I'm a newbe with the 1990 Acura Legend. I have a leak in my ABS system that drains the reservoir overnight. Also the brakes work just fine. I have taken the plastic under cover off to look for the source but no luck. Also checked with the engine on and off with someone pumping the brakes, no luck. Has anyone had this problem. Thank you.

i have the same problem with my 88. I still haven't found an answer.
