6.1.4 LOAD SENSING PROPORTIONATING
VALVE
(LSPV) (
FOR NON ABS VEHICLE
ONLY)
GENERAL DESCRIPTION
LSPV is required in the braking system during
severe braking. At the time of severe braking most
of the vehicle weight is transferred to the front and
front brake does most of the braking. Rear wheels
are left with little traction and in this high pressure
condition rear wheels have tendency to skid.
The LSPV valve is installed on the chassis and
load sensing spring is connected to the rear axle
at the other end. During heavy braking the valve
limits the pressure to the rear wheels and this
allows rear wheels to continue to rotate instead of
locking and skidding.

the rear axle.
REMOVAL
