having trouble with the brakes on a 2003 s-10 its fourwheel drive and has four wheel disk brakes, the right rear is heating up badly after driving for a bit and starts smoking badlky, i have replaced all the hardware and just replaced the caliper, i thaught maybe the piston in the caliper was sticking so i took the old one of pushed the piston back in and sprayed some lube all over the boot and in the cracks of it and it didnt do it for a bit but got worse when it did it was smoking really bad. the pads, rotors, calipers and hardware is all replaced and the only thing not new is the bracket idk what else could be causing this to happen i really need help on this one i am stumped completely..

 

it could be 3 things 1 master cyl 2 a valve that goes from your master cyl to the valve to go from one brake line to two 3 you have a pinched hose/line or a cloged.

 

Replace the brake hose.
