CAUTION: No indication will be given via the

Parking Brake Burnishing
This procedure is recommended for new vehicles where less
lever actuation force is required. This procedure is mandatory
whenever the driveline brake shoes or brake drum are
replaced.
WARNING! If a new drum or new brake shoes
are installed, the driveline brake must be burnished.
Failure to properly burnish the parking
brake before putting it in service could result in
an inoperative parking brake, possible vehicle
rollaway, and serious personal injury or damage
to the vehicle.
1. Drive the vehicle at 15 mph (24 km/h) in a low gear
(first or second) on a dry, hard road surface.
2. Apply the parking brake lever with a moderate force
(approximately 40 pounds) until the vehicle is
brought to a stop. Do not allow the wheels to lock up.
