• Q: How to service and repair the Brake Master Cylinder on 2003 Toyota Tundra?

  A: Service of the Brake Master Cylinder requires users to first disconnect the level warning switch connector followed by fluid removal with a syringe and prevention of brake fluid contact with painted surfaces. Operating Special Service Tool 09023-00100 allows users to disconnect the 5 or 6 brake lines from the master cylinder and detach the 3-way or 4-way components while tightening these lines to 15 Nm (155 kgf-cm, 11 ft. lbs.). When removing components, ABS-equipped vehicles require technicians to take out the 2 nuts together with wire harness bracket 3-way and check valve bracket while using a torque of 13 Nm (130 kgf-cm, 9 ft. lbs.). The absence of ABS calls for removing two nuts and the wire harness bracket 4-way along with the check valve bracket using a torque of 13 Nm (130 kgf-cm, 9 ft. lbs.). The technician must extract the master cylinder out of the brake booster area. To install the brake booster push rod should be adjusted prior to assembly while following the steps for brake booster removal in reverse order. The installation process requires brake fluid in the reservoir followed by bleeding the system before leak checks alongside brake pedal maintenance.
