Abstract
A fluidically actuatable disk brake system includes brake cylinder pairs each including brake cylinders arranged on both sides of a brake disk in at least one brake caliper. Each brake cylinder includes a brake piston and a spring arrangement which applies a spring force toward the brake disk. First and second fluid connections are provided on the brake cylinder. The first and second fluid connections supply a fluid to the brake cylinder so that a force counteracting the spring force is applied to the brake piston. A 2/2-way valve is assigned either to the first or second fluid connection of first brake cylinders of a brake cylinder pair. The first or second fluid connection which is not assigned to the 2/2-way valve is fluidically connected to the respective other first or second fluid connection of a second brake cylinder of the brake cylinder pair.
