Installation Notes and Tips

Confirm the vehicle is a 1986-1992 Toyota Supra with front disc brakes before installation. Bench bleeding the master cylinder before mounting helps reduce trapped air in the hydraulic system. Mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included, so reuse or source those components as needed. Use only DOT 3 brake fluid and inspect the brake lines, fittings, and reservoir seals during service.
