Can't flush any fluid through rear brake line? Help!
Hi one and all -
Recently bought a 2000 650c, and need to do a bunch of work on it to get it roadworthy. I did the fork seals yesterday, today wanted to get the rear brake working. There was no brake feel whatsoever so my first step was to bleed the system. Attached some hose onto the bleed valve, pumped the pedal, held it down, cracked the valve and closed it again.
Repeat for over an hour...
About an inch of very dark (almost black) fluid came into the hose, that's it. Figured there was a blockage somewhere - unscrewed the bleed valve completely, pumped the pedal - nothing. No fluid came out at all.
Then tried loosening the banjo bolt on the caliper - no fluid came out of that, or the caliper.
Removed the brake line completely, tried blowing some air down there and it seems to be ok, unblocked.
I have no idea what to try next. Pumping the brake pedal has no effect at all, and whatever fluid is in the system is black as the ace of spades.
Any help would be very gratefully received!
