Diagnostic Steps

1
Inspect brake pads for wear and tear using visual inspection.
2
Check for any debris or foreign objects lodged between brake pads and rotors.
3
Measure brake pad thickness to determine if replacement is necessary.
4
Inspect brake rotors for signs of scoring or warping.
5

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Safety: Wear safety goggles and gloves.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid strain on the brake line.
- Check the brake pads for thickness; if they are worn down to 3mm or less, replacement is necessary.
Replace Brake Pads:
- If replacement is needed, remove the old pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.
- Lubricate the backing of the pads with anti-squeal grease to minimize noise.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, remove them by unscrewing any retaining screws and sliding them off the hub.
Install new rotors, ensuring they are properly aligned and secured with any retaining screws.

5. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 76-83 ft-lbs).
