Brake booster for motor vehicle, has body with plunger piston integrated to control rod actuated by brake pedal, and magnetic washer attracted toward piston by magnetic attraction forces between washer and piston
Brake booster for motor vehicle, has body with plunger piston integrated to control rod actuated by brake pedal, and magnetic washer attracted toward piston by magnetic attraction forces between washer and piston
The booster has a control body (20) integrated to a control element that provides control force of brakes. The body comprises a plunger piston (44) that is made of a magnetic material and integrated to a control rod (48) which is actuated by a brake pedal. The body has a magnetic washer (94) that is collinear to the rod. The washer is attracted toward the piston by magnetic attraction forces between the washer and the piston. The washer, piston and the body cooperate, when the pedal is in rest, for obtaining contact between the washer and a face (100) of the piston.
