MG TD TF 1500 - Rebuilding Master Cylinder

In rebuilding the master cylinder for my 51 MG TD, I have misplaced the valve washer and I don't want to spend another $20-30 to get what looks like in the book a $.50 washer. Does anyone out there know the size of that washer? Is it rubber or metal? I would certainly appreciate any help that you could give me in finding/replacing that washer. The valve washer is the first washer that goes into the master cylinder. Thanks for your help.

Ed, I believe the photos below are of the washer you want. It is rubber. I rebuilt mine past year. The $20-30 bucks includes the entire MC rebuilt kit, not just that washer. Sounds like you bought the kit from Moss. Maybe they would be so kind as to just sell you the washer? Worth a try.

In any event, hope this helps. Obviously my $2 buck caliper isn't perfect, especially the thickness shot, but should be good enough?

Thickness...

ID...hard to center the caliper & shoot, so don't go 100% on this shot!
The bottom measurments are in MM by the way, not inches!

efh Haskell, thanks alot for your pictures. If I read your caliper right, the center hole is approx. 11mm, the overall size is 21mm, and the thickness is 5mm. Am I close to what you had in the pictures?

That's correct Ed. Good luck. Obviously this little guy is pretty important in stopping the vehicle so check it out good.
Fyi, I neglected to bench bleed mine after assembly and lived to regret it. It would not pump once on the car with fluid in it. I had to pull it off and bore out the cylinder a bit then fill it and bleed on the bench. I was in a "hurry" that day!
