Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a stable surface and the parking brake is engaged.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with 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:
- Remove the caliper by loosening the caliper bolts.
- Carefully lift the caliper and support it without stressing the brake line.
- Check the pads for thickness; replace if less than 3mm.
Replace Brake Pads (if needed):
- Remove the old pads from the caliper bracket.
- Clean the caliper bracket and install new pads.
- Apply brake grease on the backing of the pads to prevent noise.
Reinstall the caliper and torque the caliper bolts to the manufacturer's specifications.

4. Inspect and Replace Brake Rotors

Inspect Brake Rotors:
- Check for scoring or warping. If damaged, proceed to replace.
Replace Brake Rotors (if necessary):
- Remove the caliper bracket (if not already done).
- Remove the rotor by unscrewing the retaining screws (if equipped) and pulling it off.
- Install the new rotor and ensure it is seated correctly.
- Reattach the caliper bracket and torque to specifications.
