Works for me.

Which one Vic.....the can for a reservoir or being a "tightass"?? LOL

Nice one Jim. I've seen a plastic cheese spread container pressed into use as well. In Wisconsin of course.

Btw, if anyone wants to keep originality, the old aluminum ones can be repaired. The tiny pinholes that develop at the interface between the aluminum can and steel master cylinder can be TIG welded and ground flush. Good as new.

JB Weld does wonders!

Stirring this thread back to life. Where can you buy an aluminum reservoir of the correct style? The one with the ridge on top, pictured to the right in Mario's first post.

See the classifieds today for one of the two versions of the alum reservoir : The Flat Top vs The Ridge Top.

Thanks Brad!

A fortuitous coincidence today: I saw the next step in my 24-years dormant 1962 car stirring back to life (my mechanic is doing a brake job) and I looked at the classifieds and saw the aluminum reservoir from 356 Devotion. My mechanic has installed the plastic reservoir. I wondered which is correct, so I searched and found this recent thread.

The one from 356 Devotion has a flat top. Posters here say that I should have a ridge top. The brakes will probably fail if I use the wrong top

Here's where we ended up on our car.....

Mario, where did you find that correct reservoir? In your stash or from a vendor?

Stash.....and help from Deluxe Customs in Tempe, AZ, Matt Howard cleaned it up beautifully.

I wish a vendor made one, but seems the only one being made is the flat top one sold by 356 Devotion.

The price of old Calumet baking powder cans just skyrocketed...

The reason that the aluminium cans rot is that they are in contact with the ferrous reservoir. Hierarchy of metals. Two dissimilar metals in the proximity of an electrolyte. I think an insulating gasket might help, also using silicone brake fluid might help. But really, someone should be making a new aluminum can with thicker walls, or zinc plated steel that looks like an old aluminium can.

Did these original aluminum reservoir cans utilize a plastic/nylon/other strainer under the cap such as was used on the plastic reservoirs?
