The master cylinder is operated by the brake pedal via a linkage adjustable in length. It has the following task: pressure generation in each brake circuit, compensation option for the brake fluid when temperature changes and rapid pressure reduction for quick release of the brakes. The tandem master cylinder consists of two main cylinders connected in succession. In a common housing there are the pressure rod piston and the floating intermediate piston. Both pistons are designed as double pistons, i.e. between the front and rear sealing piston part lies the annular trailing chamber. This is always filled with brake fluid via the trailing bore. The primary sleeve sits at the front of each piston. It seals its pressure chamber when the brake is actuated after passing over the compensation bore. The filling disc prevents it from pressing into the filling holes and thus their destruction. Secondary and vacuum sleeve seal the rear pressure rod piston towards the vacuum brake booster. The intermediate piston is sealed to the rear by two separating cuffs against the pressure rod circle.
