Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, brake cleaner, wire brush
Sub-steps:
1. Remove the brake caliper by unbolting it from the caliper bracket.
2. Hang the caliper using a bungee cord to prevent strain on the brake line.
3. Remove the brake pads from the caliper and inspect for uneven wear.
4. Check the rotor for warping; if warped, proceed to replace it.
5. If necessary, use a brake cleaner and wire brush to clean the rotor and caliper bracket.
6. Install new brake pads and a new rotor (if needed), ensuring proper alignment.

4. Reassemble Components

Tools Required: Torque wrench
Sub-steps:
1. Reattach the brake caliper, ensuring it is secured to the caliper bracket.
2. Tighten caliper bolts to the specified torque (typically around 30-40 Nm).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually around 120 Nm).

5. Test Brake System

Sub-steps:
1. Pump the brake pedal to ensure proper pressure is restored.
2. Conduct a test drive to evaluate brake performance and check for vibrations.
