[2] [3]While automatic transmission vehicles have a "Park" gear with a parking pawl that immobilizes the transmission, it is still recommended to use the parking brake, as the pawl in the gearbox could fail due to stress or another vehicle striking ...
A Combined Braking System therefore distributes the brake force also to the non-braked wheel to lower the possibility of a lock-up, increase deceleration and reduce suspension pitch. With a single [rear] CBS the brake pressure applied on the rear brake (pedal) is simultaneously distributed to the front wheel.
