7.2.13 Electromechanical parking braking system
During the age of automation and computerization, the heavy burden of applying the parking brake was shifted to the electromechanical servo.
There is only a key or a button instead of the lever inside the passenger compartment. The cables were replaced by electrical wiring, and the actuators were installed on the elements of the service brake system. With this system, the driver does not need to count the number of ratchet gear clicks while tightening the "handbrake". There is no need to worry about adjusting the parking brake cables - just press a button or pull a key and the electronics will do the job.
In addition to this simplification, a system of assistance when starting from a place under a slope, which uses a parking brake was added. As a result of this the driver got rid of one more headache - car rollback at the beginning of movement.
