A safety brake system for a trailer comprises a brake unit to brake the trailer. An actuation unit comprises a mount secured to a front end of the trailer. A brake interface is operatively supported by the mount for displacement with respect to the trailer. The brake interface is displaceable toward a deactivation state in which the brake interface releases the brake unit from braking the trailer. A probe is operatively supported by the mount for displacement with respect to the trailer, the probe being displaceable between a hitching state in which the probe is adapted to contact the hitch of a vehicle, and a blocking state in which the probe blocks a hitch coupler of the trailer to prevent hitching of the trailer to a vehicle A biasing unit biases the probe against the hitch of the trailer in the hitching state and toward the blocking state. A mechanism operatively connects the brake interface to the probe, the mechanism retaining the brake interface in the deactivated state when the probe is in the hitching state, the mechanism releasing the brake interface from the deactivated state when the probe moves to the blocking state. A method for deactivating a safety brake is also provided. |
