Caution
-
• When removing/installing the master cylinder, be careful not to spill brake fluid on the power brake unit vacuum sensor. Otherwise, brake fluid may get on the power brake unit vacuum sensor and damage it.
• Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.

Note
-
• Tighten the brake pipe flare nut using any commercially available flare nut wrench.
1. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)
