Jack up the front of vehicle and put in on stands. Check and see if both wheels turn freely by hand. If not, try loosening off brake line at master cylinder - bigger reservoir to relieve brake pressure. See if this helps. If relieving the pressure helps you will have to replace the master cylinder.

Replace brake hoses,they have an inner core that has ruptured and the outside rubber core is keeping pressure on the caliper with you foot off the brake. This will fix it! A common problem for this vehicle.

I agree with honeymokey, it is definitely the brakes hoses. I just finished replacing everything but the hoses to solve the same problem on my 91 GMC and it turned out I just needed a couple new hoses! Even though the hoses may look good on the outside with no leaks, the inner core gets clogged and won't release the pressure so the rotors get real hot. I wish I had known this before replacing the pads, rotors, calipers and bearings, I could have saved a bunch of money. O well, I should be set now since everything is new. Hope this helps.

2000 GMC Sierra 3500 4x4 standard cab 5.7 litre single rear wheels,Please tell me How do get the front rotors off? Any help would be much appreciated.

The brake calipers will need to come off which is the hardest part for most. Have a " C" Clamp with an 8 inch throat is needed so you can press the brake pads inward to release pressure from the rotor. Upon removing the caliper the saddle if so equipt has to be unbolted from the steering knuckle. Two bolts hold this saddle on. You may not have one depending on the design caliper this truck has. Once these parts are off the rotor will come off

One brake rotor gets very hot after 30 miles

on the wheel that is hot, jack it up and see it the wheel spins free or drags? if it drags, then loosen bleeder on the caliper, it if now spins free, you want to replace that caliper hose, if it is still dragging, then the caliper piston is stuck and you will need to replace it.

Front wheel heating up, just replaced pads rotor, caliper,outer wheel bearing, and still gets hot.

You may need to replace the flexible brake line going to the caliper. One little spec of rust or dirt will restrict the brake fluid from returning to the master cylinder which will keep the caliper depressed

Remove the wheels
Remove the brake caliper and caliper bracket

Replacing front rotor

after removing the wheel &caliper depending on rust build up you may need to hit the rotor between the wheel studs this may take some time after removal check for rust build up on hub remove rust with hammer, sanding&scraping put some anti seize lube around hub making sure no rust is caught in between depending if you are replacing the pads you have to push the caliper piston back with a large pair of chanel lock pliers or suitable tool,then you can reassemble.thanx from schleck
