parking brake
I adjusted my parking brake by the instructions in my haynes manual. I can feel resistance like I should, and I had the wife pull the brake lever and I watched the caliper squeeze the rotor. The problem is that it will not hold the car. Could this be glazed rotors and pads? I have plenty of material on the pads, and the rotors are not warped. The reason I ask about glazing is because my car has been subjected to it's share of brake stands over 16 years.

86ROC,
If the pads are in relatively good condition, it's more likely that the actuator screw and caliper piston are not self-adjusting properly. This is a very common problem on the older style calipers. It is also very easy to repair, but will take some time. The actuating screws and levers need to be able to operate very freely and through their entire arc. The return spring should fully return the lever to the hard stop. Typically, there is corrosion or no lubrication in the actuating screw mechanism, causing limited movement. Sometimes you may find a cable hanging up in the housing or along the body, but often it is just the actuators. Disassembling, cleaning, and reassembly of the caliper actuator with lubrication (clean brake fluid) generally solves the problem.
Since you have a Haynes manual, the directions should be there.
