A supplemental control for a walk along materials handling vehicle including load carrying forks, a steerable wheel, a steerable wheel brake coupled to said wheel, a steering arm coupled to said wheel for steering said wheel and also being movable through an arc including a driving arc interposed between a substantially vertical braking position and a substantially horizontal braking position, a handle on said steering arm for control of said vehicle, a deadman mechanism for said steerable wheel brake to move said steering arm into said vertical braking position to brake said vehicle when said handle is released and a coast mechanism for selectively disabling said deadman mechanism, said supplemental control comprising:
- at least one supplemental controller mounted on said vehicle adjacent a base end of said load carrying forks, said at least one supplemental controller being actuated to move said vehicle when said coast mechanism is activated;
- and
- at least one coast release switch mounted on said vehicle adjacent a base end of said load carrying forks, said coast release switch being actuated to release said coast mechanism to apply said steerable wheel brake.
