What are the causes of parking brake failure?

The causes of parking brake failure are as follows: 1. The parking brake lever cannot be fixed. 2. The parking brake fails. 3. The parking brake makes abnormal noises or is aging. 4. The gap between the friction pads and the brake drum of the automatic parking system is too large. 5. The wear on the parking brake pin shaft is severe, the gap is too large, or the parking brake rod is adjusted too long. Precautions for using the parking brake: 1. Do not tighten the parking brake while the car is moving: This can cause the braking effect to decrease due to overheating, shorten the life of the brake, or cause permanent damage to the brake. If the parking brake cannot stably hold the car or cannot fully release, immediately request an inspection from a dealer or service station. Always fully engage the parking brake before leaving the car, otherwise the car may move and cause injury or damage. 2. When parking, ensure the gear lever of a manual transmission car is in neutral: For automatic transmission cars, the gear lever should be in the P (Park) position or N (Neutral) position. Most automatic transmission cars can only remove the ignition key when in the P position.
As an ordinary person who drives frequently, I've found that parking brake failures are mostly caused by infrequent use leading to internal component adhesion or rust; long-term parking on slopes also accelerates cable slackness and breakage. Another common reason is severely worn brake pads, making the lever unresponsive, and rainy weather with high humidity can cause rust jams. Neglecting regular checks led to issues for me - once nearly causing a dangerous rollaway incident. Safety-wise, when malfunctioning during parking, vehicles can easily slide and cause collisions, especially worrying when traveling with family. I recommend developing the habit of firmly pulling and testing the handbrake, not cutting corners by neglecting it, and promptly visiting repair shops for lubrication maintenance. Simple daily upkeep like lubricating joints can be done easily - spending a little to avoid major repairs puts peace of mind and safety first.
