Product Details

The aluminum housing and integrated plastic reservoir support dependable fluid management, while the 1-inch bore helps maintain proper pedal feel and brake system pressure.

What It Helps Fix

- Brake fluid leakage from the master cylinder
- Uneven hydraulic pressure in the brake system
- Delayed brake response during normal driving
- Internal master cylinder wear affecting braking performance
Installation Notes
Verify vehicle fitment by year, make, model, and front disc brake configuration before installation. Bench bleeding the master cylinder before mounting helps reduce trapped air in the hydraulic system. Use DOT 3 or DOT 4 brake fluid only, and confirm the brake lines, reservoir connections, and mounting points are clean and free of damage before final assembly.
Quality Assurance
MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict protocols to support consistent braking performance after installation.
