Abstract:
A control system and method control release of a braking device from a wheel or disc. Release of the braking device is slowed or stopped based on a speed at which the braking device is released. The braking device may include a return limiting device through which a rod is configured to move. The return limiting device permits the rod to slide within the return limiting device while the brake pad holder releases from the wheel or disc no faster than a designated speed, but engages and restricts movement of the rod within the return limiting device while the brake pad holder releases from the wheel or disc faster than the designated speed.
