Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and safely supported with jack stands.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the affected wheel.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by unscrewing the caliper bolts. Check the brake pads for wear; replace if the friction material is less than 3mm.
Brake Rotors: Inspect the rotors for grooves or scoring. If they are warped or damaged, they should be resurfaced or replaced.
Calipers: Check for any signs of sticking or damage. If the caliper is faulty, replace it.

4. Replace Brake Pads and Rotors (if necessary)

If pads or rotors are worn, replace them:
- Brake Pads: Install new pads by sliding them into the caliper bracket.
- Brake Rotors: If replacing, remove the old rotor and install the new rotor, ensuring it is properly seated.

5. Reassemble Components

Reattach the brake caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 75-100 ft-lbs).
Reconnect the battery.
