Tools You'll Likely Need:
* Jack and jack stands
* Wheel chocks
* Lug wrench
* Socket wrench set (metric)
* Torque wrench
* Hammer (possibly a rubber mallet)
* C-clamp or rotor removal tool (highly recommended)
* Penetrating oil (like PB Blaster)
* Wire brush (optional, for cleaning rust)
* Gloves
Procedure:
1. Safety First: Park the car on a level surface, engage the parking brake, and chock the front wheels. Raise the rear of the car using the jack and securely support it with jack stands.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper:
* Locate the caliper mounting bolts: These are usually on the back of the caliper.
* Apply penetrating oil: Spray penetrating oil onto the bolts to help loosen them.
* Remove the bolts: Use a socket wrench to carefully remove the bolts.
* Support the caliper: Use a bungee cord or wire to hang the caliper out of the way. Don't let the caliper hang by the brake line.
4. Remove the Parking Brake Cable (If Applicable): Some designs may require you to disconnect the parking brake cable from the caliper before removing the caliper. Consult a repair manual if unsure.
5. Remove the Rotor:
* Inspect the rotor: Look for any rust or corrosion that might make removal difficult. A wire brush can help clean this up.
* Use a rotor removal tool: This is the recommended method. A C-clamp or dedicated rotor removal tool will help pull the rotor off the hub. Position the tool correctly and apply firm pressure. If you don't have a tool, you *might* be able to tap the rotor off with a hammer, but be very careful not to damage the hub. Start with light taps and work your way around.
6. Clean the Hub: Clean any rust, dirt, or debris from the wheel hub where the rotor sits.
7. Installation (Reverse Order): Install the new rotor, making sure it sits flush against the hub. Reattach the caliper, ensuring the caliper bolts are tightened to the manufacturer's specifications using a torque wrench. Reinstall the wheel and lug nuts, tightening them to the correct torque specification.
8. Lower the Vehicle: Carefully lower the vehicle to the ground.
9. Test: Pump the brake pedal a few times to ensure the brakes work correctly. Test drive carefully before driving at normal speed.
Important Notes:
* Repair Manual: A 1988 Cadillac Eldorado repair manual is highly recommended. It will provide specific details for your vehicle, including torque specifications for lug nuts and caliper bolts.
* Brake Fluid: If you need to bleed the brakes after replacing the rotors, refer to your repair manual or consult a mechanic.
* Rotor Thickness: Check the minimum thickness of the rotor before installation to ensure it's within the manufacturer's specifications. If it's too thin, it needs to be replaced.
This is a general guideline. Always consult a repair manual specific to your 1988 Cadillac Eldorado for precise instructions and torque specifications. If you're uncomfortable with any part of this process, it's best to seek professional help from a qualified mechanic. Improperly done brake work can be dangerous.
