Fail story. Did I mess up my brake?
I was trying to troubleshoot a resonance/squeal from a Magura MT4 back disc break. So I did what everyone with time to spare does: I watched a Youtube video of a guy straightening his break by loosening two screws on the disc break, and then pressing the break in order to 'align' it, before tightening it. So I did that. Unfortunately in my utter noobidity, I loosened the screw which apparently holds the break fluid. So when I pressed the break to 'align it', it ended up squeezing a couple drops of fluid out. In my horror I tightened the bolt again, cleaned up the break and forbid myself from messing with it further... However now I can feel that the break is a bit 'gritty' at the bottom out. Can you tell me:
1) did I mess up the break or is it kind of fine? Do I need to bleed it now?
2) is this 'grittyness' an imagination? Are the two breaks, left and right, supposed to feel identical?
