Did you bench bleed it?(fill it with fluid before install) this is key from my experience. Also what clutch and in the pic looks like you were using a shim for the slave, did that go back in?
On my 3650 the slave never touched the pressure plate installed (zero preload). If there is too much preload this may be a factor in why it failed so quickly.
I had to pump mine a few times each time I got in the car for the first week or so. I bench bleeded mine. Are you pumping the pedal with the vac on it? Seeing any bubbles?
Your suppose to take a few measurements before actually using that shim.
Yes, I drew a vacuum, pumped the pedal repeatively for 20-30 seconds then let it sit with the vac on it for about 5 minutes. Then repeated this a couple times.
