Air Canada's B-727s had nosewheel brakes but eventually they were de-activated, (removed?).
The N/W brakes did not actually come into operation and apply any braking unless the pedals were flat to the floor, or close to it, I can't remember the exact threshold where they came on.
In everyday service full braking very rarely happened and the N/W brakes were never really required for performance purposes, so they were seen as a weight and maintenance cost that was not justified.
