Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. This master cylinder does not include a reservoir, cap, push rod, brake booster, sensor, or mounting hardware, so reuse or source those components as needed. Bench bleeding the master cylinder before final installation helps remove trapped air and supports proper brake pedal performance after the system is filled with DOT 4 fluid.

Quality Assurance

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols to help restore braking performance with consistent operation out of the box.
