Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working.

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is still on the ground.
Use the jack to lift the vehicle and place it securely on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor. Support it with a bungee cord or similar tool to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pads for thickness; replace if less than 3mm.
Apply brake grease to the back of the new brake pads to prevent noise.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. Use a caliper to measure rotor thickness.
If the rotor is damaged or below specifications, remove it by unscrewing the retaining screws or bolts.
Clean the hub surface with brake cleaner and install the new rotor.
Torque the rotor bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reattach the caliper over the new brake pads and torque the caliper bolts to specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern.
Reconnect the battery.
