Well, after some time, I've finally got the replacement rear brake line in. I will say that most of the stories you hear about replacing that back brake line are true. . . but that's a different discussion. I'm ready to bleed out the lines, and have a couple simple questions: First, what size are the bleeders? I tried all the SAE size tube wrenches I've got and they all felt like they were a tad too large. I got out one of my deep metric sockets, and that seemed to fit, but I couldn't budge the bleeder. Second, how likely is the bleeder to break when I try to get it out? I'm concerned that something may break off when trying to open the bleeder. Is this going to be a problem, or am I being over pessimistic? If it does break, how do I get the remaining part(s) out? Easy-outs? And finally, I've used the MityVac bleeders(and their many clones) several times before, and intend to get one again for this job, but thought I'd ask if there are any better, not super expensive, options before getting one. Unfortunately, this has to be a one-man job, no one around to help bleed. As always, TIA.
