Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electronic brake components.

2. Remove Wheel

Use a lug wrench to loosen lug nuts slightly while the wheel is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for uneven wear; note any pads that are significantly thinner than others.
Remove Brake Caliper:
- Use a socket set to remove caliper mounting bolts.
- Hang the caliper using a bungee cord or wire to avoid straining the brake line.
Remove Old Brake Pads:
- Slide the old pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of new pads (avoid the friction surface).
- Slide new pads into place in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If rotors are unevenly worn, remove them by unscrewing any retaining screws and pulling them off the hub.
Install New Brake Rotor:
- Clean the new rotor with brake cleaner to remove any protective oils.
- Align and install the new rotor onto the hub.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from the jack stands.
Tighten lug nuts to the manufacturer's torque specification (typically 76-80 ft-lbs).
Reconnect the battery if disconnected.
