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

  A: Service and repair of Brake Master Cylinder starts by disconnecting both the level warning switch connector and wire harness from their bracket. An appropriate syringe tool should be used to extract fluid from the brakes while preventing any fluid contact with painted surfaces which need immediate washing. Use Special Service Tool: 09023-00100 to disconnect the 3 brake lines from the master cylinder and 3-way and then torque them to 15 Nm (155 kgf-cm, 11 ft. lbs.). Start by removing the master cylinder through a removal sequence of its 2 nuts while also taking out the wire harness bracket, 3-way, check valve bracket and master cylinder to which you should apply 13 Nm (130 kgf-cm, 9 ft. lbs.). Only reverse the removal process for installation but first adjust the push rod length on the brake booster. The installation process requires proper filling of the brake reservoir with brake fluid followed by bleeding the system and leak and brake pedal adjustment checks.
