Re: Feels like my Parking Brake is on???
I went thru this with the wifes 99 Blazer.
Her's is 2wd, but she has rear disc & ABS.
The rear calipers were dragging, producing extra heat just like you described. What I found was the rubber hose to each rear disc makes 2 sharp bends and trash collects there.
Do yourself a favor, replace the rear rubber lines, and the calipers. NOTE: all the parts stores here show the L caliper, but will give you the R. You immediatly can see it when the bleeder valve is not right. Some, did not show the rubber line at all, but did show disc calipers!
Duh, you need moveable lines, not the hard line drum brakes use!!!
I also replaced the rubber line in the middle too, and blew compressed air thru the hard lines on the rear end.
I got all my stuff from NAPA.
Oh, you will hav'ta beat the rear disc's off, because of the crappy internal rear brake shoe. It's like a horse shoe, and slips off the retainer, binding on the inner part of the rotor. This will make the rotor a biotch to get off.
I tried to do this cheaply, replacing just the pads, then 1 caliper, then te other caliper, then the rubber hoses were last. The rubber hoses collapse under pressure, probably due to the sharp bends and the crap that collects in them. This makes the caliper drag.
I bled it normally, and everything is ok now, except the squeaks. Get GM pads if you can afford it, or turn the radio up.
