The Orange Illustrated Parts book from the factory (1975) calls te cylinder 
a 'brake pressure control', and there were at least three versions- one of 
which was adjustable (per the Black Illlustrated Parts book-1985)- just like 
a commonly-referred-to "brake proportioning valve" . But regardless of what 
you call it, it limits the force one can apply to the front calipers with 
the brake pedal. Removing it increases the pedal force applied to the front 
rotors, increasing the stopping force at any pedal pressure since you don't 
have to first overcome the strength of the coil spring inside the valve. 

And no- you won't need a proportioning valve if you DECREASE the brake 
force on the rear rotors (by removing the extra calipers). Only if you INCREASE 
the force applied to the rear rotors, will a proprotioning valve possibly be 
needed to prevent rear lock-up. Good luck- J DeRyke
