1. A brake operating arrangement comprising:
a cam member operable on a brake mechanism for braking a wheel, the brake mechanism being movable between a braking position and a non-braking position, wherein the cam member is rotatable to move the brake mechanism to the braking position;
a drive member movable in drive and return directions; and a ratchet mechanism to rotate the cam member when the drive member is moved in the drive direction, the ratchet mechanism being connected to the drive member and the cam member;
wherein the cam member is rotatable between a force applying condition and a release condition, whereby when the cam member is in the force applying condition, the cam member applies a force to the brake mechanism to maintain the brake mechanism in the braking position;
wherein the cam member has a force applying region to apply said force, and the force applying region comprises a radially outwardly facing force applying surface.
