Morning all.

Can someone confirm that the wheel cylinder diameters are the same across the range N-L - Front 22.22 and reat 19.05?

Thanks
Steve

Hi Steve,

I'm not certain but I don't thing that is true, but according to this passed expert it seems to be the better option in any case. (See the final post on the link provided).

Standard spec is 19mm all round. The R and 126 moved to 22mm front and 19mm rear to compensate for the larger engine. If you order front cylinders from most suppliers they will send you 22mm so if you want 19mm for the front you are best to order rears. As Peter has suggested the best set up is 22mm front and 19mm rear. If you go any larger than that you will need a larger master cylinder to cope with the increased fluid displacement.

Thank you both for the replies.

I was concerned about the master cylinder having to change but obviously not an issue with the 22/15 combination.

I will still have to change some of the unions as the originals into the wheel cylinders are too short - I've read somewhere about 'short' and 'long' unions.
But that's an easy fix
