Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Safety gear: gloves and safety glasses.

2. Remove Wheel

Loosen the lug nuts on the affected wheel using a lug wrench.
Raise the vehicle with a jack and secure with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the pads; replace if less than 3mm.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it without straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Insert new brake pads into the caliper bracket, ensuring proper orientation.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Check for grooves or warping using a straight edge.
Replace Rotors:
- Remove the caliper bracket (if applicable) to access the rotor.
- Remove the retaining screws (if present) and slide the old rotor off.
- Clean the hub surface and install the new rotor, securing it with screws.

5. Reassemble and Test

Reattach the caliper over the new brake pads and tighten caliper bolts to manufacturer specifications (usually around 20-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 100-120 lb-ft).
Test the brakes by pressing the pedal a few times before driving.
