89 tr: Fluid leaking onto brake pedal and floor mat area

I have an 89 testarossa which I drive pretty regulary. In the summer I think one of my fans stopped working and I overheated while ideling on driveway waiting for my lift to drop. It was very hot that day. I'm due for a full service so I put it away. I had taken it out once or twice since just to run it for a while on a cooler day. The last time I had it out was in October.
I took it out yesterday and noticed my feet were slipping a bit on the floor under the pedals. I noticed some fluid down there and on the surface of the brake pedal.
My brakes worked well and I shortened my trip quite a bit and basically just headed back to the house and put it away.
I'm far from a mechanic and I just wanted to know exactly where you think its coming from. I assume somehow the brake booster is leaking back into there and down onto the floor.

Thanks in advance!

 

I have never seen fluid anywhere before except for the occasional oil dripping on the floor. I haven’t checked the brake fluid and like I said the brakes work great and so does the clutch. This seems to be a new problem so I’m not gonna mess with the car. Typically I take it out once a week or at least once every two weeks for 30-40 miles.
I think it’s staying in the garage untill it goes in for the service currently scheduled for March at J scuderia.


I have a 911 that was loosing brake fluid and I had to replace the fluid 3 times and never saw a drop anywhere. It was the clutch slave leaking inside. Which apparently uses brake fluid.
I’m not sure if a testarossa has that type of setup.

 

Thank you. I will check ASAP

 

Thanks again!
