What Causes the Brake to Not Release?

[MacLondyn]

Generally, it's due to a faulty brake switch. Replace the brake switch and adjust the brake cable. Below are specific details about the parking brake: 1. Introduction: The professional term for the parking brake is auxiliary brake. Unlike the main brake, it uses a steel cable connected to the rear brake to stop the vehicle. 2. Usage: Long-term use of the parking brake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, prolonged use will reduce its effectiveness, and the parking brake's travel distance will also increase. Here are some additional details: 1. Maintenance: Regularly perform appropriate maintenance and inspections on the vehicle's parking brake. Some people, due to irregular maintenance, often need to lift the parking brake twice to stop the vehicle. If not careful when parking, the vehicle may slightly move backward, so the use and maintenance of the parking brake should not be overlooked. 2. Effective Point of the Parking Brake: You can park the car in a quiet place, slowly pull up the parking brake while counting the clicks from the ratchet until the handle reaches its limit. Then calculate 70% of the total number of clicks—this position is the effective working point of the parking brake handle.
