Are the rear brakes drum? If so they need to be adjusted. There is a little slot on the backside of the brake assembly that usually has a plastic or rubber cover. Jack the rear end up and remove that cover to expose a little slot. Use a small flathead screwdriver to adjust the ratchet mechanism. To find out which way to turn it spin the wheel occasionally to see what direction will tighten the shoes. Adjust the shoes untill the wheel stops spinning then back off a turn.

Why are the Rotors getting so hot on the front and rear so hot I can not touch them.


The rotors are doing their job by getting hot
the purpose of the brakes is to change the kinetic energy of the spinning wheels to heat energy by the friction between the pads and the rotors (discs) This conversion of energy from kinetic to heat is what slows down the vehicle and stops it . The pads have no way of staying off the discs except by the air flow that is dragged under the pad by the friction with the disc So to sum up discs get hot by converting energy and the more energy you have the hotter they get
(watch high speed race cars at night and you will see the discs are white hot or bright red )
Back discs are slightly different as they don't come on as hard as the front discs and they also are affected by hand brakes out of adjustment
IF you feel that the discs are getting too hot for the distance covered there may be a problem in that the callipers are binding on the mounting bolts (pins) and are not centralizing and hence one pad will be in contact all the time This pad will show more wear then the other pad on the same disc.

I have a 2000 Chevy Cavalier... I replaced rotors pads and calliper accros the front end... Whe I start to drive the brakes seem to be perfect but the more I have to use the brakes the tighter the peddle...


To me it seems like the brakes are heating up, after you drive for half an hour touch the wheel rims and see if they are hot and if they are hot then either you have the wrong rotors or wrong pads in.

Just changed rear pads and rotors on my 2000 chev blazer..after test driving rear brakes were hot and smoking...brake pads seem to be sticking..are the calipers shot or do I need hoses or both?


  • Well when you looked at the brake pads after your drive were the pads stuck to the rotor?
  • First thing to do is double check your pad and rotor installation.
  • Also check to make sure the right parts were installed.
  • When you pushed back the pistons on your calipers did they flow back nice and smooth? Did they wedge in and get stuck? This would make the pads drag.
  • If you used grease did you get some on the pad by accident? If this is the case it will burn off.

  • How is the car stopping for you? Properly? Do you hear any grinding while driving slow? While driving fast? Over heating rotors will turn a bluish stain. That is when it is really time to be worried.
  • If your brakes are not dragging then give some time for the pads to ware in.
  • If the piston is stuck forcing the pads against the rotor all the time then you need to replace the calipers.
  • Don't forget to bleed the lines afterword.

Just changed the pads on my 2003 Chevy Silverado. Now back wheel is getting very hot. why?


Make sure you check that its not rubbing. The silverado's have a sort of strange brake setup where the brakes just ride on the rotor. If the channel isn't clean that the pads ride on then they will push on the rotor hard. Unfortunately that is the only reason your wheel could get hot. Even if the bearings in your rear were going bad your axle would get hot but not your wheel. Thanks.

Front brakes drag (more on left than right) while driving in rush hour stop-and-go traffic. Both rims get hot the left more than the right. Also have some steering wheel vibration and brake pedal pulsing....


Sounds like the pads are completely worn or either crystallized. The crystallized happens when the brakes get hot and cool water hits them, this will also warp the rotors. With the brakes pulsating, it may be the rotors are warped and have worn the brake pads uneven. I would have the rotors checked when buying new pads and if they are warped, buy new ones. If their not warped to bad, sometimes these can be machined until even but you never know how much metal will be left on the rotor.

Does the 2003 gmc yukon have rear rotors? and do the brakes need to be changed if the rotors need to be machined?


Yes, it has rear Disc Brakes, I would suggest to change the rear pads since they have to remove the rear Brake Calipers to remove the rotors and it wouldn't take much more time or labor to replace the pads at that point. That way when your rear rotors are re-installed and your new brake pads are installed your rear brakes should give you longer service life and better stopping power.

Rear brake noise after brake replacement


probably a dumb question, but if there is a backing plate, did you make sure it isnt bent and hitting the rotor? you never want to sand new rotors, although i dont think it would cause this concern. i would suggest lightly scuffing up the brake pads. this will eliminate any noise caused by the contact of the rotors and pads. if it goes away then you know its a problem with the pads/rotors.

scoring of only the inside rotors would make me think that possibly the caliper slides are frozen up. make sure they move quite freely on the slides. it is not uncommon for brake pads to score rotors though.

but brake noises at low speeds that dont' change when applying light brake pressure are usually some sort of metal or something contacting the rotor.

I have a 2002 Nissan Quest and the rear brakes are making grinding and squeaking noises while braking. The rear brakes were replaced a month ago and since then it's been making those noises. I have read...


Make sure the rotors (the disks that the tire rim are mounted on), are smooth. If they are rough, then they are wearing your break pads down. Even if the break pads are new, bad rotors will grind them down. Change the rotors...

Raise the vehicle up and remove the rims & tires

Remove the brake pads, and then remove the calipers from the caliper retention brackets, do NOT remove the brake hoses from the calipers.

Remove the caliper retaining brackets from the hub assemblies (2 large bolts on backside of the bracket)

Tap the brake rotors off of the hubs, hit them from the back side of the rotor.

No big mysteries here, this is a very easy job.
