bleeding brakes

I found I'm geeting a lot of air in the master. I took it apart again and everything looks good.Where to next?

I've never had success bleeding brakes after a flush or rebuild without using a vacuum bleeder (like a Mity Vac). You're pumping the handle, the cylinder is full of air, and it's just not doing much in the way of moving fluid down the brake lines.

Plug a vacuum bleeder on the caliper bleed nipple, pump the vacuum bleeder a few times, and it will suck the brake fluid down to the caliper, priming the master cylinder.

Sometimes I have found that removing the master from the bars(not disconecting the line) open the cap and tilting the master around to get trapped air bubbles out sometimes helps.Careful not to spill
the fluid. Good luck.

I should have mentioned that, too - if you have a fairing, cover it up with a couple towels before filling/manipulating the master cylinder. Getting brake fluid - even just a bit of it - on the ABS plastic of the fairing will cause it to weaken, crack and fail. Not right away, but after a few weeks, it will happen. Brake fluid is like poison to ABS! It will also strip paint off pretty quickly, as well.
