Do I need new brake reservoirs?

[FIA-ERA]

I ended up making my own seals a little larger than the seals I got, cut a U shape slit in them away from the center cap hole, then stuffed the seal into the cap. The result was a tighter fit but as I stated I left residue on the threads and when that got hot it ran down and stated eating paint.

I finally said "enough!" and went with the Kirkham cans. Didn't use their bracket. I will powder coat the old ones and buy the Girling labels for them for later. But, for everyday driving and use you can't beat his cans. the added benefit is that they come with Willwood caps and I can use my Power Bleeder without worrying about blowing up the tin cans! I can change out my brake / clutch fluids in about 10-15 minutes max!! Sometimes, for me anyways, modern technology can be a good thing....
