Is a residual pressure valve necessary in either the front or rear circuit on a disc/disc setup? I got a used rear disc setup that has a 2# rpv in the rear circuit. I've read conflicting views about this..
I run a 2# on front and rear if disc and 10# on rear if drum. I can't see a drawback unless you have excess draging... Most time when we try and eliminate the rpv you need to pump the pedal once to get the hard pedal...
