A lot of entry level and late 90's cars still use rear drum brakes. So when the ABS became standard equipment, a lot of these rudimentary units only have three valves - two for the front discs, and one for the two rear drums. The only thing that I can think of that you need to make it work would be wheel speed sensors. Usually either a hall effect type sensor or a reluctor. On the (handful of) mid 70's Cadillacs that were offered with antilock brakes, the differential had a reluctor fitted into it as a rear wheel speed sensor. I think this method is still used, in particular with trucks, since some still use drum brakes. I'm not familiar with the types of wheel speed sensors used out there, but I don't see how a retrofit can't be done. Like anything with our cars, it's a matter of time and $$$. Followed by the next crossroads of opinions about a car's value in original form versus modified or modernized. Chris Middlebrook 1962 Custom Southampton --- On Thu 10/12, Klebert L.
