2011 duramax front driver side caliper sticking

[bobbyb11]

2011 duramax front driver side caliper sticking. i changed the caliper brake hose, made sure the pins were all good and greased, unplugged abs fuse, and bled the brakes many times no luck. after i bleed the brakes it will feel normal and rub a little bit but after a couple trips it will be back to sticking. when it sticks the truck pulls to the left and the steering wheel will shake, the brake pedal becomes hard and makes noise sometimes when im not even touching it just turning the wheel. when it sticks the transmission also heats up a bit and the truck will shift hard from the resistance, and i can smell the brake pads burning. what should i look into?

I would Master cylinder/hydroboost, then the ABS controller/sensor

Have you changed the caliper or just the hose? Can the caliper piston be compressed normally? where it is just 1 wheel acting up it would not be the master or booster but could be the abs. All the other wheels are normal temps? When it starts sticking crack the bleeder and see if it releases, if it does the problem is upstream, if it does not it's the caliper

Do what he said.  The piston could be sticking in the caliper, otherwise it may be an ABS problem.

I jumped to the conclusion that he had changed the caliper, you should absolutely start with what rich said in his post.
