What causes the Roewe handbrake to not release?

[BryceMarie]

Mechanical handbrake failure to release is caused by the malfunction of the handbrake ratchet mechanism, requiring replacement of parts, or the handbrake being frozen, which can be resolved by thawing. Introduction to Parking Brake: The parking brake, commonly known as the handbrake, functions to provide resistance when the car is 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 applied by the parking brake is much weaker compared to the service brake, just enough to prevent the car from rolling on a slope. Function of Handbrake: It is used for braking when parking on flat ground or slopes, preventing the car from moving automatically when unattended, thereby avoiding traffic accidents.
