A control system for a parking brake mechanism for a foundation brake, the parking brake mechanism incorporating an electric actuator, an extensible device drivably connected to the actuator and a resilient device arranged to act on the extensible device and maintain a desired level of force to be applied by the parking brake mechanism in the event of contraction of components of an associated foundation brake, the control system being configured to signal the following sequence of operations to apply the brake: a) application of an associated service brake actuator to apply the brake; b) driving of an electric actuator to bring the extensible device up to a point at which it retains the parking brake in the braked position achieved by the service brake actuator; c) the release of the service brake actuator; d) the driving of the electric actuator to compress the resilient device; e) monitoring a characteristic of the brake to determine if a desired force has been applied by the parking brake; and f) driving of the electric actuator to stop once a desired force has been reached.
