banshee front brake resevoir

[sand4ever]

i had my front brake resevoir polished and now It leaks where the brake line connect to it. It seems they rolled an edge where the copper washer connects to the resevoir. Any one have an idea to stop the leak. I'm trying to bleed the brakes and of course this cannot be done until the leak it fixed. Can i use silicone? Also I'm using steel braided lines. Two individual lines to the calipers.

I had the same problem. Using silicone WILL NOT seal it. Your brake lines are under tremendous pressure when you pull your lever.

I had to stick mine in my mill with a 10mm drill rod in the port. I used that to properly align it, and get it square in the vise. Then I took a .500 endmill, and spot faced it. Worked great after that, and I learned a lesson on polishing shit.

So I should take it to a machine shop and have them mill it flat? Is that what you meant?

Yes and no.

You do want it flat. That is for sure. But, it MUST be perpendicular to the bolt, or when you tighten your bolt down, it won't seal because the surface is out of square.

I thought of another way to get it aligned that would workout just as well as using a dowel. Tell the machine shop to use a 10mm tap, screw it into the ressy, put the whole thing in a chuck, and that will ensure the ressy is square and not tipped.
