Brake fluid leaking from the right side under the door?
 

My 99 7.3 recently started leaking brake fluid? It seems to be coming down from the cab or somthn? Iv noticed it on my floor mat also.. Please help! It looks like it's getting worse and I'm thinking it's the master cylinder maybe?? I havnt lost any pressure. But it's very weird when I park it and there's brake fluid right under the drivers side door?

is your truck a 6 speed? could be your clutch master too. have you turned upside down in the drivers seat yet? haha
