52 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 “ H ” 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.
