Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

1.1 Remove the wheel using a socket set.
1.2 Locate the brake caliper and remove the caliper mounting bolts with a socket wrench.
1.3 Carefully lift the caliper off the rotor and support it with a bungee cord or similar device to avoid stressing the brake line.
1.4 Remove the old brake pads from the caliper bracket.
1.5 Install new brake pads, ensuring they are correctly oriented.

3. Inspect and Resurface/Replace Rotors

3.1 Check the thickness of the rotors with a micrometer to ensure they are within specification.
3.2 If the rotors are warped, either resurface them using a brake lathe or replace them with new rotors.
3.3 Clean the rotor surface with brake cleaner before reinstalling.

4. Reassemble Components

4.1 Reinstall the caliper over the new brake pads and rotor.
4.2 Tighten the caliper mounting bolts to the manufacturer's specified torque setting.
4.3 Reinstall the wheel and tighten lug nuts in a crisscross pattern.

5. Final Checks

5.1 Reconnect the battery.
5.2 Pump the brake pedal a few times to seat the brake pads against the rotors.
5.3 Test drive the vehicle at low speeds to ensure braking is smooth and without vibration.
