Noticed the clutch line had a drip yesterday, this morning went to start the car and foot went down, had barely any resistance at the very bottom. Reservoir was empty. So clutch line (my bet) or slave? happy Monday!

 

I have seen leaks from the master and slave at times but the lines typically don't fail unless damaged. Refill, bleed, clean and watch for any leaks.

 

Its probably leaking from a seal, and dripping down onto the line to a low spot, so it only looks like its line leaking.

When MC leaks, it drips onto your feet. If its leaking from a line under car, most likely slave seal leak.

But check obvious, line connection fittings not tight.

 

I checked it, the line looks a little torn. Anyway to test a slave?
