Asking the pros here if Barndoors used this metal type reservoir? If so what years. Early split window bugs did.

Wed Jan 22, 2014 10:21 am

Yes. All years, unless I am not aware the super early Barndoors are different.

It extended into non-Barndoors too.

Progressive Refinements says:
11 Apr. 1957
Chassis # 248 322
Brake Fluid Reservoir
Now: rubber cap
Formerly: Screwed cover

Now: screwed flange, 19mm
Formerly: 27mm

Awesome! Thanks Everette!

Do these early numbers mean anything? At one end what I think is a number 16? The outer diameter of master cylinder is smaller compared to an August 55 master cylinder.
Is there a thread somewhere pointing out the differences in years?

Usually that number is the diameter of the master cylinder.

For instance 19 or 22 meaning 19mm or 22mm.

Barndoors are 19mm, 55-67 are 22mm.

16 is for ?

And very early barndoors are 22mm

this simply must be a 16mm master. probably out of some other German car brand, maybe DkW, Cologne Ford or similar. They must have used the same standard reservoir on different size cylinders, which they also did later and still do, although nowadays the standard classic car reservoir is made of plastic of course.

Thank you Tonny.

I also assume the very early reservoirs might be steel instead of aluminum?

The remains on both my 52 and 51 were steel I think, I had assumed that the one in the pic above was steel (zinc plated) too as it looks rusty on a few spots on the side of it?

Steel one are 1952 and down bug and bus

That's the info I found in the spit window bug threads.. I'm thinking what Everette found was for the aluminum canisters.

Yes, for sure steel. The same as on a early beetle

That looks curved at the bottom.
This reservoir was on my Jan '56 westy when I got it:

The same type was on my June '53 bus when I got it, and it had '66 tags on at the time.
You can't see it very well:

Yes. Mine does appear to be more round at the bottom.

Here's the bottom stamping just like what you have. The reservoir is definitely Ate. The Ate cap fits perfect. It could be an earlier or older version.

What are people using for reservoir gaskets 24 and 27?

Ie who supplies these?
Are they rubber, or the fibre type?

(Ref gasket 27…is that internal diameter 22mm, external diameter 27mm?)

Thu Sep 22, 2022 10:48 am

I actually have gasket 27…it’s a copper ring, approx 22/27 diameters.

So would like to know about gasket 24…and gasket 25 come to think of it

Still unsure what material gasket #25 is.

RockStock wrote: #24 Rubber Seal

Please can someone post up the internal and external diameter of rubber seal #24?

Wed Mar 08, 2023 12:43 pm

Inner diameter is 50 millimeters.

Outer diameter is 66.5 millimeters.

Thickness is 1.2 millimeters.

Thank you Crashbox! Very kind.
Does anyone have a spare seal?
