Any reason not to use ABS?

[mr henderson]

One of the hassles in building a kit car is to get the brake balance right. This means using a balance bar and twin master cylinders, or using a conventional tandem cylinder and finding a way of ensuring the rears don't get enough pressure to lock first under any circunmstances.

And that's the problem- ensuring the rears never lock first usually means that on some surfaces they won't be doing much at all, in other words, adjusting for every situation means compromising some of them.

Seems to me that if I was to use the ABS system from any car that would provide a suitable unit, and find a way of mounting the associated individual speed sensing equipment to each wheel, then I would get perfect braking every time.

Anyone want to shoot that idea down?
