Writing on the adjustment knob refers to "Less Brake", is this referring to the rear drum brakes ?

do you install this valve before or after the stop light switch?

Part number 91031353 Normally the stop light switch is installed close to the master cylinder but not a definite requirement. The proportioning valve can be installed before or after and in either case will still allow the switch to operate properly.
