This creates a small problem in that Jasons small extension has to be made to marry up the two operating faces between the servo and the m/c.
But...............for those of us who have remote reservoirs, if this new plate was not fitted and the m/c was fitted direct to the servo the new plate would not be needed and the servo and m/c faces should marry up ( more or less )
Are you still with me or is this gobbledygook ?
Hi Dennis
The new servo is American, and designed for great big master cylinders with great big flanges, with great big holes and a great big diameter. The fixings are also set either North-South, or East-West.
The European Ford and BMW car master cylinders are both much smaller. The flanges are not big enough to fit directly on to the new servo fixing posts, and do not align North - South, or East-West, but 22 degrees offset - hence the need for the adaptor plate - to allow the fixing posts to be brought in to a smaller diameter, rotated 22 degrees, and reduced in size (from 10mm to 8mm)
All will become obvious when you offer a car master cylinder up to your new servo. Pictures alone are sometimes misleading.

Unless you have a master cylinder with a great big flange and great big holes and .............?

Mike
