My 2006 HHR doesn't have ABS.
How often has ABS actually engaged in your past cars?
If practicing good hypermiling techniques, you will already keeping more buffer space, downshifting while stopping, and paying more attention to the road.
Try 'threshold braking' for searches.
Some quick links:

http://en.wikipedia.org/wiki/Cadence_braking
Not the best on how, but a start.
Threshold is hard braking approaching wheel lock up. I try to practice it on dry roads, because I figure it results in less brake wear than the long brake method everyone seems to use.
Cadence is the technical term for pumping brakes in times of poor traction.
