  "textContent": "An overrunning disk brake, according to the invention having a body and brake blocks pressed against a brake disk by means of a pressure unit placed slidably in a chamber joined hydraulicly with a brake assembly, characterised in that, a brake block ( 2) situated from the inner side of the brake disk ( 4 ) is provided with a pin ( 5 ) protruding above a surface of the brake block ( 2 ), and at one side of the pin ( 5 ) there is a spring ( 7 ) placed basically parallel to a surface of the brake block ( 2 ), whereas the pressure unit ( 8 ) is made of an inner piston ( 10) placed slidably in an outer piston ( 11 ), and the inner piston ( 10 ) comprises a pin ( 12 ) on which there is a return spring ( 14 ). In the outer piston ( 11 ) there is a recess ( 15 ) situated from side of the brake block ( 2 ). Advantageously frontal surface ( 6 ) of the pin (5) of the brake block ( 2 ) and frontal surface ( 13 ) of the pin ( 12 ) of the inner piston ( 10 ) are sloping, moreover slope of the frontal surface ( 6 ) of the pin ( 5 ) of the brake block ( 2 ) complies with slope of the frontal surface ( 13 ) of the pin ( 12 ) of the inner piston ( 10 ). Pistons ( 10 ), 11 )) are situated in the pressure unit ( 8 ) in such a way that during braking, the outer piston ( 11 ) and inner piston ( 10 ) move together, however, when wheels of a trailer rotate towards opposite direction than during driving forwards, the inner piston ( 10 ) advances the outer piston ( 11 ) with such a quantity, so that capcity of the chamber ( 9 ) under two pistons be larger than delivery of a brake pump.",
