Claim:
1. A brake mechanism for halting a rotating assembly, the brake mechanism comprising; a first braking surface; a second braking surface; and a trigger that releases the second braking surface to engage the first braking surface when the rotating assembly attains a desired rotational speed, wherein the second braking surface comprises at least one shoe assembly, wherein the shoe assembly is pivotably coupled to the rotating assembly about a shoe assembly pivot point, and where the trigger permits passage of the brake shoe assembly from a first, cocked position to a second, engaged position responsive to centrifugal force resulting from the rotational speed such that at least a portion of the second braking surface of the shoe assembly rotates beyond the shoe assembly pivot point into engagement with the first braking surface wherein the shoe comprises a pair of compliant flexures disposed about the shoe assembly pivot point such that the brake mechanism is configured to yield plastically upon engagement with the first braking surface.
