Hi all ,we've just replaced all the calipers,discs,brake pipes on the wifes 110(thats right "the wifes").The problem we have,having bled the system four times is that the pedal is good when the engine isn't running,however when you start it up and leave it running for five minutes the pedal travels about halfway down,it,s the same when you drive down the road about a mile after the pedal was last used.There are no leaks and no air bubble's in the system.Any idea's anyone?.Thank's Paul.[ZE]
