Solution

1. Preparation

Gather tools and materials: jack and jack stands, socket set, brake cleaner, new brake pads, torque wrench.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are smoking.
Secure the vehicle on jack stands for safety.

3. Remove Wheel Assembly

Loosen and remove the lug nuts using a socket set.
Take off the wheel to access the brake assembly.

4. Remove Old Brake Pads

Locate the caliper bolts and remove them using a socket set.
Carefully slide the caliper off the rotor. Support it with a bungee cord or hang it to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.

5. Inspect and Clean Components

Inspect the brake rotor for warping or damage; replace if necessary.
Clean the caliper and bracket using brake cleaner to remove dust and debris.
Check the caliper slides for lubrication; apply high-temperature grease if needed.

6. Install New Brake Pads

Place new brake pads into the caliper bracket, ensuring they are seated properly.
Reposition the caliper over the new pads and secure it by tightening the caliper bolts to the manufacturer’s specified torque.

7. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then tighten the lug nuts to the correct torque specification in a crisscross pattern.

8. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper pad seating and brake function.
