The valve sensitive to loading/perepusknoj (LSP and BP)

The centre of gravity of lorries is located above, than at automobile, besides, on the unloaded car it is considerably shifted forward. During braking the combination of the listed factors leads to that the basic loading is necessary on forward wheels while back considerably unload. Thus, hydraulic pressure in a forward brake contour should be appreciable above, than in back (otherwise back wheels at sharp braking will be blocked prematurely).

At loading the truck centre of gravity is displaced in its back part that demands corresponding redistribution of brake efforts. The given function is carried out by the valve sensitive to loading/perepusknoj (LSP and BP) (address to an accompanying illustration).

In view of that for adjustment and service LSP and BP the special measuring equipment is required, it is necessary to charge performance of the given work to experts of car-care centre. Nevertheless, valve replacement can be quite made own forces of the owner of the car (for adjustment LSP and BP the car nevertheless should be driven away on a 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 road gleam LSP and BP (if other installations of the valve did not change the rod detachment should not lead to infringement of adjustments).

3. Give a counternut and disconnect an adjusting bolt from the lever of a back suspension bracket.
4. Turn out fixing bolts and remove valve LSP and BP in gathering with the basic arm.
5. Give fixing nuts and remove клапанную assemblage from a basic arm.
6. Installation is made upside-down. Track correctness of installation of initial length of a spring and reliability of a tightening of a counternut (address
To an accompanying illustration).
