I know where this should be, but I would like cxwrench 's input.

I have some new GRX levers and when I set them up, they were a bit too squishy for my taste. So I did what any incompetent fool would do, i.e., I funnel-bled them again with worn-down pads and the spacer, rather than the yellow bleed-block. This over-did it, and I pushed the pads apart, neglecting to open the bleed port. Out popped some brake fluid from where I assume the master cylinder is located (there is a little port or hole on the side of the lever, and appears to be aspirating a tiny bit of mineral oil when I squeeze on the lever. I don't think I am losing more pressure, but this really worries me. Did I destroy the thing?
