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

The reason why the handbrake cannot be released after being pulled too high is due to the excessive height at which it was pulled. There are three types of braking systems: Foot Brake: The commonly used brake while driving is operated by the foot, hence it is also called the foot brake. When the driver presses the brake pedal, the braking force is transmitted mechanically or hydraulically to the wheel's braking device, generating friction. Parking Brake: Known as the handbrake, it is a braking device used to prevent the vehicle from slipping when parked. There are generally two types: one installed on the driveshaft (central braking type) and another that directly controls the rear wheel braking. Anti-lock Braking System (ABS): When driving on slippery or icy low-friction roads, excessive braking can cause the wheels to lock up and lose traction, leading to a loss of directional control. To enable effective control of the vehicle's direction on such hazardous roads, the ABS (Anti-lock Braking System) was developed.
The handbrake is stuck in the raised position and won't release—I've encountered this several times, especially in winter. Common causes include: 1. Rust or jamming in the brake cable, particularly when rust builds up in damp or dusty environments, preventing smooth release. 2. Improper adjustment—if the handbrake is usually pulled too hard or the screws are overtightened during maintenance, it can cause the system to lock in the raised position. 3. Mechanical failures, such as brake shoes failing to disengage or dust clogging the tracks. Additionally, I've experienced cases where the handbrake froze after snow when the car wasn't fully dry. For safety, avoid forcing it down or pushing the car, as this may damage components. Try gently tapping the brake drum to loosen it, or visit a repair shop promptly to inspect the cables and parts. This prevents driving with a dragging brake, which could wear out the tires.
My car has been parked outdoors for too long, and the handbrake keeps getting stuck. After some research, I found out the main reasons. It's primarily due to cable aging and rust issues, especially in areas with high salt or humidity where metal parts are prone to corrosion and sticking. Another reason is over-adjustment—pulling it too high with excessive force in one go can cause it to jam instantly. Additionally, freezing temperatures can cause mechanical parts to freeze, and operating the handbrake when it's not dry after washing the car can lead to sticking. From a safety perspective, forcing it can cause damage, so it's important not to ignore this. I've tried gently pulling and releasing the handbrake lever a few times with light movements, and sometimes it can pop free. Also, check if the rear wheels are stuck, and try moving the car slowly after starting it. However, it's best to prioritize getting a professional diagnosis to avoid bigger issues affecting daily use.
