The regulator of pressure is installed on the car for the purpose of restriction of the maximum pressure of the brake fluid regarding a hydraulic actuator connected to brake mechanisms of back wheels in dependence, from dynamic load of a back axis.

Restriction of the maximum pressure allows to prevent an advancing of blocking ("skid") of back wheels concerning lobbies when braking and by that to reduce probability of a drift of the car.

In use the car springs of a back suspension bracket have residual deformations changing factory adjustment of the regulator of pressure. Therefore after the run of the new car of 1,5-2 thousand km, and further through each 30 thousand km of a run, it is necessary to check correctness of adjustment of the regulator of pressure.

Adjustment of the regulator needs to be carried out also after replacement of springs of a back suspension bracket and repair of the regulator of pressure.
