[V8] ABS thing

[Ed Kellock]

The ABS defeat button doesn't do anything with power assist. It merely
senses and defeats lockup in extreme braking. 

Did he use the right fluid? Which reservoir did he "top off"?

What were the test conditions between feeling fine and feeling weird again? 

I know it's tough to do long-distance troubleshooting... gotta ask a lotta
seemingly off-the-wall questions to define stuff.

Hey, got a call tonight from friend's son that's driving the '90  
Black car that I sold him.  Brake fluid was a bit low(min mark) and  
he refilled it then said the pedal felt wierd while driving.  I told  
him to push the "Antilock" button on the dash, and then it felt  
fine.  Turned it back on, and felt wierd again(pulsing/spongy)  To be  
honest, I've only pushed that button a few times when I first got the  
Lago car, and forgot it was even there till today.  Anyway, he said  
brakes felt awsome afterward, and I said "go with it".  Having never  
had to mess with any real ABS issues, not totally sure exactly what  
the button does, but am guessing it turns off that ABS booster/pump  
thing.  Just checking if anyone's got any ideas.....The car is a  
ferry ride/4 hrs of driving so I'm not gonna see the car till I go  
out there in May, so trying to do some long distance diagnosis with a  
younger guy who's not super mechanical, but trying.  He's gonna get  
it up and see if he can see any leaks from the brake system, but said  
after pushing the antilock button that it felt good.  Thanks, Tom
