Abstract:
1. A brake caliper for disc brakes, comprising: a main rigid body, which can be coupled with a portion of a structure or a vehicle in proximity of a braking disc, said main body defining at least one seat; at least one piston slidingly housed in said at least one seat and movable between an operative position to exert, by a layer of friction material, a thrust on the braking disc, and an inoperative position in which said piston is detached from said disc; a fluid-sealing means fixed on each piston and acting between the piston and the respective seat; an elastic means fixed on each piston and acting between the piston and the respective seat to exert at least an action of elastic return onto the piston during the sliding thereof, wherein each piston defines, in cooperation with the respective seat wherein said piston is inserted and with the sealing means, a first chamber in fluid communication with actuation means, each piston comprising a side surface which delimits, in cooperation with a side surface of the respective seat, with the sealing means and with the elastic means, a second chamber: and a tapping means to provide a fluid communication between the first chamber and the second chamber.
