Solution

1. Preparation

Gather tools and parts.
Lift vehicle using a jack and secure with jack stands.
Remove the wheel covering the affected brake assembly.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully lift the caliper off the rotor and support it with a bungee cord (do not hang by the brake line).
3. Remove old brake pads from the caliper bracket.
4. Inspect the brake pad wear indicators; replace if worn down to the metal.
5. Install new brake pads, ensuring they are properly seated in the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Sub-steps:
1. Check rotor surface for scoring; if damaged, replace or resurface it using a brake lathe.
2. Clean the rotor surface with brake cleaner to remove any debris or dust.
3. Ensure that the rotor is properly torqued to manufacturer specifications when reinstalled.

4. Reassemble and Test

Sub-steps:
1. Reattach the brake caliper and torque the caliper bolts to the manufacturer’s specifications.
2. Reinstall the wheel and lower the vehicle.
3. Pump the brake pedal several times to ensure proper engagement of the brake pads to the rotor.
4. Test the brakes at low speed to ensure noise is eliminated.
