A friend gave me a 19mm Nissin from his Chaotic is an idjit... (it is the post warranty model). i tried using it on my SV but could barely get any fluid to come out of the outlet and the brakes never would bleed properly. Figured it needed a rebuild so I did that today. Nothing seemed clogged or worn. It still barely has any fluid come out when i pump and only occasionally. Also with the lever all the way out, no fluid drips from the outlet or bleeder (which I thought they are supposed to do). i ended up putting a Brembo on my SV and it bled and worked fine. I checked the hole in the body where the resovoir connects and it seems clear. Any thoughts? Thanks!
