Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the truck depending on the affected brakes.
Secure with jack stands for safety.

3. Remove Wheel

Using a socket set, loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Check the brake pad thickness; if below 3mm, replacement is necessary.
Remove caliper bolts using a socket.
Carefully slide the caliper off the brake rotor, supporting it to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated properly.

5. Inspect and Resurface/Replace Rotors

Check rotors for any signs of scoring or warping.
If necessary, have rotors resurfaced or replace them if the thickness is below minimum specifications.
Clean the rotor surface with brake cleaner before installation.

6. Reassemble the Brake Components

Reattach the caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and torque the lug nuts in a crisscross pattern to the specified torque (usually around 100 ft-lbs).

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.

8. Test Braking System

Pump the brakes a few times to ensure the pads seat correctly.
Test drive the vehicle to verify the noise has been eliminated.
