Key parameters

Type and scheme of operation of the brake system:

Foot brake Diagonalno the divided double hydraulic contour; right forward / left back (primary contour) and left forward / right back (secondary contour). The brake disks established outside, blown in front on forward and back wheels. The one-piston floating supports established on forward and back wheels. On some models the anti-blocking system of brakes (ABS) with individual contours on forward wheels and one contour on both back wheels is installed. The vacuum amplifier of brakes for the models which are not equipped with the ABS system and hydraulic strengthening of brakes for the models equipped with the ABS system. On some models the traction control system combined with the ABS system is installed.
Emergency brake Dvukhtrosikovy operated by the lever, attached to back brake disks.
