After the brake pad 17 is worn, the measuring rod 43 is close to the brake disc 2, so that the measuring rod 43 is driven by the outward movement driving force, the position of the outer end of the measuring rod 43 in the compensation cylinder 42 is changed, the pressure of hydraulic oil in the compensation cylinder 42 is increased, the adjusting sleeve 41 is further driven to move inward, the brake piston 12 is driven to move towards the brake disc 2 under the action of the pretightening force of the return spring 13 between the adjusting sleeve 41 and the brake piston 12, and the cross sectional area of the measuring rod 43 accounts for half of the cross sectional area of the compensation cylinder 42, so that the outward movement distance of the measuring rod 43 is equal to the inward movement distance of the brake piston 12, and the wear thickness of the brake pad 17 is compensated, namely, the brake clearance between the brake pad 17 and the brake disc 2 is compensated.
The non-return structure limits the outward movement of the adjusting sleeve 41 and prevents the rebound of the compensation gap.
