something to try before you install the proportioning valve ,, if you have access to pressure gauges for brakes ,put one the front ,one on the back apply pedal pressure and read gauges ,,if its higher on the rear install on the rear ,,higher on the front maybe you don't need one or install on the front ,, my calipers are the same size on front and rear ,I put mine on the rear line gmonde
