BRAKES

LOAD CONSCIOUS PRESSURE REDUCING

VALVE (LCRV)

A LCRV is required in the brake system during

severe braking. That time, most of the car weight is

transferred to the front, and the front brakes do most

of the braking. The rear wheels are left with but little

traction and in this condition, under high pressure,

they have a tendency to skid.

The valve is installed in the line to the rear brake

drum. During heavy braking the valves limits the

pressure to the rear wheels & this allows rear wheels

to keep turning instead of locking up and skidding.

REMOVAL OF LCRV

Unscrew and remove hex. nut holding LCRV linkage

with mounting bracket on rear axle.

Unscrew and remove hex. screws holding LCRV with

mounting, bracket on frame. Remove LCRV

assembly.

INSTALLATION OF LCRV

Position LCRV on mounting bracket at frame. Fit

hex. screws, and hex. nuts. Tighten screws to 2.1 -

2.5 mkg. torque.

Fit link end on mounting bracket at rear axle with

spring washer and hex. nut (M8 x 1.25). Tighten

hex. nut to torque of 1.1 to 1.4 mkg.

ADJUSTMENT: VALVE SETTING METHOD -

With link ‘C’ in hole ‘B’ and vehicle in unladen

condition, set the gap “

” between valve piston stem

& adjusting screw to 1.0 to 1.2 mm as shown in

(Fig. 54) with the help of adjusting screw and locknut.

Tighten locknut of adjusting screw. Then engage the

link ‘C’ in hole ‘A’ i.e. upper hole of the bracket.
