What It Helps Address

• Low or inconsistent brake pedal feel
• Internal hydraulic leakage in the master cylinder
• Reduced braking response from worn hydraulic components
• Brake fluid pressure loss at the master cylinder
• Restoration of proper brake system operation after master cylinder wear

Installation Notes

Mounting hardware, reservoir, cap, push rod, gasket or seal, brake booster, sensor, and brake pressure switch are not included. Verify bore size, mounting hole spacing, and front disc brake application before installation. Bench bleeding and a complete brake system bleed are recommended after installation, and the system should be filled with DOT 3 brake fluid.

Quality Assurance

MPA Electrical remanufactures this master cylinder using an OE sample library and tests each unit against OE specifications under strict process controls. That helps ensure consistent hydraulic performance right out of the box for the listed Cadillac, Chevrolet, and GMC applications.
