HYDRAULIC BRAKES 4A-13
Construction LCRV consists of sensing part and hydraulic control part.
1. Sensing PartIt detects the changes of vehicle height caused by vehicle load. It consists of load sensing spring and control leverwhich change according to vehicle load.
2. Hydraulic Control Part It consists of valve stem devices which controls hydraulicpressure according to load detected by sensing part.
