Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads; if less than 3mm, replacement is needed.
Remove: Unbolt the caliper using a socket set and slide it off the rotor. Support it with a bungee cord or rope to avoid strain on the brake line.
Replace: Remove the old pads by sliding them out of the caliper bracket. Insert new pads in their place, ensuring proper alignment.

4. Inspect and Replace Brake Rotors (if necessary)

Check: Measure rotor thickness; if below specifications or if there is visible damage, replace.
Remove: Unbolt the caliper bracket to free the rotor. Slide the rotor off the hub.
Install: Clean the hub surface, place the new rotor, and reattach the caliper bracket.

5. Reassemble and Test

Reattach the caliper over the new pads and rotor, ensuring all bolts are tightened to the manufacturer’s torque specifications (typically around 80-90 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and securely tighten the lug nuts in a star pattern to the specified torque (usually 76 ft-lbs).
