I was only kidding! (man, you must think I'm a goof!)
The brake fluid is black. In previous cars, when the fluid has turned black and the pedal has gotten hard, a good flush brought them right back. I generally drive Toyotas, and in my '85 Corolla GTS, my '88 Supra, and my Mom's '86 Camry, this has brought the pedal feel back to where it should have been.
I'll be doing the brakes in a few weeks, all the way around, most likely with new cylinders in the rear if necessary. i don't know the condition right now; I haven't had the thing apart since I bought it, but they are overdue and the last owner wasn't known for maintenance. I am assuming the cylinders are tight, but they are not leaking.
Figure while I have it apart...
I don't know if you remember, but I am the guy that installed the loud stereo so I don't have to listen to the engine ticking like a time bomb...
