Brake Master Cylinder: Service and Repair
Master Cylinder Overhaul
When disassembling the master cylinder, note the position of all parts as they are removed for proper installation.
When disassembled, wash all parts in denatured alcohol or clean brake fluid only. Use an air hose to blow out all passages, orifices and valve holes.
Air dry and place parts on clean paper or lint-free cloth.
Inspect master cylinder bore for scoring, rust, pitting or etching. Any of these conditions will require replacement of the housing. Never hone the bore
of the master cylinder as this will remove the anodized surface. Inspect master cylinder pistons for scoring, pitting or distortion. Replace piston if any of
these conditions exist. If either the master cylinder housing or piston is replaced, clean the new parts with denatured alcohol or clean brake fluid, and
blow out all passages with air hose.
Examine reservoirs for foreign matter and check all passages for restrictions. If there is any indication of contamination or evidence of corrosion,
service the hydraulic system as needed, and flush the entire system, refer to Brakes and Traction Control/Brakes/Service and Repair.
When reassembling the master cylinder, use all parts contained in the repair kit. Dip all component parts in clean brake fluid, and place them on a clean
surface. To prevent faulty operation, when installing seals inspect through side outlet of the dual master cylinder housing to make certain cup lips do not
hang up on edge of hole or turn back. A piece of 3/16 inch rod with an end rounded off will be helpful in guiding cups past the hole.
