Im trying to find out how to tighten my parking brake, I have a 2002 Chevrolet malibu, I just changed all the brakes on it and could not get the parking brake to be tight like it was several thousand miles ago. I can see the cable for the brake but can not see any sort of way to tighten it up at all. If you could possibly help me, i would greatly appreciate it. oh and new struts were just put on the front along with all of the brakes.

Re: parking brake tension
The hand brake on Chevy's is self adjusting, if there is a cable to tight, just follow the car from the back wheel inside to the front, in the back inside you will see a cable conduit going in to drum or disk, follow it on both sides are going to join in to one in a triangle shaped to both inside drums, right on center of joint you will see tightening mechanism like long treated bolt and two nuts, loose one and go the oposite way

Try hitting the brake off and on to see if the rpm changes when you do that with the car in park. If it does, you may have a ruptured brake booster. A fluctuating rpm while your car is in park with the brake on indicates a vacuum loss. Other things may cause a vacuum leak including the air conditioner controls inside the vehicle. Other things that cause this may be cruise control or your Air Conditioners high idle solenoid.
Hope this helps. This is out of the factory manual. Let me know if this works for you.
NOTE: Tensioner adjustment is only necessary when the tensioner, or a cable has been replaced or disconnected for service. When adjustment is necessary, perform adjustment only as described in the following procedure. This is necessary to avoid faulty park brake operation.
Fully back off cable tensioner adjusting nut at equalizer to create slack in cables.
Remove rear wheel/tire assemblies. Remove brake calipers and rotors.
Verify park brakes are in good condition and operating properly.
Verify park brake cables operate freely and are not binding, or seized.
Check park brake shoe adjustment.
Reinstall rotors and make sure rotors turn freely.
The parking brake cables may be stretched and in need of adjustment. Follow the cables along to a nut. Then you can tighten the adjusters up on both sides until you have the proper tension. Also make certain none of the brackets are bent or broken that the cables ride through.
