Master Cylinder Inspection, Continued:
• Remove the reservoir cap and inspect the brake fluid. If the brake fluid is contaminated, purge the
brake fluid and refill the hydraulic system.
See Master Cylinder and Reservoir on page 5-20.
• Check the vent holes in the reservoir cap, and clean or replace as necessary.
• Check the diaphragm inside the reservoir cap and replace if damaged.
Brake Line Inspection
• Inspect the brake lines and fittings for leakage. They must be flexible and free of leaks, cuts, cracks or
bulges. Replace as needed.
See Hydraulic Line Replacement on page 5-17.
• Turn the steering wheel all the way from left to right and back again. Contact between the brake hoses
and any other components, especially the wheels or half-shafts, will damage the brake hoses.
• Check the back side of each brake caliper assembly for signs of brake fluid leakage. If there is evi-
dence of leakage, determine the cause and repair or replace as needed.
See Brake Pads and Caliper
on page 5-5. Also See Hydraulic Line Replacement on page 5-17.
