FIELD: process engineering.
SUBSTANCE: set of inventions relates to machine building, particularly, to disc brake piston jackets. Claimed piston protection jacket is arranged between the caliper and piston. Said jacket has a bulged fillet made at its inner section to fit in the piston groove and an insert fitted in the jacket at its moulding. Said insert is secured in a circular recess made in the caliper. The jacket can be folded for said insert, mid sections and extreme section to overlap each other. The jacket has lengthwise ribs arranged at the inner section surface to support this section, that is, to facilitate the stiffness and to allow the air to leak outside from said bulged fillet fitted in the piston groove. Claimed brake comprises the piston with protective jacket.
EFFECT: better disc brake piston tightness.
