I know, I was reading the other thread.
Parking brakes work essentially like a drum style brake. There are two shoes mounted on the inside of the brake rotor. When you pull up on the handbrake, it drives the shoes outward, causing them to grip the inside of the brake rotor. Imagine a top hat as your brake rotor, the shoes push on the part inside where your head would go.

"Be sure to jack the car up on a structural member. Otherwise, you risk damaging the chassis. I have seen jacks go through floorboards on cars before. Also be sure to support the car on jack stands. NEVER rely on a jack to keep the car up in the air.
Once jacked up, put the car in neutral, release the handbrake and pump the brakes a few times to seat the pads. Remove the rubber boot around the handbrake. You will now see two nuts in front of the lever. These nuts are used to adjust the parking brake. Loosen these nuts until the cables are completely slack.
Now go to the rear wheels. Put the car in neutral and make sure the handbrake is released. Now rotate the wheel by hand until the lug bolt hole lines up with the parking brake adjuster. This will be located about 65 degrees off centerline. If you are looking at the wheel, imagine that the very top is 0 degrees, now go right until you reach 65 degrees (about 1/8 rotation around the wheel) Once you have found the adjuster, use a screwdriver to reach in and turn the adjuster until the wheel no longer turns. Once the wheel stops turning, back the adjuster off slightly.
Now go back inside the car and set the parking brake a few times to seat the cables, and then release the parking brake. Now slowly pull the handbrake until it clicks four times. This is the position we need to have the brake at in order to adjust it. Tighten the adjusting nuts evenly on both sides until you are just able to turn the rear wheels with slight resistance.
Re-install the rubber boot over the parking brake handle and lower the car. Once on the ground, re-install the lug bolts in the rear. "
