02 escalade back right brake locking

[Miket1996]

I have a 02 escalade the back right brake seems to be locking up and getting hot. The brake pedal feels stiff the abs system codes i have is for the the steering position sensor havin open or short circuit. I know the caliper pins are not stuck becuase the back pads and rotors were replaced a month ago and i checked every thing.

Did this happen before the brakes were replaced? Something you can try it is to see if you can open the brake bleeder on the caliper that is getting hot and locking up while it is locked up.  If you get a squirt of brake fluid followed by an immediate release of the brakes on that wheel you will have a starting point.  Generally that result will point towards a defective flex hose, but, with ABS involved, it could point to issues in other areas. Try to get locked up again, and this time loosen the brake line fitting at the chassis end of the flex hose.  If the wheel still appears to be locked up, open the bleeder screw on the caliper again and see if the wheel releases. If it releases, it is very likely the flex hose.

It did it the slightest bit before the brake change not alot just enough to hear the pads rubbing a little. I will try to do that but i dont think the person before me had the bleeder valves open ever becuase they are on there good with alot of salt corrosion i think they might snap off.

When the brakes are working correctly they will make a light scuffing noise.

Ok well im gonna try and get the bleeder open with out it braking but if i cant how would i go about replacing the callipers and avoid doing the auto bleed can i just bleed them the old way? 

[Doug_Scott]

I have found that if you take a hammer and hit the caliper around the bleeder as well hitting 5he bleeder valve straight down to shock the bleeder.  Then try to just tighten the bleeder, not suggesting jyou actually tighten it, just aaply enough pressure to see movement.  Hit the bleeder with the hammer again, then try to open the bleeder.  Do not apply sudden pressure, slowly increase pressure.  If you can see iit start moving, stop and tighten it up again. Then try loosening it again. 

 

If you are going to replace the lines or the calipers or both, you simply leave one bleeder valve open on the caliper furthest from the master cylinder.  Do not have both bleeder valves open or both calipers removed/disconnected from brake system.. Take the master cylinder cap off and make sure you NEVER let it empty.

Ok so like a gravity bleed and dont pump the brakes at all 

[Doug_Scott]

Exactly, and be careful of level in master cylinder.

Ok so im hold off on the caliper replace memt for now becuase all of the sudden i cant gey that back brake to lock up again even thos it was doing it all the time. But now driving town  when going around a bend in the road or sometimes ramdomly the front driverside brake is now making a weird noise and braking all by it self its like the damn thing doesnt want to be driven.
