bleeding harley brakes tip.
I have found that the bleeding process itself can introduce residual crap into a very small return hole in the bottom of the brake fluid master cylinder.
Try using a wet/dry vacume with a home made attachment to suck out the entire master cylinder and the offending small return hole .
Rebleed the system and hopefully this will be the fix.?

I wonder did you suck anything out of the return hole at the bottom of the master cylinder?

That happens every time I replace pads or remove my front wheel. I usually end up pushing the caliper pistons back into the caliper in the process and they need to be returned to the extended position. No need to bleed the brakes but, rapidly pump the lever until some resistance is felt. This may only be at 1/2 travel but, hold for about 5 seconds then repeat the pump and hold process until the lever gets firm. Works everytime for the last 20 years.
