A hydraulic vehicle brake includes a housing and first and second brake pistons at least partially located within the housing. The brake pistons are configured to cooperatively press a common friction pad against a rotor of the vehicle brake. Each of the pistons is a hollow piston including a substantially solid piston bottom. A clamp beam laterally spans the piston bottoms of the first and second pistons within the housing. The clamp beam is configured to selectively apply longitudinally directed clamping force upon the pistons. A spindle is selectively driven for rotational motion by an electric motor. The spindle is interposed laterally between the first and second brake pistons within the housing. The spindle is configured to reciprocate the clamp beam longitudinally within the housing responsive to a direction of the rotational motion.
