Yes you have to take he hubs off.if its 2wd its not that hard ,just knock off the dust cap in center of hub,losen nut and it should slip off.oh yeah you also have to take the caliper &bracket off.if its 4wd its the same concept but just a little more aggrivating b/c of the axle shaft.

How to get rotors off ?


Rotors have to come off once or twice a year

All rust removed & you use anti-seize on all surfaces
or you get what you have

Torch?? Have to throw them away now,
& you may have ruined the Wheel Hub Bearings
with heat

A 2x4 & big hammer usually works

If you have a round driver for an air chisel,vibrate it loose

Cant get rotor off vehicle


Depending on the year and model, it may just be rusty- frozen on the hub. Sometimes you have to use a very large hammer to break it loose. But using a hammer may damage it beyond the point of being useable.

Rotors keep warping


Could be a number of problems. Here are a few.

Defective Brake Pads
  • Brake pads that are defective and/or incorrectly installed can, over time, cause brake rotors to warp and become damaged. Brake pads are responsible for squeezing against the spinning brake rotor, an action that causes a vehicle to slow down or stop. If the brake pads are bent, misshapen in any way, or aligned and/or installed abnormally, they can exert abnormal pressure on the brake rotors, a condition that can cause brake rotor warpage over time.

  • Abnormal Brake Caliper Action
  • An abnormal or malfunctioning brake caliper can result in brake rotor warpage if the degree of brake caliper dysfunction is severe enough. A brake caliper houses a set of vehicle brake pads and provides the squeezing force necessary to squeeze the brake pads against the spinning brake rotor. If a brake caliper applies too much pressure to the brake pads, or if it applies pressure inconsistently, it can cause a brake rotor to warp over time. Adequate brake caliper action is necessary for optimizing brake pad and brake rotor function.

  • Excessive Heat
  • A vehicle's braking system generates a tremendous amount of friction-related heat, heat that normally gets radiated away from the brake pads and brake rotor mechanisms. However, in cases where excessive heat is generated within a braking system and not dispersed adequately, serious brake malfunctions can occur, which can include brake rotor warpage. A stuck brake caliper, old, worn-down brake pads, or a defective brake rotor can cause excessive heat to develop in or around a brake rotor, which can cause brake rotor damage and warpage.

  • Damanged Wheel Hub Spindle
  • A brake rotor assembly is supported by and rides on a long, slender metal tube called a hub, or wheel hub assembly. The hub is what allows for the smooth, even circular motion of the spinning brake rotor. Designed with a smooth, low-friction exterior, the wheel hub assembly is critical to the proper spinning motion of the brake rotor. Any abnormalities or defects with the wheel hub assembly, including hub warpage, cracking or misalignment, can cause abnormal brake rotor rotation, which in turn can cause brake rotor warpage over time. Normally, a damaged wheel hub assembly is noticed and remedied prior to extensive brake rotor damage, as a severely damaged wheel hub assembly will cause a vehicle tire to wobble and shake.

    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.

    Cant get the rotor off of a 99 , any suggestions


    Remove the brake caliper, and caliper holder if it goes over the rotor. If it's 2 wheel drive, remove the center cap, take out the cotter pin. Remove the nut holding on the rotor. If it's 4 wheel drive, once you remove the associated brake parts, spray some WD-40 around the studs and the center of the rotor, try striking the rotor with a rubber hammer. Often the rotor will rust to the hub, on the 4 wheel drives. The 2 wheel drives, have the rotor with the hub for the bearings together, the 4 wheel drive has a "top hat" type rotor.

    How to remove rear brake rotors on a 2004 Santa Fe


    THE REAR BRAKE ROTOR IS A LOOSE ROTOR AND SHOULD COME OFF EASILY. IF NOT, IT IS POSSIBLE THAT THE ROTOR IS HELD BY RUST ONTO THE HUB OR THE BRAKE SHOES IS STILL EMBEDDED INTO THE ROTOR. REMOVE THE HANDBRAKE CABLE TO ENSURE THAT THE BRAKESHOES COLLAPSE AND TRY TO LOSEN IT AGAIN. IF SEASED ONTO THE HUB BY RUST, KNOCK THE ROTOR WITH A COPPER HAMMER TO BRAKE THE RUST WITH A RUST REMOVER.

    Vibrates when brakes are applied


    Oil around the studs and hub with wd40 and let it soak. Then smack the living hell out of it. If you break the rotor it was warped anyway and they aren't that expensive. The best place to smack is between the studs, but be careful not to hit them.

    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.
