Parking Brake Adjustment

So, I'm in the process of replacing rotors, brake pads, and rear parking brake assembly. I managed to reinstall most of the parking brake assembly last night. I replaced most of the pieces and parts such as the shoes, springs, adjuster, with Stainless Steel. My question is, other then following the shop manual and using the AIM, are there any tricks or tips to follow in adjusting the Parking Brake that the documentation may not cover? Any info on adjusting the Parking Brake would be helpful.

Assuming you have the rotor installed.

Turn the rotor until the adjust star can be seen through the adjusting hole. Install a flat blade screwdriver in the star wheel teeth and turn the adjusting star expanding the shoes.

To do this, move the side of the star facing you up from the floor to expand the brake shoes.

Adjust the shoes until the rotor will not move, then back it off 8 to 10 notches.

Did you install a new cable or just hardware at the wheel?

Just hardware. No cable.

Before you install the rotor take a look at the adjusting wheel assembly on each side of the car and see which way you have to turn the wheel to make it expand. They may not be the same from side to side. With the rotor off, it's easy to see how it works, but later with the rotor on, it's not easy to tell what is happening.

OK, so everything is back together and the new primary brake system functions very well. New rotors and Hawk Performance Brake Pads made a hell of a difference. The Parking Brake has been difficult to adjust. Followed the procedure several times. Followed proper bedding in of brakes but can't seem to get the parking brake to hold the car. At 40 mph when I engage the parking brake fully it slows the car gradually. If we adjust the parking brake at the shoes through the hole any further then we can't turn the rotor by hand. I don't have much more room at the equalizer on the cable to adjust. Could use some imput as to why the parking brake will not engage properly?

Sometimes driving in reverse and applying the foot brake will do it. Or if this is not working, try to raise the back of the car and secure it on jack stands. it has a slot the backing plate located in the bottom. Insert a screwdriver and turn the adjuster until the wheel becomes harder to turn. then back off one turn.

Not true on Corvette parking brakes. I will jump in here and say that I have had bad luck with the s/s shoes. I believe the shape may be off a little. I use either G.M. or Bendix. To get some adjustment range back, you may need to replace the rear cross cable. It does stretch with use. You need to adjust the cable such that the handle meets resistance about 1/2 way pulled up. Bed the shoes in by applying the parking brake several times, for about 10 seconds each time, while driving around the neighborhood. Despite what some say, they can be set up to be very effective.

Absolutely correct. The cables need to be replaced as they are stretched. No problems so far with the SS parts. Sounds like a good busy project for spring.
