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.

See Park

Brake Cable Adjustment on page 5-24.

•

Check the park brake cables, equalizer, and linkage for damage. The cables should not come in con-
tact 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.

•

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 follow-

ing WARNING.

ý

WARNING

• Use only approved replacement brake pads designed for your vehicle.

• Use only DOT 5 brake fluid.
