Wheels lock up
According to my idiot lights I have ABS as a light appears whenever I start the truck. However, the light goes out like normal and off I go. It's been raining a lot here lately, my tires aren't that great and I have had to make more than a few quick stops. To my surprise, my wheels lock up and I slide to a stop. At first I thought maybe I didn't slide far enough to for the ABS to engage (although I had thought it would be mostly instantaneous), so I went off to a wet, empty parking lot to test my brakes. Well the wheels lock up and stay locked until I finally stop. No pulsing of the brakes you normally feel in the pedal or anything like that. I have no lights on the dash at all. It would appear, at least as far as my dash indicators go, that everything is working just fine with my truck, but that isn't the case. Any ideas?
2000 SuperCab 3.0 FFV. No real mods, just a stock truck mostly. I don't really intend on doing any mods just a do-it-yourselfer...
