How to adjust the Parking brake on a Trailblazer?

Answer 1

Underneath your vehicle, a steel threaded cable comes from the back of one hub and is joined by a short cable from the other hub--then the original cable runs to a threaded end with an adjuster nut in it--and one smaller nut on the end outside of that--(this is the equalizer bar)--you'll see it real close to your transmission.

You might have to jack-up the back of the vehicle???

Pull the parking brake lever up sharply and then release it. Pull the parking brake lever to the second click and leave it there. You're looking for a slight drag of the brake shoes when you spin the wheels. To increase the drag, get under at the equalizer bar and turn the adjusting nut to take up the slack in the cables. Get out and spin the rear wheels if you think it's to tight. I will say don't be afraid to crank on it for a while as in this case, a little adjustment really does not go a long way. When you think you have the drag right, go back in the car and pull the brake up the the fourth click. At this point the wheels should be locked and you should not be able to turn them even when trying hard. If you can, tighten them up a little more. Once you've done this, release the brake and make sure the wheels spin freely. If they are still binding due to the parking brake, back off the adjustment a little. And that's basically the whole adjustment procedure.

Answer 2

1st make sure that service brakes are adjusted properly
adjustment may be at the junction of the 3 cables nder the vehicle or at the handle itself (may have to remove plastic trim for access) Set to 3 clicks and wheels should be locked at that point

Answer 3

First, verify that you do not have any missing parking brake shoe linings. It is extremely common on a trailblazer for one or more of the parking brakes shoe linings to become dislodged and disintegrate. With a missing lining, normal operation of the parking brake cannot be achieved.

Next, Raise the rear wheels off the ground. Set the 4WD to 2WD mode. Shift into Neutral. Verify that the parking brake control is set to off. Remove the rear wheels, brake calipers, and brake rotors.

The parking brake shoes at each wheel will now be exposed. Separating the

shoes is a cylindrical object with a gear-like bit near it's middle. This object is called the adjuster. Rotate the adjuster gear in one direction to lengthen the adjuster, the other direction to shorten it. A longer adjuster tightens the parking brake. The parking brake should be adjusted as tight as will not drag at all when the rotor is in place. With the parking brake set to three clicks on, you should not be able to turn the wheel by hand.
