Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent any electrical issues during repair.

2. Remove Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the brake caliper by unbolting it from the bracket using a socket wrench.
Carefully slide the caliper off the rotor without straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper piston for any damage or sticking; clean or replace as necessary.
Install new brake pads into the caliper bracket, ensuring they are correctly oriented.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, remove them by unbolting the rotor from the hub.
Clean the hub surface to ensure proper installation of the new rotor.
Install new rotors, ensuring they are secured according to manufacturer specifications.

5. Reassemble and Test

Reinstall the brake caliper over the new pads and rotor, tightening the bolts to manufacturer torque specifications.
Reattach the wheel, securing it with lug nuts and lowering the vehicle.
Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper brake pad seating and restore brake pressure.
