• Q: How to service and repair the Brake Master Cylinder on 2004 Toyota Avalon?

  A: Start Brake Master Cylinder servicing and repair by first removing the air cleaner cover along with the air cleaner hose. A syringe should be used for fluid extraction while braking fluid must be cleaned from painted areas because you should wash off brake fluid immediately. Remove both the level warning switch connector as well as the reservoir hose when VSC is present. Special Service Tool: 09023-00100 allows users to safely disconnect the 4 brake lines from the master cylinder and 2-way through torque application at 15 Nm (155 kgf-cm, 11 ft. lbs.). Models equipped with VSC require the use of Special Service Tool: 09023-00100 to disconnect the 5 brake lines from the master cylinder and 3-way while tightening them at 15 Nm (155 kgf-cm, 11 ft. lbs.). To remove the master cylinder tighten the nuts holding the 2 mounting points before extracting both the 2 or 3-way master cylinder while also removing the gasket with a torque setting of 13 Nm (130 kgf-cm, 9 ft. lbs.). After reverse-following the disassembly steps the technician must adjust the brake booster push rod to optimal length before mastering the installation sequence.
