Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, OBD-II scanner, multimeter, brake cleaner.
Safety Warnings: Allow the engine to cool before opening the hood; ensure the vehicle is on a level surface and secured with jack stands.

2. Addressing Brake Issues

Lift Vehicle: Use a jack to lift the vehicle and secure it on jack stands.
Remove Wheels: Take off the wheels to access the brake components.
Inspect Brake Pads and Rotors:
- Check the thickness of brake pads; replace if less than 3mm.
- Inspect rotors for scoring or warping; replace if necessary.
Clean Components: Use brake cleaner to remove dust and debris from pads and rotors.
Reassemble: Reinstall the wheels and lower the vehicle.

3. Inspecting Engine Compartment

Check for Leaks: Locate and repair any fluid leaks (oil, coolant, etc.) that may cause burning.
Inspect Wiring: Look for any damaged or frayed wiring, particularly near hot components; repair or replace as needed.
Replace Damaged Components: If any components show signs of burn damage (e.g., alternator, wires), replace them accordingly.
