5.3.2 BRAKES
Brakes are self aligning and require no adjustment. They should be checked for wear every 6 months.
5.3.3 PARKING BRAKE ADJUSTMENT
As the brake pads wear thinner, the parking brake must be adjusted to
preserve proper parking brake operation. Be very cautious when performing
this adjustment or doing any work on your brakes. The parking brake
adjustment is made to hold the vehicle, load capacity and driver on 15% grade
for 15 minutes (ASME B56.8).

braking.

Place blocks ahead of and behind the wheels that will rema

Place a jack under the side of the vehicle just ahead of the r
ear wheel or behind the front wheel so it will come in
contact with the frame. Raise the vehicle until the tire clears the ground. Place jack stands under unibody for safety.

To install, tighten the lug nuts evenly in a star pattern until the nuts are all seated and torque to 65 ft. lbs. Recheck lug
nut torque with the vehicle on the ground.
NOTICE: The lug nuts must be lightly tightened in a star pattern, then torqued in a crossing pattern or the
wheel may be bent, causing it to wobble.
NOTICE: Replacement tires must be of the same size as original equipment. Increased tire load ratings are
permissible but the tire rating does not increase the vehicles rated load carrying capacity of the vehicle.
