Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure vehicle is parked on a flat surface and engage the parking brake.
Disconnect the vehicle’s battery for safety.

2. Brake Inspection and Replacement

Inspect Brake Components:
- Remove the wheel using a socket set.
- Visually inspect brake pads and rotors for wear and damage.
- Check brake calipers for sticking or overheating signs.
Replace Brake Pads if Necessary:
- Remove caliper bolts using a socket set.
- Carefully lift the caliper and support it with a bungee cord (do not let it hang).
- Replace worn pads and ensure they are seated correctly.
- Reinstall the caliper and tighten bolts to manufacturer specifications (typically 25-35 Nm).

3. Electrical Component Inspection

Inspect Battery Connections:
- Check all connections for tightness and signs of corrosion.
- Clean connections with appropriate electrical cleaner if necessary.
Replace Damaged Wiring:
- If any wires appear burnt or frayed, cut and splice new wiring using appropriate connectors.
- Use heat shrink tubing to insulate connections.

4. Reassemble and Reconnect Battery

Reinstall the wheel and tighten lug nuts to manufacturer specifications (typically 100-120 Nm).
Reconnect the vehicle’s battery and ensure all connections are secure.
