Here's a general overview. Specific steps and tools may vary slightly depending on the exact DeVille model and trim level. Always consult a repair manual specific to your vehicle for the most accurate instructions and torque specifications.
Tools You'll Need:
* Jack and jack stands: Crucial for safety. Never work under a car supported only by a jack.
* Wheel chocks: To prevent the car from rolling.
* Lug wrench: To remove the wheels.
* Socket wrench set: Various sizes, including metric.
* Brake caliper piston compressor tool: Essential for compressing the caliper piston to make room for the new pads. A C-clamp can sometimes work in a pinch, but a dedicated tool is safer and easier.
* Wrench or socket for caliper bracket bolts: This varies depending on the vehicle. Consult your repair manual.
* Penetrating oil (PB Blaster or similar): To loosen rusty or stuck bolts.
* Clean rags or shop towels: To keep things clean.
* New brake pads: Make sure to get the correct pads for your DeVille model.
* Anti-seize lubricant: For caliper bracket bolts.
* Gloves: To protect your hands.
* Safety glasses: To protect your eyes.
General Steps (Consult your repair manual for precise details):
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks.
2. Raise and Secure: Use the jack to lift the car and securely place it on jack stands under the designated lift points (consult your owner's manual).
3. Remove the Wheel: Remove the lug nuts and take off the wheel.
4. Expose the Caliper: You should now see the brake caliper assembly.
5. Compress the Caliper Piston: Use the caliper piston compressor tool to push the piston back into the caliper. This creates space for the new, thicker brake pads. Be careful not to damage the piston seal.
6. Remove the Brake Pads: There are typically two brake pads per caliper, one inner and one outer. They're usually held in place by retaining clips or pins. You may need to gently pry them out.
7. Inspect Components: Inspect the brake rotor for wear and scoring. Inspect the caliper slides and bushings for smoothness. Replace any damaged or worn parts.
8. Install New Pads: Carefully install the new brake pads into the caliper.
9. Reinstall the Caliper: Reinstall the caliper bracket bolts, applying anti-seize lubricant to the threads to prevent future corrosion. Tighten to the correct torque specification (found in your repair manual).
10. Reinstall the Wheel: Put the wheel back on and tighten the lug nuts. Don't overtighten!
11. Lower the Car: Carefully lower the car from the jack stands.
12. Repeat for the Other Side: Repeat steps 3-11 for the other side.
13. Test the Brakes: Pump the brake pedal several times to ensure it firms up. Test drive the vehicle carefully and cautiously to ensure the brakes are working correctly.
Important Considerations:
* Brake fluid: You may need to bleed the brakes after replacing the pads, especially if you've opened the brake lines. This requires a second person.
* Rotor Condition: If the rotors are scored or worn, they'll need to be resurfaced or replaced.
* Caliper Slides: If the caliper slides are stiff or seized, they'll need to be cleaned and lubricated, or replaced.
This is a general guide only. A repair manual specific to your 2001 Cadillac DeVille is essential for accurate instructions and torque specifications. Incorrectly installed brakes can be extremely dangerous. If you have any doubts, seek professional assistance.
