• Q: How to service and repair the Brake Master Cylinder on 2003 Toyota RAV4?

  A: Start Brake Master Cylinder servicing by removing the reservoir through unthreading its set screw then pulling it out while maintaining a torque of 1.8 Nm (18 kgf-cm, 16 inch lbs.) after which remove the cap and strainer. After taking out the two grommets you should mount the cylinder into a vise. The complete piston compression requires a screwdriver. Subsequently remove the piston stopper bolt together with its gasket using 10 Nm (100 kgf-cm, 7 ft. lbs.) torque. You must apply a screwdriver to push the piston into position before removing its snap ring using snap ring pliers while you must extract the No.1 piston and spring straight out by hand without harming the cylinder bore. A rag with blocks positioned on the work table at a minimum distance of 100 mm (3.94 inch) from the rag to the block tops will allow the cylinder to drop the second piston when tapped gently against the blocks. A visual examination of the cylinder bore for rust and scoring needs to be followed by wear and damage inspection. Necessary cleaning and cylinder replacement steps must be taken. The reassembly process starts with reversing the disassembly order while applying lithium soap base glycol grease to rubber parts marked by arrows.
