Maintenance
Load conscious pressure
reducing valve (If ABS is not
fitted)
This valve is located in rear brake
circuit and regulates supply of
pressurised air to rear brake
chambers depending on the load on
rear axle.
This enables rear brake actuation
proportional to the load on rear axle
and avoids wheel locking in partially
loaded conditions.
The valve is mounted on the RH side
of the frame and connected to rear
axle with help of linkages.
Distance between axle and Chassis
top varies with the load on vehicle.
This variation is sensed by the valve
through the linkage connected to
the axle and input air pressure to
brake actuator is modulated.
Adjustment
In unladen vehicle (with or without
load body) Loosen screw 'B'. Rotate
link 'A' by sliding rubber connector
over link 'C' such that Point 'P' on
dial 'D' coincides with point 'Q'.
Tighten the screw 'B'.
Adjustment of LCRV should be done
as per valve setting data given on
the sticker, located near windshield
washer water reservoir.
