Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads; if below 3mm, replace them.
Replace Brake Pads:
- Remove the caliper mounting bolts using a socket set.
- Slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Clean the bracket and apply anti-squeal lubricant to the new pads before installation.
- Install new brake pads into the bracket and reattach the caliper.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Look for grooves or uneven surfaces on the rotors.
Replace Rotors:
- If the rotors are damaged, remove the caliper and bracket.
- Unscrew the rotor retaining screws (if equipped) and slide the rotor off the hub.
- Install new rotors by sliding them onto the hub and securing with screws.

5. Reassemble and Test

Reattach the caliper and tighten the mounting bolts to manufacturer specifications (typically around 20-30 lb-ft).
Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.
Lower the vehicle and remove the jack stands.
Pump the brake pedal to seat the pads.
