250r Rear Caliper for 400ex?
#1
I'm starting to really think about swaping out the Rear Caliper from a 250r onto my 400ex. I want to go to the twin-piston setup for stronger braking and improved pad life due to almost twice the braking surface area. I'm pretty confident I can fabricate the mount (if needed), but my main concern is the rear master cylinder. Will it have enough power to push the two pistons? Is the 250r unit a stronger pump? If it is i'll switch over to that too.
