Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection method.
2
Check brake rotors for grooves, scoring, or warping.
3
Examine brake calipers for proper operation and signs of damage.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, basic hand tools (socket set), brake cleaner, torque wrench.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the front or rear wheels (depending on where the noise is coming from).
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are less than 3mm, they need replacement.
Remove the Caliper:
- Remove the caliper mounting bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar device to avoid stress on the brake line.
Replace Brake Pads:
- If worn, remove the old brake pads from the caliper bracket.
- Apply brake grease to the back of the new pads (not the friction surface) and install them in the caliper bracket.
Reattach the caliper over the new pads and tighten the mounting bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotor Condition: If the rotors are scored or warped, they should be replaced.
Remove Rotor:
- If necessary, remove the caliper bracket to access the rotor.
- Remove any retaining screws and pull the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub and secure with retaining screws if applicable.

5. Final Assembly

Reinstall the brake caliper and pads (if rotor was replaced).
Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).
Pump the brake pedal a few times to seat the brake pads against the rotors.
