This is a general overview and may vary slightly depending on the year and model of your Buick Regal. Always consult your vehicle's repair manual for specific instructions and torque specifications.
Tools You'll Likely Need:
* Jack and jack stands (Crucial for safety)
* Lug wrench
* Wheel chocks
* Socket wrench set (metric)
* Torque wrench
* Brake caliper piston compression tool
* C-clamp (sometimes used instead of a caliper piston compression tool)
* Pliers
* Wire brush
* Brake cleaner
* New brake pads and rotors (or drums, depending on your brake system)
* Gloves
* Safety glasses
Steps (for disc brakes – most Regals have disc brakes in the front):
1. Safety First: Park on a level surface, engage the parking brake firmly, and use wheel chocks on the wheels that are not being worked on. Jack up the vehicle securely using the jack points specified in your owner's manual and place it on jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Wheel: Remove the lug nuts and take off the wheel.
3. Remove the Caliper: Locate the caliper bolts holding the brake caliper to the caliper bracket. Unscrew these bolts and carefully remove the caliper. You may need to gently pry it away from the rotor. Be careful not to damage the brake lines. Often it's helpful to hang the caliper from the suspension using a piece of wire to keep it out of the way and prevent strain on the brake line.
4. Compress the Caliper Piston: Using the compression tool, slowly compress the brake caliper piston. This is necessary to create space for the new, thicker brake pads. If you don't have a special tool, a C-clamp can sometimes work, but be extremely careful not to damage the piston.
5. Remove the Old Brake Pads: The old brake pads should now be easily removable.
6. Remove and Replace the Rotors (if needed): If the rotors are worn or damaged, they need to be removed and replaced. This usually involves removing some bolts securing the rotor to the hub.
7. Install the New Brake Pads: Install the new brake pads into the caliper bracket.
8. Reinstall the Caliper: Carefully reinstall the brake caliper onto the caliper bracket, ensuring the pads are properly seated. 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. Lower the Vehicle: Carefully lower the vehicle from the jack stands.
11. Repeat for Other Wheels: Repeat steps 1-10 for each wheel that needs new brakes.
12. Pump the Brakes: After completing all brake changes, pump the brake pedal several times to ensure the brake system is functioning correctly. You may also need to bleed the brakes, depending on whether any brake fluid was lost. If unsure about bleeding the brakes, consult a professional.
For Rear Drum Brakes (if applicable): The process for rear drum brakes is significantly different and involves removing the drum, adjusting the brake shoes, and replacing the shoes. This is generally more complex than replacing disc brake pads.
Important Considerations:
* Brake fluid is corrosive and toxic. Use appropriate safety precautions when working with it.
* Torque specifications are critical. Using the wrong torque can damage components and compromise braking performance. Always consult your vehicle's repair manual.
* If you're unsure about any step, seek professional help. Improper brake installation is dangerous.
This is a simplified overview. Always refer to a detailed repair manual specific to your Buick Regal's year and model for complete and accurate instructions. Again, if you're not comfortable with this task, take your vehicle to a qualified mechanic. Your safety is paramount.
