Bought bike few weeks ago. Lots of things just weren't maintained, but nothing badly broken. The brakes were working but the rear fluid was so badly burnt brown that I figured I'd flush and bleed both. Front resivoir looked clouded over, but upon opening I discovered a fluid that was the cloudy color of clear silicone, and the viscosity was more like 90 wt gear oil. Again the brakes worked. Judging from the number of times I dumped the little bleeder bottle, I flushed about 375 ml through. That's enough for more than three full drains and refills. However, I can't build pressure now. I've pumped a couple hundred times and only clear fluid bleeds, but it just won't build pressure. Any ideas? Should I go ahead and disassemble the front caliper entirely and flush that too? I'm getting low on 600 degree Motul brake fluid, and was hoping to avoid that since it has to be ordered. I've rebuilt brakes on my WeeStrom, old Triumphs (autos), so have a clue, but this one's got me stumped. It's as if the system is sucking air in somewhere, but it isn't leaking fluid anywhere except bleed valve.
