I'm using sierra disks fronnt and rear and am struggling to find a suitable sierra master cylinder.

are there any other 'Donor' master cylinders that are more readlily available that will have the right capacity to opperate my sierra brake set up?

Thanks

Is it worth messing about with an old, unknown master cylinder?

For peace of mind (and they are not that expensive) I would buy a new one - but it's your neck

I've fitted a mondeo master cylinder on my tiger. Running discs all rould not had any probs so far, but it aint on the road yet.
