It can not unclamp, at this moment only car is integrally moved, is unfavorable for the maintenance of car body, adds extra-pay.
Electronics parking brake, is exactly the upgrading of traditional parking brake in fact, becomes pulling to be electronic for traditional parking brake, and electronics parking brake is exactly profit
Clamped with computer controlled motor or unclamp parking brake, parking brake is instead of with button P and draws handle.But in addition the cost of electronics parking brake compared with
It is high, it is often more important that, the function of electronics parking brake also can equally go wrong when vehicle battery failure, so as to cause to stay
Car fails, and brings potential safety hazard.
Mechanical hand brake device is only applicable on general car and minitruck at present, pedal hydraulic parking device and electricity
Control formula parking device is only used on medium-to-high grade or limousine, and generally uses machinery on high capacity waggon or car
Formula air pressure manual braking device, is commonly called as air-cut-off break.
Parking braking system now is simultaneously flawless, and either in car or various lorries, parking braking system one loses
Security incident is will result in after effect, is absolutely unsafe reliable, and some traditional holding brake devices is difficult to operate, failure it
The consequence for being difficult to retrieve is easily caused afterwards.
