Thanx for the reply!
front brakes; Yes oil is not a good sign. I was thinking that the oil came
from the front forks that where leaking before (now fixed).
Now it seems I was wrong.
Agreed! Brake system is THE most important part of a bike so I just have
to start tear the brakes apart to find out whats wrong with them.
However, what can be wrong with it if itīs not (only) the seals?
