    1954 -- source for rear wheel cylinder "banjo bolt"?

    I've been chasing silicone brake fluid leaks on my '54. I've put silicone fluid in some of my past collector cars and never had so much trouble stopping the leaks. Well, the banjo bolt on the right rear wheel cylinder finally got tightened enough to twist its head off (and the silicone leak hadn't yet stopped). (The banjo bolt is a drilled bolt that allows brake fluid to flow between the wheel cylinder and the attached brass block through the hole in the bolt; it also holds the brass block to the wheel cylinder.) I don't see the bolt listed in any of the usual Corvette parts supplier catalogs. Anyone know where I can get a replacement? Unfortunately, the car is "grounded" until I find one.

    Thanks,

    Pete

      Just to close out this thread, I tried the link Clem suggested and they didn't have the right size. I removed my old one in two pieces and measured it. It is 7/16"-20 x 1-1/8" (although that length might be a little stretched from yield prior to breaking). Armed with the term "banjo," as this is a "banjo bolt," I was able to locate some close alternatives at local chain auto stores, although they will have to order from their warehouse. I finally settled on NAPA part #82702, which is 7/16"-20 x 1-3/16", figuring I could grind or cut it a little shorter to make it a perfect fit. It appears to have the right head size and shape, as well, so should look reasonably original externally.

          1938-55 chevrolet brake hose bolt #476099, 7/16"x 20x 1 1/16". i have purchased NOS bolts from Mega Parts in Coon Valley, Wi. Also a 7/16x20x1.18" bolt can be found on ebay. all newer bolts appear to be stainless. a NOS bolt will be common steel and the flats on the head will have two indentations on each corner of the flats.

            Thanks for the part number, John. I just ordered one from Chev's of the 40s. I'll pass on the NAPA bolt after all, and use this one when it arrives.
