FIELD: automotive industry; brake with boosters.
SUBSTANCE: proposed brake has brake master cylinder, main piston, control rod coupled with brake pedal, brake booster coupled with control rod, and emergency brake valve with piston conveying reactive force inside which amplification factor regulator with head is arranged, being located in space between piston conveying reactive force and bushing installed in front part of central hole of main piston and provided with central hole. Quick-acting piston is arranged in central hole. Rear end of said piston forms, together with head of amplification factor regulator, shutoff valve which closes central hole of quick-acting piston at inlet. Brake contains device formed by slide fitting of bushing in hole of main piston and designed for limiting pressure differential between pressure in space and pressure in part of hole of main piston arranged before bushing in which bushing in fitted-in, pressure of which being lower than pressure at which shutoff can open.
EFFECT: reduced noise at braking.
