Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Raise the vehicle and secure it on jack stands.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is still on the ground.
Lift the vehicle using the jack and place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the socket set.
- Slide the caliper off the rotor and inspect the brake pads for thickness. Replace if worn down to less than 3mm.
Brake Rotors:
- Check the surface of the rotor for scoring or grooves. If the surface is rough, either resurface or replace the rotors.
Caliper and Hardware:
- Inspect the caliper for any signs of sticking or damage. Ensure the caliper slides freely on the guide pins.

4. Replace Brake Pads and Rotors (if necessary)

If replacing brake pads:
- Remove the old pads and clean the caliper bracket with brake cleaner.
- Install new brake pads in the caliper bracket.
If replacing rotors:
- Remove the old rotor and install the new rotor, ensuring it is seated correctly.

5. Reassemble Brake System

Reattach the caliper over the new pads or rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle off the jack stands using the jack.
Tighten the lug nuts in a star pattern to the manufacturer’s specifications (typically around 80-100 lb-ft).
