I have an ongoing problem and am looking for some ideas. I have an 07 Roadglide. Recently I have lost all rear brake pressure. I inspected the pads, they are still good. I checked the fluid level, it is still good and there are no leaks under the bike. I bled the rear brakes, there was no air in the fluid and I had good pressure afterwards. Within 2 hours, the pedal goes right to the floorboard? Any thoughts?

Thanks Guys

 

My opinion is you still have air in the line. Did you use a Mity Vac to bleed the brakes? The next thing I'd try would be to pump brake pedal a few times, then while holding the pedal down wrap a bungee cord around the pedal and floorboard and leave it compressed over night. If this doesn't work, then you have excessive air in the system and need to bleed it again.

 

If you have NOT done any maintenance on the rear brake system prior to this problem, then I would look at the rear break Master Cylinder. It may need a rebuild or replacement.
