Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, jack stands.
Steps:
1. Remove the wheel covering the affected brake assembly.
2. Use the socket set to remove the caliper bolts and slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any sticking or damage; replace if necessary.
5. Install new brake pads, ensuring they fit snugly into the caliper bracket.

3. Inspect and Resurface/Replace Rotors

Tools Required: Rotor measuring gauge, torque wrench.
Steps:
1. Measure the thickness of the brake rotors using a rotor measuring gauge.
2. If rotors are within specifications, use a brake lathe to resurface; if not, replace with new rotors.
3. Install the rotors, ensuring they are clean and free of grease.
4. Torque the rotor mounting bolts to the manufacturer’s specifications.

4. Reassemble and Test

Tools Required: Torque wrench.
Steps:
1. Reattach the brake caliper over the new pads and rotor.
2. Torque caliper bolts to the specified settings.
3. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications.
4. Reconnect the battery and perform a brake test before driving.
