Tools You'll Need:
* Jack and Jack Stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel Chocks: To secure the vehicle.
* Lug Wrench: To remove the wheels.
* Socket Wrench and Sockets: Various sizes, likely including 13mm, 15mm, and possibly others depending on your specific caliper.
* C-clamp or caliper compression tool: To compress the brake caliper piston. A C-clamp works in a pinch, but a dedicated caliper compression tool is safer and easier to use.
* Pliers: May be needed to remove caliper retaining pins or clips.
* Wrench for caliper mounting bolts (if applicable): This may vary depending on the caliper design.
* Brake cleaner: To clean the caliper and rotor surfaces.
* New brake pads: Make sure you get the correct pads for your 2000 Buick Century Custom.
* Gloves: Protect your hands from grease and dirt.
* Safety Glasses: Protect your eyes from flying debris.
Steps:
1. Safety First: Park on a level surface, engage the parking brake, and use wheel chocks on the rear wheels.
2. Raise and Secure: Jack up the front of the car and securely place it on jack stands. Remember, *never* work under a car supported only by a jack.
3. Remove the Wheel: Remove the lug nuts using the lug wrench and carefully take off the wheel.
4. Expose the Caliper: You should now see the brake caliper clamping onto the rotor.
5. Compress the Caliper Piston: Use the C-clamp or caliper compression tool to slowly and evenly compress the brake caliper piston. This will create space for the new, thicker brake pads. Important: If you're using a C-clamp, protect the caliper piston from damage. Work slowly and evenly to avoid bending the piston. As you compress it, you may need to occasionally crack open the bleeder valve on the caliper to relieve pressure in the brake line and allow fluid to flow back to the master cylinder.
6. Remove the Brake Pads: There are usually two brake pads per caliper. You may find retaining pins or clips holding them in place. Remove these carefully and slide out the old brake pads.
7. Clean: Use brake cleaner to thoroughly clean the caliper, piston, and rotor surfaces.
8. Install the New Brake Pads: Insert the new brake pads into the caliper, ensuring they are properly seated. Replace any retaining pins or clips.
9. Reinstall the Caliper: Carefully reinstall the caliper onto the rotor. Make sure the caliper is properly aligned and the mounting bolts are tightened to the manufacturer's specifications.
10. Reinstall the Wheel: Replace the wheel and tighten the lug nuts. Do not overtighten.
11. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
12. Repeat for the Other Side: Repeat steps 3-11 for the other front wheel.
13. Pump the Brakes: Once both sides are done, get back in your vehicle and firmly pump the brake pedal several times to ensure the brakes are functioning properly. It may take a few pumps for the pads to seat against the rotor.
14. Test Drive: Take a short, careful test drive to check for any unusual noises or brake performance issues.
Important Considerations:
* Bleeding the Brakes: If you had to crack open the bleeder valve while compressing the caliper piston, it's a good idea to bleed the brakes afterward to remove any air that may have entered the system. This is a more advanced procedure and may require a helper.
* Rotor Inspection: Inspect the brake rotors for wear and tear. If they are severely worn or damaged, they should be replaced as well.
* Consult a Repair Manual: A repair manual specific to your 2000 Buick Century Custom is highly recommended. It will provide detailed diagrams, torque specifications, and other crucial information.
This is a general guide. The specifics might vary slightly depending on your car's exact model and configuration. Always refer to a repair manual for your vehicle for the most accurate and detailed instructions. If you are unsure about any part of this process, seek the assistance of a qualified mechanic. Improper brake repair can be dangerous.
