Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Use jack stands to safely lift the vehicle.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Carefully remove the wheel to expose the brake assembly.

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are below 3mm, they should be replaced.
Replacement:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it (do not let it dangle).
3. Remove the old brake pads from the caliper bracket.
4. Install the new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping.
If replacement is needed:
1. Remove the caliper bracket bolts and take off the bracket.
2. Slide off the rotor from the hub.
3. Clean the hub surface and install the new rotor.
4. Reinstall the caliper bracket over the new rotor.

5. Reassemble and Test

Reattach the caliper over the new brake pads and tighten caliper bolts to the manufacturer’s specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specified torque (usually 80-100 ft-lbs).
Test brake function by pressing the brake pedal before driving.
