Solved: How to remove Brake Disc Rotor on Acura Integra?

The procedure is as follows.Read it before performing this task.

Brake Disc (Rotor)

REMOVAL & INSTALLATION

See Figures 1, 2 and 3

Fig. Fig. 1: The use of a hand impact driver may be necessary to remove the brake rotor retaining screws

CAUTION

Older brake pads or shoes may contain asbestos, which has been determined to be cancer causing agent. Never clean the brake surface with compressed air! Avoid inhaling any dust from any brake surface! When cleaning brake surfaces, use a commercially available brake cleaning fluid.

Use a siphon or clean turkey baster to remove about half of the brake fluid from the master cylinder.

Raise and safely support the vehicle and remove the tire/wheel assembly.

Remove the caliper guide pin or mounting bolts.

Lift the caliper assembly away from the brake rotor.

Use a suitable piece of wire to suspend the caliper assembly from the upper control arm. This will prevent the weight of the caliper from being supported by the brake flex hose which will damage the hose.

If equipped, remove the rotor retaining screws.

Remove the brake rotor by pulling it straight off the wheel mounting studs.

To install:

If installing the rotor on the rear brakes, use a commercially available locknut wrench, or equivalent tool, to turn the caliper piston clockwise into position in the cylinder, then align the cutout in the piston with the tab on the inner pad by turning the piston back.

If installed the rotor on the front brakes, completely retract the piston into the caliper using a large C-clamp or other suitable tool.

Install the brake rotor onto the wheel hub.

Install the caliper assembly over the brake rotor and install the guide pin or mounting bolts.

Fill the master cylinder to the proper level with fresh brake fluid.

Install the tire/wheel assembly and lower the vehicle.

Pump the brake pedal until the brake pads are seated and a firm pedal is achieved before attempting to move the vehicle.

CAUTION

Do not move the vehicle until a firm pedal is obtained.

Road test the vehicle to check for proper brake operation.

InspectionSee Figure 4

Fig. Fig. 4: Use a micrometer to measure the thickness of the brake rotor. You must discard the rotor if it is not within the manufacturer's specifications

Whenever the brake calipers or pads are removed, inspect the rotors for defects. The brake rotor is an extremely important component of the brake system. Cracks, large scratches or warpage can adversely affect the braking system, at times to the point of becoming very dangerous.

Light scoring is acceptable. Heavy scoring or warping will necessitate refinishing or replacement of the disc. The brake disc must be replaced if cracks or burned marks are evident.

If the rotor needs to be replaced with a new part, the protective coating on the braking surface of the rotor must be removed with an appropriate solvent before installing the rotor to the vehicle.

Check the run-out of the hub (disc removed). It should not be more than 0.002 inch (0.050mm). If so, the hub should be replaced.

All brake discs or rotors have markings for MINIMUM allowable thickness cast on an unmachined surface or an alternate surface. Always use this specification as theminimum allowable thickness or refinishing limit. Refer to a local auto parts store or machine shop, if necessary, where rotors are resurfaced.

If the rotor needs to be replaced with a new part, the protective coating on the braking surface of the rotor must be removed with an appropriate solvent before installing the rotor to the vehicle.
