Master Cylinder Replacement

NOTE: Do not spill brake fluid on the vehicle; it may damage the paint. If brake fluid gets on the paint, wash it off immediately with water.
NOTE:
  • Be careful not to damage or deform the brake lines during removal and inspection.
  • To prevent the brake fluid from flowing, plug and cover the hose ends and joints with a shop towel or equivalent.

  1. Remove the engine cover (see step 1 on REMOVAL ).
  2. Remove the intake air duct (see step 6 on ENGINE REMOVAL ).
  3. Disconnect the brake fluid level switch connectors (A), and remove the reservoir cap (B).

    • Coat the seal with silicone oil (Shin-Etsu KF 54).
    • Make sure not to get any silicone grease on the terminal part of the connectors and switches, especially if you have silicone grease on your hands or gloves.
    • Check the brake pedal height and free play after installing the master cylinder, and adjust it if necessary (see BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT ).
