Well, having removed the throttle (my last post...), I got the master cylinder off, and if I fill the reservoir and squeeze the lever, nothing happens. No fluid moves through it. Which would explain the difficulty in bleeding the brakes I've been experiencing. I read through the shop manual I found on here, and the step to disassemble the master cylinder references a specialty tool used to press the internals out. Anyone ever torn theirs down before? Have any tips for getting the inside bits to make their way outside?
