I HAVE A TRUCK ISSUE ,KNOWING MOST HUNTERS,DRIVE TRUCKS?

Hey Eddie, it sounds like the sliders inside the caliper are seizing up. That will make the pads drag on the rotor and the brakes will drag.

You should be able to get a hardware kit to replace the slider bolts and internal o-rings in the calipers.

On a truck that old, there's a real good chance that the bleeder screws are going to be seized, too. They are a mother-effer to get out, if they come out at all.

A new caliper may be your best bet. I'm not sure what the price would be on an '87, but on my '05 Silverado last spring I replaced both calipers for $54 each, and the new ones have a lifetime warranty.

Good luck.

Most likely: the pads are really worn, causing the piston to extend further out. Add in a good bit of wear on the piston and when it extends further out because of the worn pads, it can c0ck a little, and jam. It would be unlikely this would happen on both sides at the same time, but maybe.

Try just replacing the pads for a quick fix. It will happen again eventually. You probably need new calipers.

chevies are famous for the front brake lines capillary-ing, they blow out inside themselves and won't let the fluid come back, and they stay stuck on, it takes a while for them to lose enough pressure to roll, but they can heat up fast. You can't tell by looking, but they are a cheap fix, before going after the calipers, pistons, etc.

Sounds like they are rusting up. You can pry the piston back in the cylinder a short distance and then pry the caliper out to the outboard side about 1/2 of that distance. They should work at least once. The correct method of fixing it is to remove the wheels and calipers, clean them up, and lube them. Re-assembly is the reverse of disassembly..

not adequate i assume on the try in basic terms 55% I used to stress the interstate daily and continually gave thank you to the super rigs via fact i see them as working women and adult adult males human beings like my self yet on a tighter schedule'

Why do you use all caps when typing? That's really annoying bro.
