What are you planning to go with on your ERA?

Girlings. Until they leak, and then ???

Since I'm a little way behind you Evan, I will be watching this. I sure like the idea of the Girlings, but hate the idea of brake fluid eating into the finishes of everything below them.

We can help with that a little (the "we" includes patrickt). The fluid cans have a nipple on the bottom with a compression fitting. They need to be taken apart and sealed with a brake resistant sealer when reassembled. Here is a thread patrickt started on this.

Brake Fluid Resistant Sealant for Girling Reservoirs

I believe I used a different sealer but as long as it's fuel/brake resistant it should work.

Next step is to buy brake cylinder cap gaskets for a closed system. Patrick wrote about this somewhere too but I couldn't locate it. Here is what you will need.



These will gasket the cap to prevent a leak and have the inner bellows that follows any drop in fluid level.

The 3rd step that ERAChase passed along was to double clamp the rubber hoses to the metal lines, orienting the two clamps 180 degrees apart. Here is a picture.



And 4th - don't fill the reservoirs much over about half full. They are small but significant fluid is also in the long lines down to the master cylinder. I've seen larger (longer) cans but ERA provided the standard smaller ones. I'm not sure what size was actually used on the S/C cars. I've seen pictures with the large cans for the brakes and the standard can for the clutch. And I've seen pictures with standard cans for all three. It's good practice to check the fluid level every few months. Mine have been on for about 5 years now and are leak free (knock on my head (wood)). Still, I often run a finger around the bottom and along the lines just to make sure they are staying that way.

Girling Reservoirs have improved since I had mine put on (and since I sealed them up). These from Moss Motors are much better made than even the originals, much less the replicas: https://mossmotors.com/tank-assembly-single-supply
