1999 Trans Am Rear Rotor Problem

PATH: Brakes > Front Disc Brakes > Brake Disc (Rotor) > Removal & Installation Removal & Installation

1. Raise and support the front of the vehicle on jackstands. Remove the front wheels.
   
2. Remove the caliper assembly; do not let the caliper assembly hang by the brake hose, instead support it with a piece of wire looped around the front spring or control arm.
   
3. Remove the retaining screw from the brake rotor and remove the rotor from the hub.
   

An impact driver, No. 3 phillips screwdriver bit, and a hammer may be needed to remove the retaining screw. It is fairly easy to destroy the screw slots using an ordinary phillips screwdriver to remove the tightly driven screw (see photo).

1. To install the disc, replace the disc on the hub, screw in the retaining screw and replace the caliper assembly.

1. Raise and safely support the vehicle.
   
2. Remove the wheel and tire assembly.
   
3. Disconnect the caliper from the caliper bracket. Support the caliper out of the way with a length of wire. Do not allow the caliper to hang from the brake hose.
   
4. Remove the caliper bracket.
   
5. Remove the two 6mm screws and the brake disc. If the brake disc is difficult to remove, install two 8mm bolts into the threaded holes and tighten them evenly to prevent cocking the rotor.
   
6. Install the rotor in position. Install the two 6mm retaining screws.
   
7. Install the brake caliper. Install the tire and wheel assembly.

Realize all that is holding them on after you take off caliper slider assembly, is rust & possibly rear emergency brake shoes, inside drum inside rotor. I always engage emergency brake 1 to 2 clicks then ride around the block. That gets rid of rust & ridge on drum. Release emergency brake.Jack up truck, remove tire. Spray around center of rear hub, near studs also, with a good penetrating oil. Then remove 2 retaining bolts that hold rear caliper slider to rear spindle, & remove slider assy & caliper. Now take good sledge hammer & whack center & outside of rotor. Sometimes it takes a bunch of good hits, then they come off.

front or rear brake rotor? b sure to shut off the air ride system! the switch is located in the rear kick panel! lift and support front remove tires !the caliper has two mounting bolts remove those and hang caliper to the side using a metal coat hanger! now look at the bracket that was connected to the caliper remove those two bolts !the rotor should come off

ADJUST THE BRAKE CLEARANCE ON ALL FOUR WHEELS.

Disc only!!! Remove rear tire. Remove 2 calipar bolts. Hang calipar. Don't leave hang loose. Slide rotor off. If stuck you must adjust the emer. brake, Going around the back side of the backing plate on the bottom. Remove the rubber boot. Using a brake tool or screwdriver adjust the star wheel adjuster to remove the rotor.

jack the car take the tire off .remove the caliper ,,around middle of the rotor there is a small screw hole its is close to the tire screws you need to use a star key to take the screw off ,,that screw holds the rotor to the spindle once u take it off tap the rotor with a hammer gently to make it come lose sometimes u have to do that sometimes you don't need to ,,the rotor should come off easy ,,,replace it and put every thing back ..,,,Joe

This sounds like you have a warped rotor that either needs to be turned or the rotor needs to be replaced. This has nothing to do with the rear brake system at all.

REAR WHEEL BEARING/ HUB

Removal Procedure

1. Raise the vehicle. Refer to Vehicle Lifting in General Diagnosis.
2. Remove the wheel and the tire. Refer to Tire and Wheel Removal and Installation in Wheels, Tires and Alignment.
   1. Remove and support the brake caliper. Refer to Brake Caliper Replacement (Front) or Brake Caliper Replacement (Rear) in Brakes.
   2. Remove the brake rotor. Refer to Brake Rotor Replacement in Disc Brakes.
   3. Remove the ABS sensor wire connector.
   4. Remove the four bolts from the control arm.
   5. Remove the hub and bearing from the control arm.
   6. Remove the brake shield from the control arm.
   7. Clean the control arm face and the bore before installing the hub and the bearing.
   Installation Procedure
   
   Notice: Refer to Fastener Notice in Service Precautions.
   
   1. Install the brake shield and the hub and the bearing to the control arm with the four bolts. Be careful not to drop the hub and the bearing, as it could be damaged. Reconnect the ABS sensor. Tighten the hub and bearing bolts to 70 Nm (52 ft. lbs.).
   2. Install the brake rotor. Refer to Brake Rotor Replacement in Disc Brakes.
   3. Install the brake caliper. Refer to Brake Caliper Replacement (Front) or Brake Caliper Replacement (Rear) in Disc Brakes.
   4. Install the wheel and the tire. Refer to Tire and Wheel Removal and Installation in Wheels, Tires and Alignment. Tighten the wheel nuts to 140 Nm (100 ft. lbs.).
   5. Lower the vehicle.

Leave the center bolt in - that secures the drive axle in the hub. Use a hammer and whack the rotor hat (the raised center section where the lug studs come through) along the edge of it, where it protrudes from the surface where the pads contact it, out toward the section where the lug studs are. Hit it around the circumference every inch or so, and see if that helps.

Some cars also have a screw holding the rotor to the hub. If your hat surface is rusty, clean it up with brake cleaner and a wire brush - it may be that you have a screw or two in there that secure it to the hub, and they're just covered with rust/corrosion/dust. If you have no screws though, usually hitting it with a hammer will break it free.
