1996 SS Impala ABS problem

Hello to all.

I have a good friend that is having troubles with his ABS. When he hits a "bump" or pothole, the ABS pulsates his brakes and he is having a difficult time stopping when this occurs. He already has had a minor accident due to hitting a pothole and slid into the back of someone that "stopped short". Any remedies known of for this problem?
Any suggestions are welcomed.
Thank you in advance

Nova's flyin, get some wheelie bars, hold "er" down for another .1 et! The abs isssue, get it on an abs capapble scanner, find the bumpy roads and watch the 4 wheel speed sensor inputs to the abs as shown on the scanner, you will probably see one speed sensor drop out causing the abs to actuate as the system assumes one wheel is locked.

Thanks for the reply. Will do!
As for wheelie bars, not allowed in the class. Wild Street is limited to 10 inch tires and no whellie bars. Go as big as you want on power. No computer traction devices no nitrous controllers either.

Have a blessed day
