The working principle is that when the brake is needed, the brake is stepped down to drive the hydraulic driving block 11 to slide towards the inside of the driving groove 103 through the internal transmission system, at the moment, the hydraulic pressure inside the driving groove 103 is driven to enter the two hydraulic grooves 102 and act on the weak magnets 7, then the weak magnets 7 are pushed to move outwards and drive the friction blocks 3 to move outwards together until the friction blocks contact with the surface of the brake disc 2, the sliding limiting blocks 12 can also be driven to slide together in the process that the weak magnets 7 slide outwards, the sliding of the sliding limiting blocks 12 can extrude the hydraulic pressure inside the U-shaped groove 106 to drive the piston sliding blocks 13 to slide and compress the metal corrugated pipes 14 to the minimum length, at the moment, the friction blocks 3 contact with the brake disc 2 and generate pressure to carry out friction braking, and wind current is generated at the wind guide groove 201 in the rotating process of the brake disc 2, and blows the rotating wheel 4 at the top along the outer ring of the brake disc 2 and drives the brake disc to rotate, when the rotating wheel 4 rotates, the internal lead 5 can be driven to rotate together with the rotating wheel and continuously cut the magnetic induction line of the strong magnet 18 so as to generate current, the current is rectified and adjusted by the current converter 8 and then acts on a circuit, then according to the principle of electromagnetic refrigeration, heat generated by the friction block 3 due to braking is absorbed by the electromagnetic heat absorption block 6, and then the heat is transferred to the electromagnetic heat release block 9 through the heat exchange medium 10 arranged in the brake caliper 1, so that the friction block 3 can realize the cooling effect, thereby ensuring that the internal hydraulic pressure is not influenced by high temperature, and reducing the probability of air resistance generation;

when the brake is deeply stepped on for a long time, part of the surface of the friction block 3 is abraded and the whole friction block 3 moves towards the surface of the brake disc 2, at the moment, the weak magnet 7 continues to move by a small displacement amount, at the moment, the movement of the sliding limiting block 12 enables hydraulic pressure to enter the hydraulic pressure adjusting cavity 107 only through the first one-way valve 15, then, when the brake is released, the friction block 3 contracts towards the inside of the hydraulic pressure groove 102 under the action of reset hydraulic pressure and the weak magnet 7 drives the sliding limiting block 12 to slide, at the moment, the sliding limiting block 12 slides and drives the hydraulic pressure in the U-shaped groove 106 to flow downwards and further drive the piston slider 13 to slide, as the U-shaped groove 106 is in a U shape, the piston slider 13 directly abuts against the side wall, at the moment, the sliding limiting block 12 limits the weak magnet 7 without sliding any more, namely, the friction block 3, and ensures that the backing-back displacement amount is a fixed value, at this time, the hydraulic drive block 11 continues to retract under the action of the return spring 16 and the return hydraulic pressure, and at this time, the hydraulic pressure in the hydraulic adjustment chamber 107 is partially supplemented to the hydraulic groove 102 and the drive groove 103 by the hydraulic pressure difference on both sides of the second check valve 17, so that the hydraulic drive block 11 can accurately retract to the original position to complete the whole braking and adjusting process.
