sticky clutch - United Bimmer Community

so I pinned it off the lights to day and my clutch stuck to the floor. WTF. And it stayed down until I braked. I have never experienced anything like this before.
anyone ever have this happen to them?

Assuming you don't have air in your lines, you might have a faulty master cylinder. The fluid is probably leaking past the plunger in the cylinder. The pedal stays down because it takes time for the fluid to exit the back side of the plunger and flow back through. Braking can speed up or affect the process because they share the same fluid reservoir. When you launched, did you hold the clutch in longer than usual? That would account for it not happening as often; a typical shift may not be enough time for the fluid to leak through to the wrong side.

Is it going to get worse? And if so is there a way to fix it or do I have to replace the master cylinder?

if there is all of a sudden air in your brakes, you probably have a leak, lets hope its in the lines, not the master cylinder, however check your brake fluid, see if its low, then go from there
