Solution

1. Preparation

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

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake pad spreader tool
Caliper tool (if needed)
OBD-II scanner

2. Remove Wheel

Loosen the lug nuts using the lug wrench.
Lift the vehicle using the 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

Check the thickness of the brake pads. If they are below the manufacturer's minimum specification (usually 3mm), they should be replaced.
Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket, ensuring they are properly aligned.
Use a brake pad spreader tool to compress the caliper piston back into the caliper housing if needed.

4. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotors for grooves or scoring. If they are damaged or below the minimum thickness specification, they must be replaced.
Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
Install the new rotor, ensuring it is properly seated.
Reinstall any retaining screws, torquing to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and secure it with the caliper bolts, torquing to the manufacturer’s specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and use the torque wrench to tighten the lug nuts to specifications.
Reconnect the negative battery terminal.
