Help! Brake Master Cylinder

[zak_62]

The brake master cylinder is leaking on my '87 Turbo Esprit.
I took it apart and take it to a machine shop to refinish the inner cylinder surface, but the surface is in bad shape and we are not able to get the cylinder unit properly sealed up. I called up SJ and he said that these are out of production and he can't find any more of them. What should I do? Is there any other unit you are experienced of that can be modified to fit a G-Type Turbo Esprit?
Thanks for the tips

First... try JAE. They have always been a good source of info for me and often have parts that are no longer available as they started manufacturing some of these parts a couple years ago at their machine shop.

However, if that does not turn up anything, I have seen two other options:

First (and not my favorite option), I have seen a Porsche 911 master used. It does however require some fiddling with as it will put too much bias rearward. Like I said, not my favorite solution...

Second (and I preffer this), take your original master to a machine shop and have the cylinder bored out larger by a mm or so. Then, have them make an aliminum sleeve based on the measurments they take of the cylinder bore (once bored out). The sleeve should be a hair larger in diameter. The shop can then freeze the sleeve, warm up the master cyclinder, and press the sleeve into the master cylinder. Drill into the sleeve once installed through the line attachement holes from the outside to insure the correct alignment.

Of course, the sleeve inner diameter should match the original inner diameter of the master cylinder.

A good bit of work for the machine shop, but they should not have a problem doing this. Hopefully the part can be located by JAE.

Good luck,

Check out White Post restorations. They sleeved the master cylinder for my '57 Chevy. You can find them in every issue of Hemmings Motor News or online. The also reconditioned the exterior such that it looked brand new.

If you have no luck finding a new replacement, then sleeving the bore is a valid alternative. Look for a company that's into vintage automotive restorations. Even if they don't sleeve hydraulic cylinders themselves, they may be able to point you toward companies that do.

In the USA, the following companies sleeve and rebuild automotive brake and clutch cylinders. Apple even keeps an inventory on the shelf and can do business on an exchange basis to cut turn-around time to a minimum.

Apple and White Post use brass sleeves. Stainless uses (what else ?) stainless steel sleeves.

Thanks for the tips, I will talk to my local shops here in Taiwan about the sleeving options.

Doesn't the Master Cylinder cross over to Triumph?
