LSPV assembly (the regulator of brake forces of a back axis if is)

As shown in the drawing below, LSPV is a part of the brake chain connecting the main cylinder and a brake of a back wheel. It controls the hydraulic pressure enclosed to a brake of a back wheel depending on the loaded condition of the vehicle (or loading weight), thereby without allowing back wheels to be blocked prematurely. Besides, she removes management over the hydraulic pressure enclosed to a brake of back wheels in case of any malfunctions in a hydraulic actuator of a brake of forward wheels so the hydraulic pressure created in the main cylinder is put directly to a brake of back wheels to operate it.

1 — LSPV
2 — the LSPV lever
3 — a spring

4 — LSPV is resistant
