Make parking brake adjustments to your Mercury Cougar easily and you can save yourself time and money doing the repair at home. Adjust your Mercury Cougar parking brake when your car starts to slip down the slope you park it on. Use these directions for year models 1989 and 1990.
Pull up on the parking brake until it reaches the highest position. Release the parking brake to the lowest position. Locate the parking brake between the driver's seat and the front passenger seat.
Put your Mercury Cougar in Neutral position or "N." Raise your car's rear wheels in the air using a jack and support the rear wheels with jack stands.
Get under your car and locate the threaded rod and parking brake mechanism holding the parking brake cables coming from each rear wheel.
Release the tension nut by rotating it away from the locking lever holding the threaded rod. There is a tensioner spring attached to each cable that will absorb the cable slack as you adjust the tension nut. This preloads the cables.
Rotate the locking lever forward on the threaded rod to make the cables secure.
Lower your Mercy Cougar with the jack and remove the jack stands from the rear wheels.
