Did anyone ever find a definitive solution to the stiff pedal? The 4 piston Viper calipers and braided lines on the front of my 99 made the pedal too stiff and I was going to order the RAYBESTOS MC390508 master cylinder that's advertised as 15/16" bore but It's kind of a crap shoot if it's actually the smaller bore diameter and if it'll give a better pedal feel.
