Rick Sanchez Posted September 30, 2014 Posted September 30, 2014 Hi Guys I have a set of Shimano M615 brakes. Had some trouble with the pistons sticking a bit, bit this has been fixed. But I recently started noticing a little mineral oil on the brake levers. Wiped it off a few times and it seems to come back every time.Is this normal, or is the lever leaking? Can anyone help me out on this?
David Marshall Posted October 1, 2014 Posted October 1, 2014 You will need to find out where the oil is leaking from. Could be the hose connection, the resivoir or the mechanism itself.
johanpre44 Posted October 1, 2014 Posted October 1, 2014 No problems with my M615 brakes. Did you fix the sticking pistons yourself? If it was done at an LBS maybe just take it back and ask them to look at the leak for you. I suspect that they may have bled the brakes to sort out the problem. May just be a problem with the reservoir cover and its seals not installed properly.
Rick Sanchez Posted October 1, 2014 Author Posted October 1, 2014 Taking it to the LBS tomorrow to get it checked out. Suspect it is the seals. Brakes had been bled a week ago and they barely work. Has to be leaking somehwere... BTW how far do you have to pull your levers for them to brake hard? My experience is that they dont take immediately, but only after pulling the lever some distance.
