Tools You'll Need:
* Jack and jack stands (Crucial for safety! Never work under a car supported only by a jack.)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric) with extensions and ratchet
* Brake caliper piston compressor tool (essential for compressing the caliper piston)
* C-clamp or large pliers (may be needed depending on caliper design)
* Wire brush
* Brake cleaner
* Anti-seize lubricant
* New brake pads and rotors (ensure they're the correct size and type for your Caprice)
* Torque wrench (to tighten lug nuts and caliper bolts to the correct specification – consult your repair manual)
* Safety glasses and gloves
Procedure (General Outline – Consult your repair manual for specific details):
1. Safety First: Park on a level surface, engage the parking brake, and chock the wheels. Jack up the car and securely support it on jack stands.
2. Remove the Wheel: Remove the lug nuts and carefully take off the wheel.
3. Remove the Caliper:
* Locate the caliper bolts (usually two).
* Unscrew the bolts and carefully remove the caliper. You may need to support the caliper with a bungee cord or wire to prevent it from hanging by the brake line.
4. Compress the Caliper Piston: This is crucial. Use the caliper piston compressor tool to push the piston back into the caliper bore. This creates space for the new, thicker brake pads. Some calipers may require a C-clamp or large pliers, but a specialized tool is preferred to avoid damaging the piston.
5. Remove the Old Brake Pads: The old pads should slide out easily. Clean the caliper mounting bracket and the caliper itself with a wire brush and brake cleaner.
6. Install the New Brake Pads: Insert the new brake pads into the caliper bracket.
7. Install the New Rotor (If Replacing): If you're replacing the rotors, carefully remove the old rotors. They may be held on with a few bolts or simply slide off after removing the caliper. Clean the rotor mounting hub thoroughly. Install the new rotors, ensuring they are properly seated.
8. Reinstall the Caliper: Carefully reinstall the caliper over the new pads and securely tighten the caliper bolts to the manufacturer's specified torque.
9. Reinstall the Wheel: Replace the wheel and tighten the lug nuts to the manufacturer's specified torque. Do not overtighten.
10. Repeat for Other Wheels: Repeat steps 2-9 for the other three wheels.
11. Bleed the Brakes (Crucial): After replacing the pads and rotors, you *must* bleed the brakes to remove any air that may have entered the system. This requires two people and a brake bleeder kit. Consult your repair manual for the proper bleeding procedure. Improper bleeding can result in spongy brakes or brake failure.
12. Test Drive: After bleeding the brakes, carefully test drive the vehicle. Listen for any unusual noises and check for proper brake function.
Important Considerations:
* Repair Manual: A service manual specific to your 1984 Chevrolet Caprice is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions.
* Brake Fluid: Check and top off your brake fluid reservoir before starting and after bleeding the brakes.
* Safety: Brakes are a critical safety system. If you are not comfortable performing this repair, take your vehicle to a qualified mechanic. Working on brakes incorrectly can lead to serious injury or death.
This is a simplified overview. Consult a repair manual for your specific vehicle model before attempting this repair. The procedures and components may vary slightly depending on options and specific year of manufacture. Remember, safety is paramount. If you have any doubts, seek professional help.
