Have had this problem for a few months now. Recently when I brake with my front brakes, the brake lever goes all the way to the bar..Ill drive another mile to another stop light, it will take just a flick of the lever to slow the bike down. I can pump the front brake lever and make it so it takes just a flicker every time but it will slowly decrease and eventually it will take pulling it to the bar once again.

I have bled my brakes over and over...nothing fixes the problem.

Advice?

 

If you haven't changed the fluid in a while, it could be moisture in the lines.
Even though you've tried bleeding them, you might try a complete flush and
re-fill.

It's also possible that you've developed an air leak. You can try to GENTLY
give the banjo-bolts an extra bit of torque. It's also possible to get leaks around
the bleeder-valves, as well. If you have a friend that can put their finger on the dyke.
You can pull the valves and wrap them with teflon tape and then try re-bleeding, again.

Best advice, though, DO NOT continue to ride the bike untill you get this figured out.
Sudden stops are part of the survival game, don't pull a 'Darwin'.

There are several good picture walk-throughs on complete over-hauls. If you think
you're up to it, that would be your best course. It probably could use the attention,
anyway.

Hope this helps, ern

 

sounds to me like the brake master is going out, assuming there is no leak or air in the system.

 

Mine started to do this as well. I re-bled the brakes in a hurry one day and I think I re-introduced air into the system. The other day I flushed them again and took my time. The brakes used to go flat like that while sitting in the garage so I ruled out warped rotors. I just went out and checked the pressure again as the bike has been sitting for a week without me touching it and they still felt pressurized so I'm hoping I fixed it. I've already dumped about 1200 into it this winter and would like to cap my spending there. keep us updated if you find a solution.

 

This just screams bad master cylinder.

 

+1 on the bad master cylinder. inability to hold the hydraulic pressure is bad juju

 

Also inspect your brake pads while your at it. They may need to be replaced or even have a glaze on them increasing your braking distance.
