What Causes an Automatic Transmission Brake to Lock Up and Prevent Starting?
1 Answers
Brake lock-up preventing startup is generally caused by brake system failure, excessive carbon buildup, or abnormal spark plugs. The specific reasons are as follows: Brake System Failure: When a vehicle comes to a stop and the engine shuts off, the brake system also ceases operation. Pressing the brake pedal two or three times essentially depletes all its residual energy. When brake abnormalities occur, this can lead to brake lock-up issues. Excessive Carbon Buildup: Severe carbon deposits may prevent the vehicle from starting. This condition requires professional cleaning at a repair shop. Abnormal Spark Plugs: Faulty spark plugs will cause ignition failure, making engine startup impossible.
