Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or debris.
Install new brake pads in the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, remove them by unbolting the rotor from the hub.
Clean the hub surface before installing new rotors.
Install new rotors, ensuring they are seated correctly.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the specified torque (usually around 25-30 ft-lbs, consult specific vehicle manual for exact value).
Reinstall the wheel and tighten the lug nuts to the manufacturer’s specified torque (usually 75-85 ft-lbs).

6. Lower Vehicle

Remove jack stands and lower the vehicle to the ground.
Reconnect the negative battery terminal.
