Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel.
Lift the vehicle with a jack and secure it with 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 and lift the caliper off the rotor.
Secure the caliper with a bungee cord to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the new brake pads for proper fit and thickness.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotor surface for deep grooves or scoring; if present, replace the rotor.
Remove the caliper bracket by loosening the bolts.
Pull the rotor off the hub and replace it with a new rotor.
Ensure the new rotor is clean and free of oil or debris before installation.

5. Reassemble Braking System

Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications (typically 30-40 ft-lbs).
Reinstall the caliper over the new brake pads.
Reinstall the caliper bolts and torque to manufacturer specifications (typically 20-25 ft-lbs).

6. Reinstall Wheel and Final Checks

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 80-100 ft-lbs).
Reconnect the negative battery terminal.
