Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake pad gauge or caliper.
Ensure the vehicle is parked on a flat surface, and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

Loosen the lug nuts on the wheel where you need to inspect the brake pads.
Use the jack to lift the vehicle, then secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Inspect Brake Pads

Locate the brake caliper and remove the bolts holding it in place using a socket set.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear; replace if the thickness is less than 3mm.
Check the condition of the rotor; if warped or excessively worn, consider replacing it as well.

4. Replace Brake Pads

If replacement is needed, remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads to prevent noise.
Install the new pads into the caliper bracket.
Reposition the caliper over the new pads and secure it by tightening the caliper bolts to the manufacturer’s specified torque.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the manufacturer’s specified torque.
