Dear Forum Members:

This is my first post here. I don't have a Nissan anymore, but I had 510 when I was in my early twenties. Do I ever miss that car...

I would like to solicit your expertise in Japanese brake master cylinders. I am rebuilding a 1973 Triumph GT6 MkIII for my wife. Master cylinders are not available anymore. Some previous owner installed a Nabco master (photos attached) with a remote reservoir. I think it was a good move, but I received the car in February and although the brakes were fine before the journey from Dallas - it arrived in Canada in severe weather conditions (-30 F). The change in weather killed the brake seals in the car and brake fluid was everywhere.







It looks like an excellent MC and I would like to keep it, but I can't rebuild it until I identify it in order to purchase new parts. It is indicated NABCO, 7/8 (bore size for sure) and has all the inlets and outlets on the same side, same plane.

Please take a look and see if you can tell which car it was OEM equipment on. Any help you may provide will be a huge help. Feel free to offer any other advice in regards to rebuilding this master cylinder as you see fit. If you think this post fits best in an other forum, please suggest...

Many thanks in advance...

Dave the Brake Mechanic,

Looks like your generic Nabco Brake MC from a late model Z modified, as you explain, with the remote reservoir. They all use the same MC, just need to insure you get the 7/8 in rebuild kit vis the 3/4 in kit.

These kits are pretty common and come as seals/O-rings only or complete kit with piston with seals, spring, boot, and washers.

Your local parts store should be able to get you the kit for a 7/8 in bore or Black Dragoon or eBay has them. I would definitely check on line and look at the schematics or mechanical drawings to insure you ID the correct kit needed as they look pretty similar from the outside. Here's the link to Black Dragoon's MC page -

Notice the difference in the piston for the '72-78 Z's and the 82-83 ZX.

If you are interested in going back to the original AP or Lockheed (or whatever Triumph was sent by British Leyland) Victoria British has dual set up for $199.99 or $219.99 depending on your model -

I have to return a few parts later this week and can check on any specific part or get you specs or pics, at VB, just let me know.
