2000 GMC Sierra rear passenger caliper sticking

Disconnect the cable and drive it, is it still getting excessivly hot, need to start isolating it between the hydolic and parking brake system.

not the em brake. is the caliper sticking. do i need to flush the hydro system ?

Probably not, although if it hasn't been done in thre years, then it would be a good idea. I suspect the piston is the problem AKA needs a caliper. May have been a poor rebuild job on the caliper when you bought it.

Well. The thing is it is not all the time sometimes it sticks . or it is slow to relese? when I put the new one on it did great for a day then it started again like the other one.fluid is clowdy so im going to drain the fliud and bleed all calipers till new comes out and see if that helps. If not Ill go back to advance auto parts and get another one.

Sounds like a very logical gameplan, would do the same based on what you have said.

Thanks for your help. Ill let you know how it turns out.
