Brake fluid leak

[gar123]

I backed up my car from the garage and low and behold, brake fluid on the floor. I checked the ABS reservor and filled it. I also filled the rest of the reservoirs. I've been monitoring the leak and reservoirs. i just don't understand why it leaked alot one night and very minimal since then. I've done the braking hard scenario because I can hear the ABS pump making that noise. When my car sits for more than a day, the ABS pump makes this sound and goes away after a few minutes. Any ideas on what to check next? Is the ABS pump going bad. I hear sometimes the pump gets dry and that's what causes the sound until it gets lubed up by brake fluid. Any suggestions are welcome.

This is all classic ABS behavior for the NSX (pre-2001 anyway). Please do a search on "ABS" and you will find more then you want to read about this topic.

It was probably a one time burp of the ABS system. Mine did that once and it's been fine since then.
The ABS pump on my 91 does not run each time it is started.
I think it only runs if the pressure has fallen from use or if the brake bomb is faulty. Careful messing around with it as the system is under thousands of pounds of pressure.
