fuel lines.
- Check for any evidence of fuel leaking from the Fuel Pulsation Damper (FPD).
- Replace the vacuum lines under the manifold, which is especially critical if you are still running the complex sequential twin-turbo setup.
- Inspect the condition of the rear coolant lines 1.
