Hey guys, I'm officially a newbeee, but I've been around for a while. I've been away from the boards for quite some time, and some might remember me as "Chubs".

Here's the question:
I jumped into my Challenger the other day to take it out on its monthly maintenance drive and the brake pedal pushed striaght to the floor. Pumping it does nothing.

Fluid is full and there are no obvious leaks (no puddles by any of the wheels, etc.).

Based on this, I'm betting master cylinder, but I can't remember the best way to test it. Can I get some ideas?

Thanks!

I'll go update my profile now...
