Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Loosen the wheel lug nuts slightly while the vehicle is still on the ground.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Secure the vehicle with jack stands.
Remove the wheel where the noise is occurring.

3. Remove Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor; do not disconnect the brake line.
Support the caliper using a bungee cord or a suitable tool to avoid stressing the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the brake pads for wear; if they are worn down to the indicator, replace them.
If replacing, install new brake pads into the caliper bracket, ensuring they are positioned correctly.

5. Inspect and Resurface/Replace Rotors

Check the rotors for signs of wear, scoring, or warping.
If the rotors are within specifications, they can be resurfaced; otherwise, replace them.
If resurfacing, clean the rotor surface with brake cleaner.

6. Reassemble the Brake System

Reinstall the brake caliper over the new or resurfaced rotor and pads.
Torque caliper mounting bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and torque the lug nuts in a star pattern to the manufacturer’s specifications (usually around 76 ft-lbs).

7. Lower the Vehicle

Remove jack stands and carefully lower the vehicle back to the ground.
Tighten the lug nuts fully once the vehicle is on the ground.
