Why doesn't the spring of the handbrake button pop out?

[DiMarcus]

The handbrake button not popping out may be due to internal jamming or deteriorated lubrication of the handbrake. Lightly tap the side of the handbrake and pull it back and forth several times, or visit a repair shop to replace the lubricant. Below is relevant information: 1. Handbrake: Also known as the parking brake, its function is to provide resistance when parking, preventing the car from rolling. It is commonly referred to as the handbrake or the parking gear in automatic transmissions, which can lock the drive shaft or rear wheels. 2. Types: Handbrakes are mainly divided into electronic handbrakes and traditional handbrakes. Traditional handbrakes, also known as mechanical handbrakes, are the parking brakes commonly seen in most vehicle models. The typical handbrake is usually located at the right-hand side of the driver for easy access. Its purpose is to stabilize the vehicle after it has come to a stop, preventing accidents caused by rolling on slopes or during parking.
