Both rear brakes HOT!
I have a 2003 1500 4wd 5.3 liter V8. I just replaced my front and rear rotors and pads, and my rear brakes are getting really hot! So hot that I can't even touch the rear rims! I tried bleeding the rear calipers and it seemed to help a little. The fluid was a very very light brown. When I bled the brakes no air was in the lines. I didn't have this problem at all before. On a side note, they were the stock brakes with 116000 miles on them. It only takes about 15 miles for the brakes to get really hot. Please help!

Did you try and take calipers back off and grease them because it sounds like they are hangin up on you? Also did you take cap off of the brake fluid reservoir when doing brakes because when you suppress the calipers so the new pads will fit over the rotor, you can blow the seals in the master cylinder when pushing all that fluid back into their. Let us know how it goes

Posted By: Big bird i just went through this on a 74 GMC i own. it was a a blocked brake hose. the trash allowed the fluid to the caliper but would not return the fluid back to the master cylinder. that caused the calipers to lock shut!!!!Good point. The way to check for internally collapsed flex line is to have some push and release the brake pedal, immediately crack open the bleeder screw. If fluid spurts out and the caliper releases the flex hose is the problem.
If you can't push the caliper back with the bleeder screw open, the caliper is seized.
