How to Make Parking Brake Adjustments in a Pontiac Bonneville

Adjust your Pontiac Bonneville underneath the vehicle using only a simple screwdriver. Making the adjustment at home instead of taking the car to the mechanic shop saves you time and money. Adjust the parking brake when the car starts to roll when parked on an incline. Use these instructions for years 1986 through 1999 or 2000 to 2005.

Instructions

Years 1986 Through 1999

1

Pull up and release the parking brake 10 clicks on Pontiac Bonneville years 1986 through 1990. Reduce this number to six clicks for years 1991 though 1999. Repeat the pulling up and releasing of the parking brake lever six times for all years.

2

Raise your car using the jack and support both rear wheels with the jack stands. Remove the access hole plug on the backing plates from both rear brakes.

3

Move the parking brake cable until a 1/8 inch drill bit inserts through the access hole by hand.
