However, if you're determined to do it yourself, here's a general overview. Remember this is a simplified overview and may not cover all variations depending on the year and model of your Buick Riviera. Always consult a repair manual specific to your vehicle's year and model.
Tools You'll Likely Need:
* Jack and jack stands: Essential for safety. Never work under a car supported only by a jack.
* Wheel chocks: To secure the other wheels.
* Lug wrench: To remove the wheels.
* Wheel wrench: To tighten the lug nuts correctly.
* Caliper piston compression tool: To push the caliper piston back in.
* C-clamp or similar tool: May be needed for some caliper designs.
* Sockets and wrenches: Various sizes, depending on your Riviera's specific components.
* Brake cleaner: To clean brake parts.
* Torque wrench: To tighten bolts to the manufacturer's specifications.
* New brake pads and rotors (possibly calipers and other components): Get the correct parts for your vehicle. Check your vehicle's VIN and use a reputable parts source.
* Gloves and safety glasses: Protect yourself from grease and debris.
* Repair manual: Crucial for specific instructions and torque specifications.
General Steps (This is NOT a complete guide):
1. Safety First: Park on a level surface, engage the parking brake, chock the wheels, and use jack stands to safely lift the vehicle.
2. Remove the Wheel: Loosen the lug nuts before jacking up the car, then remove the wheel.
3. Inspect the Brake System: Carefully examine the brake pads, rotors, calipers, and brake lines for wear, damage, or leaks.
4. Remove the Caliper: This involves removing caliper mounting bolts. You might need to support the caliper with wire or a bungee cord to keep it from hanging by the brake line.
5. Compress the Caliper Piston: Use the specialized tool to push the piston back into the caliper housing. This creates space for the new, thicker brake pads.
6. Remove the Old Brake Pads: These are typically held in place by retaining clips or pins.
7. Install the New Brake Pads: Insert the new pads, ensuring they're properly seated.
8. Inspect and Replace Rotors (If Necessary): Check rotors for wear, scoring, or excessive rust. Replace if needed.
9. Reinstall the Caliper: Mount the caliper back onto the brake bracket, ensuring the bolts are tightened correctly.
10. Bleed the Brakes (Crucial): After reinstalling the calipers, you MUST bleed the brake lines to remove air bubbles. This is a vital step to ensure proper braking performance. This often involves using a brake bleeder tool and another person to pump the brake pedal.
11. Reinstall the Wheel: Tighten the lug nuts to the correct torque specification (found in your repair manual).
12. Lower the Vehicle: Carefully lower the vehicle and remove the jack stands.
13. Test the Brakes: Test the brakes thoroughly in a safe, controlled environment *before* driving the vehicle normally. The brakes may feel different initially, and it will take some driving to get the new pads to bed in.
Again, this is a simplified overview and may not be suitable for all Buick Riviera models. Use a repair manual specific to your car for detailed instructions and safety precautions. Incorrect brake work can be extremely dangerous. If you have any doubts, consult a qualified mechanic.
