Solution

1. Preparation

Gather necessary tools and ensure the vehicle is parked on a level surface.
Safety gear: gloves and safety glasses.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
Remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and support it without stressing the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Sub-steps:
- Check the thickness of the brake pads.
- If worn unevenly, replace with new pads.
- Ensure the new pads are the correct type for the vehicle.

5. Inspect and Clean Brake Components

Check the caliper guide pins; clean and lubricate if necessary.
Inspect the brake rotor for uneven wear or damage; replace if necessary.
Clean the rotor surface with brake cleaner.

6. Reassemble Brake Components

Reinstall the brake pads into the caliper bracket.
Slide the caliper back over the new pads.
Torque caliper bolts to the manufacturer’s specifications.

7. Lower the Vehicle and Test

Reinstall the wheel and lower the vehicle.
Pump the brake pedal to seat the new pads before test driving.
