A few e-brake designs push the caliper with a little screw, but GM doesn't seem to use those. They go for the more popular mini-drums.
heliman, these are activated by the e-brake pedal, not the regular brakes. I second the seized caliper diagnosis. We can help you replace a caliper or two by yourself
, but if that'* too much to handle, then drive (very
slowly) or, better, get towed to the nearest brake shop before you crash your car.
