What It Helps Address

• Low or inconsistent brake pedal feel
• Internal master cylinder fluid bypass
• Brake fluid leakage at the hydraulic unit
• Reduced braking response from worn seals or bore wear
• Service needs on front disc brake hydraulic systems

Installation Notes and Tips

Before installation, confirm the vehicle is equipped with front disc brakes and verify bore size, mounting hole layout, and fluid specification. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system after installation to remove trapped air. Use clean DOT 3 or DOT 4 brake fluid only, and inspect the brake booster, lines, and fittings for wear or contamination during service.

Quality Assurance

MPA Electrical tests each unit against OE specifications using proprietary processes and controlled inspection protocols to help ensure consistent braking performance out of the box.
