    this has happened once before and it was found to be contaminatated fluid i was told by the service manager the apprentice had put autotran in the master to top it up this caused all sorts of problems with every piece of rubber in the truck .but it only effected the front brakes.i was thinking a fluid change might be needed.

Rotors turning blue are a sign of over heating

so unless you are extra hard on your brakes or "ride" the brakes while you drive your concern is either...

sticking calipers
flex line restriction
ABS active while driving
defective master

    assuming this is the same vehicle, then take it back to the dealer

    while the lines were affective quickly by the wrong fluid you also have LOTS of rubber inside the master cylinder and ABS unit

    again... I suspect that either the master and/or ABS unit is causing excessive pressures and/or keeping the brakes applied at all times

    Therefore, given your current concerns and previous experience you should not DEMAND either a buy-back or a complete brake overhaul including, but not limited to replacing the Master, ABS unit, calipers, flexible lines and lines!!!

How to change rear brake rotors 2004 gmc savana

Removal & Installation CAUTION Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from production or aftermarket brake linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm. Exercise care when servicing brake parts. Do not sand or grind brake lining unless equipment used is designed to contain the dust residue. Do not clean brake parts with compressed air or by dry brushing. Cleaning should be done by dampening the brake components with a fine mist of water, then wiping the brake components clean with a dampened cloth. Dispose of cloth and all residue containing asbestos fibers in an impermeable container with the appropriate label. Follow practices prescribed by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) for the handling, processing, and disposing of dust or debris that may contain asbestos fibers.

The brake rotor can be removed without separating the caliper from the mounting bracket.
  1. Release the parking brake.
  2. Remove 2/3 of the brake fluid from the master cylinder.
  3. Raise and support the vehicle.
  4. Remove the tire and wheel assembly.
  5. Remove the caliper and mounting bracket as an assembly.
  6. Hang the caliper and mounting bracket assembly from the suspension using mechanics wire.
  7. Remove the rotor. Slowly turn the rotor while pulling the rotor away from the axle. (15 series).
  8. Remove the rotor. Slowly turn the rotor while pulling the rotor away from the axle. (25 series).
    NOTE If the rotor is stuck to the hub, try using a slide hammer to free it.

To install:
WARNING Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral run-out (LRO) of the brake rotor, which could lead to brake pulsation.

  1. Thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
  2. Thoroughly clean any rust or corrosion from the mating surface and mounting surface of the brake rotor.
  3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
  4. Install the rotor. Slowly turn the rotor while pushing the rotor towards the axle. (15 series).
  5. Install the rotor. Slowly turn the rotor while pushing the rotor towards the axle. (25 series).
  6. Install the caliper and the mounting bracket as an assembly.
  7. Install the tire and wheel assembly.
  8. Lower the vehicle.

My rotors are hot and have a blue tint to them. I just changed my brake pads two months ago and there almost worn out. Why are my rotors so hot.

sounds like your brake calipers are sticky. Did you clean and lube the slides on the calipers when you did the brake pad swap? If so you probably need new calipers.

Iam trying to get the rotors off ,but they seem to be rusted on so tight that it seems imposible to remove. I ve ran the e-brake adjustment out as far as I can ,whats the best way to get them off heats not...

A good 5 pound sledge hammer and ear plugs, That's what i have to use once and a blue moon and make sure first that there is no retainer clip on the wheel studs holding the rotor's in place. Good luck and hope this helps. Be safe friend.

Steering problem, can turn left w/ powersteering assisting but when I turn right I have no powersteering assistance

Does it have disc or drum brakes? If it has disc see if the rotor has turned blue from heat most likely stuck caliper. If it has drum brakes remove drum look for pieces springs adjuster e.t.c. if everything intact turn axle see if you hear noise usually a bad or locked up hub bearing will make loud humming noise.

Do i need to change the brake pads and discs???

No you don't, you can have them turn the brake disk/rotor . Turning the brake disk/rotor is when you have the surface of the disk resurfaced by having a brake lath cut the high spots down. The disk are cheap enough now that most will just replace the disk/rotor the same time they replace the brake pads. You can pick up performance drilled or slotted brake disk/rotor for almost the same price as the OEM disk/rotor. Good luck and hope this helps, you can pick up the slotted brake disk/rotor at Auto Zone for a reasonable price and they will have the step by step instruction replacing the disk and if you like to just have the disk/rotor turned, they can do they there too.

Calipers are sticking

There is a reason that Chevy only made this vehicle for a few years,,, I couldnt get them to fix anything like that. When you replace the parts,, use a full can of brake cleaner on the pins and slides so that they move freely. After that, use a proper brake lube to lube the pins before you put it all back together.
