WARNING
• To perform this procedure, the hydraulic system must be opened. As a result, the brakes must
be bled after the correct reinstallation of the brake components. Failure to bleed the brakes
could result in decreased braking performance due to air being trapped in the hydraulic
system. Use only DOT 5 brake fluid. See Bleeding the Hydraulic Brake System on page 6-31.
1. Chock the wheels and release the park brake and access the master cylinder.
2. Place a pan below the vehicle to collect the brake fluid.
3. Remove the two wires from the master cylinder pressure switch (4) (Figure 6-22, Page 6-30).
4. Use a 7/16-inch flare nut wrench to remove the brake line (4) from the master cylinder (Figure 6-20,
Page 6-25 or Figure 6-21, Page 6-28).
