Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheel

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the brake pads. If they are worn down to 3mm or less, they need replacement.
Remove Old Brake Pads: Use a socket to unbolt the caliper and slide it off the rotor. Remove the old brake pads from the caliper bracket.
Install New Brake Pads: Place new brake pads in the caliper bracket, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: If the rotors are scored or warped, they will need to be replaced. Measure the rotor thickness; if it’s below the manufacturer’s specifications, replace it.
Remove Rotors: Unbolt the rotor from the hub if replacements are necessary.
Install New Rotors: Align the new rotor with the hub and bolt it in place securely.

5. Reassemble and Bleed Brakes

Reattach Caliper: Once new pads (and rotors if applicable) are in place, slide the caliper over the new pads and secure it with bolts.
Check Brake Fluid Level: Add brake fluid if necessary.
Bleed Brakes: To remove air from the brake lines, have an assistant pump the brake pedal while you open the bleeder valve on each caliper sequentially until fluid flows without air bubbles.

6. Reinstall Wheel and Test Drive

Replace the wheel and secure it with lug nuts, tightening them to the manufacturer’s torque specifications.
Lower the vehicle from the jack stands and perform a test drive to ensure the issue is resolved.
