Sensitive to loading / перепускной valve (LSP & BP)

The center of gravity of trucks is located above, than at automobile, besides, on the unloaded car it considerably is shifted forward. During braking the combination of the listed factors leads to the fact that the main loading is the share of forward wheels while back considerably unload. Thus, hydraulic pressure in a forward brake contour has to be much higher, than in back (otherwise back wheels at sharp braking will be prematurely blocked).

When loading the center of gravity of the truck is displaced in its back part that demands the corresponding redistribution of brake efforts. Performs this function sensitive to loading / перепускной the valve (LSP & BP) (address an accompanying illustration).

In view of that adjustment and service of LSP & BP requires the special measuring equipment, performance of this work should be charged to specialists of car service. Nevertheless, replacement of the valve can be quite made by own forces of the owner of the car (for adjustment of LSP & BP the car nevertheless should be driven away on car repair shop). At removal of the back bridge it is necessary also not to forget to disconnect from it a rod of monitoring of a road gleam of LSP & BP (if other installations of the valve did not change, then the detachment of a rod should not lead to violation of adjustments).
