What is the reason why the handbrake cannot be released after being pulled up?

It may be due to the failure of the handbrake ratchet mechanism. Here is an introduction to the car handbrake: Introduction: The parking brake, commonly known as the handbrake, functions to provide resistance to the car when parked, preventing it from rolling. The parking brake, also referred to as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force of the parking brake is much weaker than that of the service brake, just enough to prevent the car from rolling on a slope. System: The electronic parking brake system integrates the temporary braking during driving with the long-term braking function after parking, and it achieves parking braking through electronic control technology.
Oh, I've also experienced the issue of the handbrake being stuck in the high position. The most common cause is internal rusting of the cable, especially in humid weather or when parked in winter. The rust can jam the spring mechanism, making the handle immovable. Another possible reason is brake adhesion; if you pull it too high and tight, the rear brake pads might clamp too firmly. Additionally, wear in the handle mechanism or aging springs that fail to retract could be the culprit. The solution is to gently press the release button while slightly wiggling the lever up and down to see if a lubricating rust remover helps. If that doesn't work, park the car safely and avoid driving it, then have it towed to a repair shop for inspection and part replacement. Prevention is key—avoid pulling the handbrake to its maximum every time, and clean off dust and keep it dry, especially after summer rains.
I remember one time after I had just washed my car and parked it outdoors, I pulled the handbrake up high, and it got stuck completely, unable to move. It turned out that rainwater had caused the internal cable to rust and clump up, preventing the spring from returning to its original position. I tried gently pushing the lever while stepping on the brake pedal for assistance, and after a few attempts, it finally loosened. Since then, I've developed a habit: only pulling the handbrake halfway when parking, occasionally adding some lubricant to prevent rust, and being extra careful in winter to avoid operating it recklessly in freezing conditions. Aging cables or damage to the handle mechanism are also common factors, especially in older models which are more prone to issues. Prevention is key—regularly testing the handbrake response and addressing any signs of sticking immediately can help avoid breakdowns on the road.
