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 negative battery terminal to prevent any electrical issues.

2. Remove Wheel

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

3. Inspect Brake Components

Visually inspect the brake pads for wear; if less than 1/8 inch of material is remaining, replace them.
Check the rotors for surface damage: if they are scored or warped, they will need resurfacing or replacement.

4. Replace Brake Pads (if necessary)

If the brake pads are worn, remove the caliper bolts and slide the caliper off.
Remove the old pads and install new pads, ensuring they are properly aligned.
Use a brake caliper tool to compress the caliper piston back into the caliper housing if replacing the pads.

5. Replace Rotors (if necessary)

If rotors are damaged, remove the rotor from the hub by removing the retaining screws (if applicable) and sliding it off.
Install the new rotor, ensuring it is seated correctly.

6. Reassemble Components

Reattach the caliper over the new pads, securing it with the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel, hand-tighten lug nuts, and lower the vehicle.

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal several times to ensure proper seating of the pads against the rotors.
