Master cylinder issue?
I am working on a road king and having and issue with the front brakes. They stop good, but the lever pulls pretty far back before it engages the brakes. There are no fluid leaks - I replaced the fluid and bled the system thoroughly. Is this a master cylinder issue?
Again. The brakes work fine, but the lever travel is worrisome. The bike is a 2001 ( I know, a Twinkie- this by far the best section on the forum and the system looks the same as my evo)

There is a bubble that hides in the MC. "Strumming" the lever (one finger,quick snap,and snap it again as soon as it comes back - maybe at a rate of 3 per second,) and you can often get a tiny bubble to pop out of the port in the MC reservoir. Handle bar at full left lock, putting MC higher than when level.

Take a good look at the brake lines.. if poly lines, they could be expanding.. I had that issue on my rear brakes but didn't really think of it till the line actually blew out.. I replaced the entire 2 piece line and now have such a high and firm pedal like never before.. I've owned the bike for almost 20 years..
