Installation Notes and Tips

Before installation, verify the bore size, mounting pattern, and brake fluid type match the vehicle requirements. Bench bleeding the master cylinder before installation helps remove trapped air and supports proper pedal feel after the system is reassembled. Inspect the brake lines, booster interface, and reservoir connections for wear or contamination before filling with DOT 3 fluid.
