HYDRAULIC AND PARK BRAKE SYSTEMS
Brake System Inspection
6
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 6-10.
• 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 evidence of leakage,
determine the cause and repair or replace as needed.
See Brake Pads and Caliper on page 6-6.

PARK BRAKE INSPECTION
• Apply moderate pressure to the park brake pedal. When latched, the park brake should lock the wheels and hold
the vehicle stationary on an incline of 20% or less. If not, adjust the park brake.
Adjustment – Cable Only System on page 6-18.
• Check the park brake cables, equalizer, and linkage for damage. The cables should not come in contact with
either of the rear wheels or tires.
BRAKE DISC AND PAD INSPECTION
• Inspect each brake disc. They should not be warped or have excessive scores or heat checks. Each disc should be
at least 0.150 inches (3.8 mm) at the thinnest point.
• Inspect each brake caliper assembly. They should not hold the brake pads tightly against the disc when not in use.
It is highly recommended that brake calipers, both front and rear, be thoroughly cleaned whenever the vehicle is
subjected to extreme environments that can allow a large accumulation of mud or ice/snow to become packed
between the inside of the wheel rim and the brake calipers. Pressure washing, or equivalent, is recommended to
remove such accumulation from the calipers.
WARNING
• Long-term operation of a vehicle with material packed around the calipers can inhibit brake function
and possibly damage brake components, leading to possible severe personal injury or death.
• Inspect the brake pads for wear. The pads should not be glazed or soiled with grease or brake fluid. There should
be at least 0.020 inches (0.5 mm) of brake pad material at the thinnest point.
See following WARNING.
WARNING
• Use only approved replacement brake pads designed for your vehicle.
• Use only DOT 5 brake fluid.
• Do not pump brake pedal without fluid in the reservoir or master cylinder.
