I just changed the rear brakes and rotors. I first used a C-Clamp to compress the piston but then realized you have to turn them (I used needle nose pliers). I was able to turn them a couple of times, put them back on, depressed the brake, then turned it a couple of times more. They turned fairly easily, so I don't think I stripped the thread (if that's how the calipers are nowadays). I did both sides. Now, as before, I just drive around the block, press the brakes a couple of times and the rotors are extremely hot (to touch). Is this normal? Or should I buy new calipers? The fronts are the same, very hot. They are not wearing excessively by any means, but the previous rotors were warped, I think. The car is a 2000 Buick LeSabre with 80,000 km on it.
Thanks in advance,
Rob

 

rotors are alway hot after use .if your galiper do not work properly you will smell burning pad just like the smell of a slipping cluth.by the way they sell a tool for screwing the rear piston on rear disk brake witch is the mecansim for the parking brake.

 

If the car coasts while driving slow and in neutral,or jack up the rear wheels and turn them,limited drag or none and your OK. The rotor and brake pads are in contact most all the time, they will be extremely hot and this is normal.
