MG TD TF 1500 - Seeking ORIGINAL Lockheed MC check valve

My project for this winter, is to rebuild my Master Cylinder. I re-built it two years ago using a kit that obviously had inferior parts in it, as it failed late last summer. I bought this kit from a well-known supplier, but it wasn’t original Lockheed, and seemed to come from Asia.

Recently, I was able to locate two original Lockheed kits ($47 ea). Both had been opened, and both are missing the all-critical hat-like stainless residual pressure check valve - OEM 7H488, Moss 180-045; and now almost impossible to locate individually, if at all.

Today’s replacement for this part, is now in plastic, and I feel that is what failed on my MC.

If anybody knows where I can buy (just) this original Lockheed valve, I would be very grateful; otherwise, I’m going to see if I can source it in the UK, OZ or NZ

Hi
I have several NOS kits for sale. They also do not have the part you need. I do not think they came in the kit. I have a spare used one if you still need it.

I have several thousand of T Type parts surplus to my need if you need other items.

Thanks Gary but I have 2 new kits, for which I paid a larcenous price, especially considering that they were missing the key part.

The metal part was never supplied with the Lockheed kit, only the rubber insert. Neither of your original kits is incomplete.

The Vanguard brand of rebuild kit from the 50's did include the top hat, and there is one on eBay right now - with an original master cylinder - for $39.95. Here's the link:

Thanks Tom. I didn't move fast enough. Its gone!. I actually have 3 or 4 used Master Cylinders, in various state of decay. If I can't scrounge one overseas, I'll have to use what I have.

Hi Gord
Did you get my Email on the small metal part you need. I have a used one if that will work.

Yes Gary. I did , and I replied. I have a couple of used ones, but I'm really aiming to get find a Lockheed kit with a new one in it. Contrary to Tom Lange, the kits I bought did indeed have the stainless excess-pressure relief valve.

I'll rebuild with a used one before going back to the plastic.

Gord - kits must differ. I pulled three un-opened NOS Lockheed kits from the shelf, two early and one later, and all have the rubber insert; none has the metal piece. It's not a wear item, so I am not sure why Lockheed would supply it in the rebuild kit.

Perhaps, at different times, Lockheed provided different kits?
