Here's a few pics of the 2 steel ones I have. One has been zinc plated, the other recently media blasted.

IMO: i believe there are no "ate marked" repro caps , the repro i make has no markings , and it is a clon of the cap found in my own split , no markings either , just like some nos caps being sold at the samba right now .

by last , you can buy any reservoir and cap combo you want , but beware of threadless units Laughing

..... pics will follow later today ....

here are a bunch of pics of the reservoir assembly that came with my March 13, 1951 Beetle. also pictured is the NOS cap i scored in the classifieds for $10 shipped. Dancing

i doubt the screen is correct since it doesn't really fit anywhere.

Is the res steel? That cap looks like the aftermarket NOS aluminum ones that have been everywhere lately. Good looking usable cap, but you may have corrosion problems with dissimilar metals if you use it on a steel res. Could be OK, if you put a little anti-seize compound on the threads and take it off every now and then.....

yes, reservoir is steel. unfortunately i am not a miracle worker, and i feel the original steel cap, while it still screws on, is beyond being fixable to the point where it wouldn't leak.
here is a "before" pic of the aluminum res cap. i would speculate that it is an NOS one and not a repro. i've seen a few repro caps, and this one is nicer, the logos are nice and crisp, and it is more "squared". but hey, if it is repro, it was still way cheaper than i could have bought it anywhere else.

i've pondered the corrosion/dissimilar metal situation, and i was planning on using some kind of anti-sieze on the threads. i may also have the cap anodized for additional protection.

The screw is original but the nut is just on it to hold the screen filter screw in.

and would this be the correct way for the insert to sit in the cap? I've tried this but found the brake fluid is leaking out the top. The rubber ring has softened and not giving a great seal. What's the purpose of the insert anyway? I was going to try for another seal, or for now just make one out of a gasket material to seal it all up.
thanks

after finding it wasn't the cap, I needed a way to remove the brake fluid to replace the washer between the master clyinder and the reservoir. Didn't want to bleed the brakes, and the siphons were mostly for gas tanks... this was the solution, dollar store pump worked great!

Does anybody know on what cars or buses the aluminum ATE brake reservoir on the right was used? The one on the left was used in 1953 Porsches.

As you can see, the one on the left has a standard 22 mm diameter hole for the hollow fastening bolt. The one on the right has a smaller 14 mm hole.

Anyone know anything about the one on the right?
