Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheels

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheels.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Carefully slide the caliper off the rotor and support it with a wire or bungee cord (do not let it hang).
- Remove the brake pads from the caliper bracket.
Replace Brake Pads:
- If pads are worn unevenly, replace them with new pads that match the manufacturer's specifications.
- Lubricate the backing of the new pads with brake grease to prevent noise.

4. Inspect and Service Brake Calipers

Check caliper pins for smooth operation; clean and lubricate if necessary.
If calipers are sticking, rebuild or replace them as needed.

5. Check and Adjust Suspension and Alignment

Inspect suspension components (control arms, bushings, etc.) for wear.
If misalignment is present, have a professional alignment performed.

6. Reassemble and Test

Reattach the caliper, ensuring all bolts are torqued to the manufacturer's specifications.
Reinstall the wheels and lower the vehicle.
Pump the brakes to restore pedal feel before driving.
