⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the 12V battery before working on electrical systems.
•Allow the brakes and electric components to cool before inspection to avoid burns.

Symptoms

•Burning rubber odor in the cabin or outside the vehicle
•Unusual noises from brakes or electric motors
•Decreased braking performance
•Warning lights on the dashboard (e.g., brake warning light)
•Excessive heat emanating from wheels or electric motor area

Diagnostic Steps

1
Check for any visible signs of melted or damaged rubber components, such as hoses, wiring, or brake pads.
2
Inspect brake pads and rotors for signs of wear or overheating. Look for discoloration or unusual wear patterns.
3
Use the vehicle's onboard diagnostics to check for any error codes related to the battery, motors, or electrical systems.
4
Perform a short test drive to replicate the smell and observe if any performance issues arise, especially related to braking.
5
Use an infrared thermometer to measure the temperature of the brake components and electric motor after driving.
