How to Adjust the Parking Brake on a 2003 Suburban

by Tim Petruccio

Adjusting the parking brake on a 2003 Chevy Suburban can secure the vehicle when it is parked on an incline. Parking brakes are used to aid the parking gear of the vehicle. Adjusting the parking brake should take no longer than five minutes, even if you have never done this type of job before.

Step 1

Set the parking brake to the on position by pressing the pedal down. The parking brake pedal is on the left of the driver's side, near the kick panel.

Step 2

Start the truck and put it in reverse, with your foot on the brake.

Step 3

Ease off the brake and let the truck roll gently in reverse. If the truck does not roll by itself, gently tap the gas pedal repeatedly. Rolling the truck backward with the parking brake on will cause the automatic brake adjuster to tighten the parking brake.

Step 4

Repeat Steps 1 to 3 until you have the desired pressure in your parking brake. Release the parking brake by depressing the pedal a second time, or by pulling the parking brake release.
