Brake Lines, Bleeding

After replacing the whole passenger's side hard brake lines, from the master cylinder to the back drum, I went to bleed the system. Soon as we started the drivers side line in the Swiss-cheese panel and halfway through the cabin ruptured; nothing can ever go easily. So that all had to be replaced, but like I did on the passenger side I replaced the 60" single hard line from the bulkhead to cylinder with a 12 inch line from the cylinder through the firewall, connected to a 51" straight line to the Swiss-cheese panel. Once all the lines were replaced we were close to bleeding the system and hurricane Scott struck again, as he was tightening the brake-line into the drivers drum he sheared off the bleeder screw... again. So the whole drum came off, thankfully the screw had sheared in such a way that we could pretty easily get it out, then replace it.


Once all the line were in and we tightened up any places with leakage we were ready to bleed the brakes. The process took quite a while since all the lines were completely dry all the way to the back two drums. As we were bleeding Scott found a hole in the boot behind the brake pedal that was leaking brake fluid, but it was a very very slow leak that only put fluid through when the pedal was pumped. Chances are the seal underneath the boot isn't perfect, so that will have to be inspected and hopefully won't require a whole cylinder rebuild... again.
