Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and place it on jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor; support it using a bungee cord to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and install new brake pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored, measure their thickness using a micrometer.
If replacement is required, remove the rotor by unscrewing the retaining screws (if applicable).
Install new rotors, ensuring they are clean and free of oil.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads.
Tighten the caliper bolts to the manufacturer's specified torque settings.
Reinstall the wheel, tightening the lug nuts in a star pattern to ensure even pressure.

6. Final Checks

Reconnect the battery and pump the brake pedal to seat the pads against the rotors.
Lower the vehicle from the jack stands.
