A brake system that includes a fixed brake system, a sliding brake system, and a support structure. The fixed brake system has an inboard side and an outboard side and being operable to move an inboard brake pad and/or an outboard brake pad against a brake rotor to generate a first clamping force. The sliding brake system being operable to move relative to the fixed brake system and to move the inboard brake pad and/or the outboard brake pad against the brake rotor to generate a second clamping force. The support structure providing a sliding contact between the sliding brake system and the fixed brake system during movement of the sliding brake system relative to the fixed brake while generating or releasing the second clamping force. The support structure is located in a region of the outboard side of the fixed brake system.
