- 1). Put the wheel chocks behind the rear wheels. Place a floor jack under the lower control arm and raise a front wheel off the ground. Position a jack stand under the frame and lower the Corvette onto it. Mark the position of one lug stud and the wheel, using a permanent marker, so that the wheel can be reinstalled in the proper orientation on the hub. Remove the front wheel, using the lug wrench, and place the wheel and lug nuts out of the way.
- 2). Remove the retainer clip and retainer pin that attach the caliper to the caliper bracket. Pry the caliper off the rotor and bracket, and remove the brake pads from the bracket. Remove the two caliper bracket bolts that attach the bracket to the steering knuckle. Slide the bracket off the rotor. Slide the rotor off the hub assembly.
- 3). Measure the rotor, using a micrometer, to determine if the rotor is within thickness tolerances. Replace any rotor on the front of the 1989 Corvette that is below 0.724 inch in thickness on standard duty brake systems, and 1.039 inch thickness on heavy duty brake systems. Rotors above this minimum specification can be resurfaced ( machined on a brake lathe) by your local auto repair shop or parts store. If you don't have a micrometer, the parts store or machine shop will measure the rotors for you.
- 4). Use a small wire brush to clean the contact surfaces of the caliper bracket and caliper. Apply a small amount of silicon brake lube to the caliper bracket at the top and bottom contact points on the bracket. Slide the new or resurfaced rotor onto the hub assembly, and bolt the caliper bracket in place.
- 5). Push the caliper pistons into the caliper housing using a caliper piston tool designed for multiple piston calipers like the ones on the Corvette. Snap the new pads into the caliper. Install the caliper and retaining pin onto the caliper bracket. Install the retaining clip onto the retaining pin. Reinstall the wheel and tighten the lug nuts securely. Repeat the procedure for the remaining front wheel.
- 1). Place the wheel chocks in front of the front wheels. Jack up the rear of the car and support on jack stands. Remove a rear wheel. Remove the two guide pins that attach the caliper to the caliper bracket. Slide the caliper off the bracket and rotor. Remove the two bolts that attach the caliper bracket and remove the bracket. Slide the rotor off the hub assembly. Measure the rotors for thickness. Replace any rotor that doesn't meet the minimum thickness standards. Minimum thickness is 0.724 inch for standard duty brake systems and 1.039 for heavy duty systems. If the rotors meet this minimum thickness standard, have them machined at your local auto parts store or repair shop.
- 2). Clean and lubricate, using a wire brush and brake lube, the contact points for the brake pads on the caliper bracket. Re-install the rotor and caliper bracket.Compress the caliper piston using a c-clamp.
- 3). Slip the new pads into the caliper bracket, and slide the caliper into place over the rotor and new pads. Install the slide pin bolts and tighten them securely.
- 4). Pump the brake pedal to expand the caliper piston into the pads. Top off the brake fluid and test drive to burnish the pads.
