Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set and slide the caliper off the rotor.
Support the caliper using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or wear.
Install new brake pads into the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are worn or damaged, remove them by unscrewing the rotor retaining screws (if present).
Clean the hub surface to ensure proper installation of the new rotor.
Install the new rotor, ensuring it is flush against the hub.

5. Reassemble Components

Reattach the caliper over the new brake pads and rotor, ensuring it fits snugly.
Tighten the caliper bolts to the manufacturer’s specified torque settings (usually around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and remove the jack stands.
Torque the lug nuts to the manufacturer’s specifications (usually around 76 ft-lbs).
Reconnect the battery.
