Had a problem w/ the front brakes locking up & was told by my dealer thatI should change out the brake fluid & take a look @ the piston/o-rings, etc. in the front master cyslinder. Replaced the piston/o-rings, etc. w/ a HD rebuild kit but now can't get any fluid to pump out the end of the master cylinder. The 2 small holes in the resevior are not plugged. The brake line down to the front caliper is openand fluid will flow. Anyone got any suggestions?

 

Hi dfesmire99, I had the same thing happen to my sportster after only 12000 miles on it, I did all that you did and it did not want to bleed out, on a whim I took the brake lever out and used a socket that would rest on the outside of the plunger and was able to depress the cylinder about a quarter inch more that the brake lever does, that seemed to do the trick as after a few depresses the fluid started to flow to the master cylinder in no time and I got it bled pretty quickly, I reinstalled the brake lever for the final bleeding and things went quick from there, the problem seems that the master cylinder had a trapped air pocket that normal lever usage that woud not push out, hope it works for you.
