Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Pads: Check the thickness of the brake pads. If they are less than 3mm, replace them.
Remove Old Pads: Remove the caliper bolts with a socket wrench and gently slide the caliper off the rotor. Support the caliper using a bungee cord or a suitable support.
Replace with New Pads: Install new brake pads in the caliper bracket. Ensure they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure rotor thickness with a micrometer; if below the minimum specified thickness (usually stamped on the rotor), replace them.
Remove Rotors: Remove the caliper bracket if necessary, and detach the rotor. Clean the hub surface to ensure proper seating of the new rotor.
Install New Rotors: Place the new rotor on the hub and secure as per manufacturer specifications.

5. Reassemble and Bleed Brakes

Reattach the caliper, ensuring all bolts are torqued to the manufacturer’s specifications.
Reinstall the wheel and tighten lug nuts in a star pattern.
Lower the vehicle and connect the battery.
Bleed the brakes to remove any air from the brake lines using a brake bleeder kit.
