Wanted '59 TR3A Clutch Master Cylinder - USED, RE-BUILDABLE, NOS


Looking for a clutch master cylinder to replace one that failed recently.

The cylinder should look like this

original MC during restoration, photos from recent eBay ad (UK supplier)

and NOT like this

Any leads on a replacement MC would be appreciated.:smile:

Is this the supplier? Picture shows correct cylinder.

I think I have a used one but there are several bore sizes. Will see if I can find it and measure the bore.

By the way, the adapter fitting on the new repros comes out and the pipe goes right in without it or at least it did on the one I replaced several years ago. You can't do much about the reinforcing tab cast into the housing.

This might be what I was thinking of. Probably of no use to you as it has the reinforcing fin. It is also 7/8 bore, which is incorrect for the TR3.
