Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Tools Required: Jack, jack stands, 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 and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench, brake cleaner, wire brush.
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
3. Inspect brake pads for thickness; replace if less than 3mm.
4. Check the rotor surface; replace if it is scored or warped.
5. Clean the rotor with brake cleaner and a wire brush if it’s usable.
6. If replacing pads, ensure to apply brake grease to the back of the new pads.
7. Reinstall the caliper and torque the bolts to the manufacturer’s specification (usually around 25-30 ft-lb).

4. Reinstall Wheel

Tools Required: Lug wrench.
Sub-steps:
1. Place the wheel back onto the hub.
2. Hand-tighten the lug nuts.
3. Lower the vehicle and then use the torque wrench to tighten the lug nuts to the correct specification (typically 80-100 ft-lb).

5. Final Inspection and Test

Tools Required: None.
Sub-steps:
1. Pump the brake pedal to ensure proper pad seating.
2. Check for any unusual noises or issues during a test drive.
