    The ABS light comes on and the abs kick in even when I don't need it making it hard to stop quickly at low speeds.

    ABS and Brake light come on at intermittent times after I start driving my 2001, 2WD S10. Dealer charged me $50 to check and said a relay in the ABS system was bad. They wanted $1300 to fix it. This problem started around 2004. About six months ago I came across this problem on something I read, and found out it is a COMMON problem with this brake system. Still no recalls. Worst, if you pay the $1300 for the same relay, how long is it going to last?

    The ABS system engages at low speed when normal brake pressure is applied. The brakes are then rendered useless.

    ABS system started to come on when easily braking. Then, it finally stopped and the ABS light came on. ABS system no longer works.

    Turned out that the problem was a shorting ABS sensor in the right front wheel hub. Designed so that you cannot replace just the sensor. I had to replace the entire wheel hub. Problem is fixable, but you should redo the brakes at the same time.
