Disma,<P>What you're looking at is called a Load Sensing Proportioning Valve (LSPV). To correct for the lift, you need to bend or modify the mechanical linkage so the linkage is on the same angle as it was before the lift. If you don't know the prior measurement, you'll have to guess.<P>Not attending to this will produce the exact result you are describing, soon followed by front brake rotors that are warped from being constantly overheated.<P>DougM
