Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues while working on the braking system.

2. Remove Wheel Assembly

Use a jack to lift the vehicle and support it on jack stands.
Remove the wheel lug nuts using a socket set and take off the wheel.

3. Inspect and Remove Brake Components

Inspect Brake Pads: Check for uneven wear and thickness.
Remove Brake Caliper:
- Remove caliper bolts using a socket.
- Carefully slide the caliper off the rotor. Do not let it hang by the brake line; support it with a bungee cord or similar.
Remove Brake Pads: Slide the brake pads out from the caliper bracket.

4. Replace Components

Replace Brake Pads:
- If worn unevenly, replace both left and right pads to maintain balance.
- Ensure proper orientation and alignment during installation.
Inspect/Replace Brake Rotors:
- If warped or excessively worn, replace the rotors as well.
- Ensure rotors are cleaned of any debris and properly lubricated at contact points.

5. Reassemble Components

Reattach Brake Caliper:
- Slide the caliper back over the new pads and rotor.
- Tighten caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).
Replace wheel and lug nuts, ensuring they are tightened in a star pattern.

6. Final Steps

Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to set the pads against the rotor before driving.
