View Full Version : What master cylinders?

06-30-2010, 4:03 PM
I'm planning to use these Japanese sport bike calipers on my shovelhead project. Would anyone know what size master cylinder is required for each?

Tokico 4 piston --> MC = ??


Tokico 6 piston (just one, not the pair) --> MC = ??

You can pretty much use whatever master you want from any modern sport bike, just make sure it fits on your bars, guessing your running 1' bars.


Are you running one on front, one on rear? If so you may be able to get away with the rear master and split the line with some long lines all the way to the front.

Yeah, 6 on the front and 4 on the rear. I've got a nissin front like the one in this pic:


and for the rear I have a small nissin like this:

I'm not real concerned about the front because I know that cylinder can drive two calipers (I'm more concerned about it being too big). The rear (I think it's only 1/2 inch) I'm not so sure about pushing the 4 pot.

Looks small but should be fine, if you notice a dramatic decrease in stopping up the resivour to a bigger size and see if it improves. You should be stopping on a fuckin dime with those calipers.
