Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather necessary tools and parts.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear; if they are less than 3mm thick, they need replacing.
Remove Old Pads: Unbolt the caliper using a socket set and lift it away from the rotor. Remove the old brake pads.
Install New Pads: Apply brake grease to the backing plate of the new pads. Slide the new pads into place.

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors: Measure rotor thickness and inspect for damage. If warped or below minimum thickness, replace.
Remove Rotors: Unbolt the caliper bracket and rotor.
Install New Rotors: Place the new rotor onto the hub, ensuring it sits flush. Reinstall the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and torque the bolts to manufacturer specifications (usually 25-35 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern.
Lower the vehicle and perform a test drive to ensure proper brake function.
