Pushing Brake Fluid

Question for Fix My Hog 2004 Harley Davidson Heritage. I viewed your video concerning brake bleeding and really like the idea of pushing brake fluid through the system rather than sucking it out, it makes a whole lot of sense with regard to air bubbles. Several months ago I purchased a Phoenix injector system and like what it does, however, when bleeding the brakes I just can’t quite get a firm brake lever and I am striving towards the firmest brake lever possible. I have watched the videos time and time again and can’t get that firm brake lever, and after I’ve used the Phoenix injector, I sucked the air out in the other direction. Would you have any more possible tips or what I may be doing wrong?

Fix My Hog Answers There are 2 or 3 years that Harley was releasing motorcycles with “soft” front master cylinders. 2004 was one of those years. You can try rebuilding your master but if you had a soft lever feel before you began your work, chances are you may not be able improve the condition. These master cylinders were superseded. If you were to purchase a new master from a dealer today, you should be able to achieve the lever feel you expect.

    I had my front lever lock up. I couldn’t budge it at all. I stopped and bled down 1 side. This allowed me to get the bike home. Since then, I rebuilt both front calipers and master cylinder. I didn’t change pads, as they weren’t half worn, now I can’t get lever up. I tried bleeding old school and the tried to suck them down from the calipers. When I try and suck the fluid to caliper, it seems I am sucking air into the system. When I bleed, I get only fluid. I can pump the lever and get 1/2 of lever and it holds good pressure, so I don’t think the master is an issue. Any thoughts would be greatly appreciated.

    My 2005 FLHRCI is also soft, is that also one of the 3 years with the “soft” front master cylinder? Thanks in advance.
