Antilock Brakes
87 951. The antilock lights up when turning on the ignition and on start-up it lights then goes out. In 4 yrs. of some very hard braking I've never had the light come on or feel the classic pulse in the pedal. Oddly the only time the dash light came on was when the car was running on stands while trying to duplicate clunking coming from the rear. Was not able to duplicate clunking BTW and have not heard/felt it since, but First time I touched the brake pedal antilock dash light came on and stayed on until I turned the engine off. On restart lights as usual then light goes out as usual. While continuing trying to duplicate clunking while running on stands applied brakes multiple times antilock dash light did not come on. Other than this one instance has the dash light come on in the last 4yrs. Is it possible my ABS is not working? Is there a way to test?

Sounds like normal behavior (except for when on the stands and the light came on). Do you get the fart sound from the ABS pump when you start driving?
Find a cold morning and when the tires are still cold, get up to ~40 mph, then stomp on your brakes until you come to a full stop. The fronts should lock up and you'll feel the pedal pulsate. It's pretty evident in these older systems. Alternatively, as suggested, a gravel or dirt lot works as well.

I find it very difficult to force the ABS to engage unless it's pretty slippery outside. Even with cold summer tires in the winter, I can't get it to kick in if the road is dry, and I know because I've been trying a lot lately, in order to troubleshoot something.
