2009 Toyota Tundra Brake Master Cylinder Parts Q&A

• Q: How to remove and replace the brake master cylinder on 2009 Toyota Tundra?

  A: A proper brake master cylinder replacement process starts with disconnection of the negative battery cable followed by 90-second minimum wait time for the navigation system to save settings before shutdown of the ignition switch. The next step requires professionals to drain brake fluid while minimizing exposure of the drained liquid to painted areas. Users must disconnect the brake fluid level warning switch connector prior to breaking the union nut wrench (12 mm) to detach the front No. 1 brake tube (labeled A) and the rear No. 1 brake tube (labeled B) from the brake master cylinder. Brake booster vacuum pressure must be bled several times by depressing the pedal as the technician removes the brake master cylinder from its mounting position at the brake booster by unscrewing the two bracket nuts.
