Tilton three-chamber MC reservoir - anyone using it?
Hey guys,
I was planning on using the Tilton three-chamber reservoir on my roadster build - it checks a number of boxes for me. Has anyone else used it for their build? Always interested in direct feedback - thanks!

I've used it in the past and planning to use on the Challenge Car build. I like it.
But, as Mr. Kleiner would say, it's a racing part and comes with things to consider. In particular no diaphragm to block moisture into the fluid.

That's great info on the lack of a diaphragm - thanks! I guess a workaround would be to run DOT 5 brake fluid.

I'm about to install that Tilton piece on my Mk5 Roadster. Have one on my Gen 3 Coupe that's been driven for five seasons. All good. Many use it as is. If you're concerned about the caps, this thread talks about installing Dorman diaphragms. I've done this mod on mine but not 100% sure it's required. https://thefactoryfiveforum.com/show...iple-Reservoir

Yes, I'm using this but the less 'tall' one and AN fittings.

Whatever you do DO NOT use DOT5.
