Changed all pads on all 4 disc brakes. Have done it on various Chevy trucks in past w/ dad. Took home and we did them together this time. Brought it back home and noticed burning smell. Smell went away.A week or so later. The smell came back. Touched all the discs with the tip of my sunglasses and only the back (driver's side) disc melted the tip of my sunglasses. And the smell was coming from here. Do I need to re-bleed, do you think something is wrong with that caliper, or is it the parking brake? Or something I'm not thinking about?
Thanks,
Gabe

With the wheel off the ground does the tire spin? If its tight, crack the bleeder screw on the caliper, if it frees up you probably have a bad brake hose. If you crack it and the tire is still not moving remove the caliper and see if wheel moves. If it moves free now then you have frozen caliper slides of a frozen caliper piston. If it is still frozen then you have a frozen e brake shoes or frozen e brake cable. ***If you determine its inside e brake shoe assembly, be careful when you replace them, make note the mechanism that applies the e brake shoe, they always freeze up, make sure you free it up real good before reassembly. I hope this helps.
