Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket wrench.
Take off the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Inspect: Remove the caliper by unbolting it from the bracket. Check the thickness of the brake pads; if they are below 3mm, they need replacement.
Replace: If necessary, slide the old pads out of the caliper bracket and install new pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Inspect: Check the rotors for any scoring or grooves. If they are damaged or below the minimum thickness specification, they should be replaced.
Replace: Remove the rotor by unbolting it from the hub. Install a new rotor, ensuring it is properly aligned.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads and torque the bolts to the manufacturer’s specification (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Reconnect the battery.
Press the brake pedal several times to ensure proper seating of the pads.
Perform a brake fluid check and top up if necessary.
