You don't state mileage on the car but I'm betting well over 100K. The master cylinder is sold as a one piece kit which has the line and the slave cylinder attached to it. More than likely your slave cylinder has gone bad, which means you'll have to drop the transmission to get it out as it's an internal mechanism that pushes your throw out bearing to engage your clutch. Yes it's time to also change the clutch and pressure plate too, you may as well as long as you have to drop the transmission AND in order to do that my friend, you're going to have fun, because the whole front of the car has to be lifted and the WHOLE X sub-frame has to be dropped which means struts and all have to be disconnected.

pull on the emergency brake do the DRL go out?

Hi Tim Short answer is, yes, a cracked seal, or worn out gasket could be at the root of the leak. That said, the transmission is a major component of your drivetrain.
