I've crashed hard, handlebar rotated as much as it could and I guess rear brake cable was stretched. Braking became soft. Time to bleed I thought.
But I'm completely unable to bleed it. Tried some many times w/o any success.
To test my bleeding techniques I've rebleed other (front) brakes - everything is fine. Even tried to push air first and then fix it by rebleeding. Works perfect.
Then I've tried to move parts of working brakes to non-working brakes and bleeding each time. Turned out that the fail point is cable (hose).
However I don't see any leaks or damages. At all.
Brakes: Avid Elixir 3 and it uses DOT fluid.
Is that possible for the cable to have some sort of invisible internal leak?
