Solution

1. Preparation

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

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts with a socket set, then take the wheel off.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar support.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor for warping; if warped, remove the rotor by unscrewing the retaining screws.
Clean the hub surface to ensure proper contact with the new rotor.
Install new rotors, ensuring they are torqued to the manufacturer’s specifications.

5. Reassemble and Test

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Replace the wheel and lug nuts, then lower the vehicle.
Reconnect the battery.
