Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the procedure.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper bolts and lift the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly seated.
5. Reattach the caliper and tighten the bolts to the manufacturer’s torque specifications (usually around 25-35 Nm).

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. If rotors are warped, remove them from the hub.
2. Measure the rotor thickness with a micrometer; if below minimum specifications, replace them.
3. If resurfacing, use a brake lathe to ensure a flat surface.
4. Clean the rotor surface with brake cleaner before reinstallation.
5. Reinstall the rotor and torque the retaining bolts to the manufacturer's specifications (typically 100-120 Nm).

4. Inspect Wheel Bearings and Tires

Sub-steps:
1. Lift the vehicle and remove the wheel hub.
2. Check the wheel bearings for play; replace if any looseness is detected.
3. Inspect tires for uneven wear or damage; rotate or replace if necessary.
4. Balance the tires if they are out of specification.
