Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, and a multimeter.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid activating any electronic systems.

2. Remove Wheel

Loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper: Use a socket set to remove the caliper bolts and slide the caliper off the rotor.
Check brake pads: Inspect the pads for thickness; replace if they are less than 3mm thick.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads: Slide the new pads into place, ensuring they are correctly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Remove the rotor: If the rotor is damaged, remove any retaining screws and slide it off the hub.
Inspect rotor surface: Check for warping or scoring; replace if necessary.
Clean the new rotor with brake cleaner before installation.
Install new rotor: Position the new rotor on the hub and secure it.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Reconnect the battery and check brake fluid levels, adding fluid as necessary.
