What It Helps Fix

• Low or inconsistent brake pedal feel
• External brake fluid leakage at the master cylinder
• Loss of hydraulic pressure in the brake system
• Brake warning symptoms caused by master cylinder wear
• Reduced braking response on Toyota T100 front disc brake setups

Installation Notes and Tips

Before installation, confirm the vehicle is a 1994-1998 Toyota T100 with front disc brakes and verify bore size, mounting hole layout, and reservoir configuration against the original unit. Mounting hardware, push rod, brake booster, sensor, and brake pressure switch are not included. Bench bleeding the master cylinder before final installation helps remove trapped air and supports proper pedal feel after the system is filled with DOT 3 fluid.
