Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; suspend it using a bungee cord to avoid straining the brake line.
Inspect the brake pads for thickness; replace if they are below 3mm.
- Tools Required: Socket set, bungee cord
- Parts Required: New brake pads
Apply brake grease to the backing of the new pads before installation.
Reinstall the caliper and torque bolts to the manufacturer's specification (typically around 25-35 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or abnormalities. If damaged, replace the rotors.
Remove the rotor by unscrewing the retaining screws if equipped.
Install new rotors by aligning them with the hub and securing them using the screws.
- Parts Required: New brake rotors
- Tools Required: Torque wrench

5. Reassemble and Test

Reinstall the wheel and lug nuts, torquing them to the manufacturer’s specifications (typically 76-86 lb-ft).
Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to ensure proper seating of the pads.
Test drive the vehicle to ensure noise is eliminated and brakes are functioning properly.
