Feststellbremse

Feststellbremse, commonly translated as parking brake or handbrake, is a device used to secure a stationary vehicle and to provide an auxiliary braking function. It is typically engaged when the vehicle is parked to prevent movement and may also assist the service brakes at very low speeds or in a loss-of-brake situation.

There are three main variants. The mechanical type uses a hand lever or a foot pedal connected by a cable to the rear wheel brakes. When the lever is pulled or the pedal pressed, the cable tightens and applies the rear brakes; the lever is held in place by a ratchet mechanism or a return system. The cable and components wear with use and can stretch over time. The electronic or electronic parking brake (EPB) replaces the cable with electric actuators that apply the rear brakes via a switch or button. Some EPB systems can release automatically when the accelerator is pressed or after a set sequence.

Operation and usage vary by system. In manual or mechanical systems, the driver engages the brake when parked and releases it before driving. In EPB-equipped vehicles, the system is controlled by a dedicated control unit and may include automatic or manual release, as well as features like hill-hold.

Safety and maintenance. The Feststellbremse should be used whenever the vehicle is parked on an incline and should not be relied upon as the primary brake during driving. Regular inspection and maintenance of cables, levers, and actuators are important; signs of wear, corrosion, or reduced holding force warrant service. In case of a malfunction, professional inspection is recommended.
