So im leaving work today and press the back brakes, nothing....pressed again, nothing...So i stopped and got off. Pushed the bike back and forth a couple times, all the sudden i have rear brakes again. WTF? Any ideas this one has me totally stumped.

 

Bad fluid, got hot and lost pressure, maybe a bolt loose in the mount for the pedal and didnt engage all the way ??? Just guessing here.

 

You gotta be more specific. Was there any pressure on the pedal or did it depress with no resistance?

 

Could be vapour lock, could be your Master Cylinder saying Ta ta, regardless have your brakes checked out before you ride it again. You don't realise how much you need the brakes till they ain't there.

 

If you have no fluid leak your rottor or wheel is not out of line(vibrating) knocking the pads back into the caliper. I would make sure your axle is tightBEFORE you ride it!

 

check all of the above. personally, I suspect its bad fluid, or the master going out.

 

Again all the above, and probably the least likely problem, but could be a defect inside the hose (seen it a few times on cars).

 

Brakes?! We don't need no stink'n brakes!

 

brakes what brakes

they are so over rated....kind like gas who needs it any how

 

compression braking ftw....well...not really..but it sounded good
