Hi there.
I have a Gas Gas EC250. Great bike.
The front brake is really spongy. changed pistons, seals fluid bled em down an bled em back and they still aint doing it for me. Oh and ive changed the wheel bearings just in case the wheel was deflecting. Disc is true too.
The bike still stops really well but there is no feel at the lever.
My next step is a master cylinder kit but does anybody have any experience with this problem?
