Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and ensure the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle using a floor jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads; replace if less than 3mm.
Replace Pads:
- Remove the caliper bolts using a socket set.
- Lift the caliper off the rotor and support it using a bungee cord (do not allow it to hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors

Inspect Rotors: Check for grooves or warping on the brake rotors.
Replace Rotors:
- Remove the caliper bracket bolts and take off the caliper bracket.
- Pull off the rotor from the hub. If stuck, tap gently with a rubber mallet.
- Install new rotors, ensuring they are seated correctly on the hub.

5. Reassemble Components

Reattach the caliper bracket and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reinstall the caliper over the new brake pads and torque caliper bolts to specifications (around 20-30 ft-lbs).
Reinstall the wheel and torque lug nuts in a crisscross pattern to specifications (around 80-100 ft-lbs).

6. Final Checks

Pump the brake pedal to ensure pads are seated properly.
Check brake fluid level and add if necessary.
