Installation Notes

Before installation, confirm the vehicle is equipped with front disc brakes and verify bore size, mounting hole spacing, and fluid type requirements. Bench bleeding the master cylinder before final installation helps remove trapped air from the hydraulic circuit and supports proper pedal feel. Inspect the brake booster, lines, and reservoir connections for wear or contamination during service.
