Clutch Master

Hi, Im playing with the idea of using a motorbike rear foot brake master cyl as a clutch master.
Any input welcome.

Hmm........ might not have the capacity to open a clutch fully, my Viento uses a .75 bore master cylinder you can see it in my profile.

It's what DAX did on their ZZR1100-powered rush.

That's what I used, only because it was free with my donor ZZR1100

Due to the small bore, using a bike rear brake master should give a nice clutch pedal feel (but light) to a bike clutch. Seen it recommended sevaral times. As long as it gives enough stroke at the slave you should be fine. The mounting would be the only issue.

thanks all, I will play about in the near future and let you know how I got on

Hi as adithorp said the smaller the bore of the cylinder the easier it is to press,
sorry I did'nt realise that you were using a bike engine in your car, in that case the throw of the clutch would be less so a bike master cylinder should be ok.
