Fig. 6.67. Hydraulic control unit

The brake system with ABS is double-circuit and diagonal. Strengthening in the brake system is carried out by means of the vacuum amplifier (fig. 6.67).
The hydraulic block and the control unit form one device. Therefore it is called the hydraulic control unit.
Thanks to direct connection of the called components the number of sources of mistakes decreases. Preventive repair of the hydraulic control unit is carried out by a replacement method.
The screws connecting separate knots of the hydraulic control unit are not allowed to be unscrewed.
