2002 Toyota Tundra Brake Master Cylinder Parts Q&A

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

  A: You should initiate Brake Master Cylinder servicing by taking out the reservoir with its set screw then gently pulling it out following a torque recommendation of 1.8 Nm (18 kgf-cm, 16 inch lbs.). Start by extracting both the grommets and then proceed with taking off the reservoir cap together with its strainer. Follow these steps to secure the cylinder in a vise and set a screwdriver to push the pistons through their full range of motion for removing the piston stopper bolt together with its gasket while maintaining a torque of 10 Nm (100 kgf-cm, 7 ft. lbs.). The screwdriver technique should be used to push pistons into their chamber before using snap ring pliers to retrieve the snap ring using taped screwdriver tips. During removal of the No. 1 piston and spring push them directly out to protect the cylinder bore while keeping the rubber piston lips free from damage during reinstallation. The procedure to remove the No. 2 piston and spring includes setting up the work table with a rag positioned at least 100 mm (3.94 inch) away from the block tops along with two wooden blocks. Lightly strike the cylinder flange against the blocks until the components fall free. The bore inspection must check for rust and scoring while cleaning or replacing the cylinder as needed. Simultaneously an inspection of the cylinder confirms its wear and damage requiring similar actions for cleaning or replacement. Lithium soap base glycol grease should be applied to rubber parts which the arrows indicate for the reassembly process.
