The pedal just drops to the floor but i still have a little brakes which allow me to stop over a long distance. no mo ridin othere peoples bumpers. I bled the system twice properly before i even changed out the MC and also monitored the fluid level for months as this problem got worse. There was no fluid loss whatsoever. After i changed out the mc i bled the brakes twice also and it seemed to work well for a week and then it happened again. No fluid leaking and no air in the lines. They function just fine most of the time and then randomly the pedal goes to the floor with no resistance. I just cant understand how the brakes can work just fine and out of the blue do thi, then work just fine at the next stop! gremlins i tell ya! or maybe the underwear knomes.
