The other day I got some spangly new M615s. One of them is fine but the other one has a leak. If I pull the lever and hold it, after a few seconds fluid starts to appear around the exposed threads of the hose connector at the lever end. If I hold the brake on the lever goes back to the bar.
...the hose is too long and I need to shorten it. Should I take a chance and assume the leak is from a badly fitted connector that I'm going to cut off anyway or simply send the brake back?
