[Healeys] brake servo parts

[Jean Caron]

Simon,

Not sure where you are located but there must be a place in your area that sells "O" rings. Go there and ask for "O" rings that can be subjected to constant exposure to brake fluid, bring an old one with you so they can have the right size for you. You should not use the "O" rings that you can get at places like Home Depot etc. they will not be suitable for your application. There is a place where I live that has all types of "O" rings, you just need to mention the application, like oil, or fuel etc and they should be able to help you.

Look, I haven't played with a Lockheed Servo in years but my initial response was to suggest that you buy a box of different size "O-rings". We get them over here anyhow....a plastic box about 5" by 3" with little compartments filled with different sized rings. Costs nothing and the contents will keep you going forever. And there will be a ring in there that fits. And they are probably on eBay. BUT, BUT, will an ordinary O-ring survive in brake fluid? I don't know, but I do know that I put in a Girling rebuild kit once which worked fine for a while and then gave up. There was no warning, no gradual process. I nearly hit a wall. One of the little nylony/rubbery things had turned itself into something with the same consistency and usefulness as a ten year old tea bag. It didn't like brake fluid and it dissolved.

A few enquiries of the right people should see you right....

Hi,



I am looking for a source for the 4 small O-rings that go on the air valve piston on the Lockheed brake booster for my BJ8.



Just to make sure I described the part correctly, the air valve piston  is #5 at http://www.v8register.net/FilesV8WN/Brake%20servo%20working%20note%20190109.pdf, or the "reaction piston" at http://www.triumph-spitfire.nl/servoimages.htm.

I took the whole thing apart last winter, and everything looks like it's in good shape, so I don't need to replace the whole booster or get a re-build kit from Moss, just looking for 4 O-rings.



thanks,



Tom
