Detailed Description

The MPA Electrical NM4210 is a brake master cylinder designed for vehicles equipped with front disc brakes, including the 2004-2008 Cadillac XLR and 2005-2008 Chevrolet Corvette.

Installation Notes and Tips

Before installation, confirm the vehicle uses front disc brakes and verify the 2-hole mounting pattern, 1-inch bore, and mounting hole diameter of 0.420 inch. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit and supports proper pedal response. Use DOT 3 brake fluid only, and inspect the brake lines, booster interface, and reservoir connections during service.
