2002 Toyota Sequoia Parts Questions & Experts Answers

• Q: How to service and repair the Brake Master Cylinder on 2002 Toyota Sequoia?

  A: Service technicians should commence Brake Master Cylinder repairs by removing fluid with a syringe while avoiding contact of brake fluid with automobile paint until it gets washed off immediately. The technician should disconnect wires from the level warning switch and master cylinder pressure sensors before using Special Service Tool: 09751-36011 to detach brake lines. Achieve this tool connection by tightening it to 15 Nm (155 kgf-cm, 11 ft. lbs.). The master cylinder removal process starts with unfastening the two nuts and wire harness bracket and tightening them to 25 Nm (250 kgf-cm, 18 ft. lbs.) before extracting the master cylinder from the brake booster. The installation process requires performing removal steps in opposite order and afterward filling the brake reservoir with brake fluid before bleeding the brake system while inspecting for fluid leaks. When performing an upgrade of the master cylinder assembly or master cylinder pressure sensor it is necessary to conduct zero point calibrations on steering angle, master cylinder pressure, yaw rate and deceleration sensors.
