Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Disconnect the battery to prevent accidental deployment of electronic systems.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake system.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
- Inspect brake pads for uneven wear and measure thickness.
Replacement:
- If pads are worn unevenly, replace both inner and outer pads on the affected axle.
- Use high-quality brake pads that meet OEM specifications.

4. Inspect Brake Calipers

Check for proper movement of the caliper pistons. If they are seized or sticking, replace the calipers.
Ensure that the caliper mounting brackets are clean and free of debris.

5. Check Rotors

Measure rotor thickness to ensure they are within manufacturer specifications.
If they are warped or below minimum thickness, replace the rotors.
Resurface rotors if they are still within acceptable limits but show signs of wear.

6. Reassemble

Reinstall the caliper over the new brake pads and secure it with the caliper bolts. Torque to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a criss-cross pattern to ensure even tightening.
Reconnect the battery.
