[0025] A telescopic seal is provided on the outer side of the movable column 2, which is fixed in the slide groove 1-2 and abuts against the movable column 2. The telescopic seal is used to seal the gap between the movable column 2 and the slide groove 1-2, thereby preventing dust from entering the gap between the movable column 2 and the bracket body 1, thereby improving the service life of the movable column 2 and further improving the service life of the brake bracket.

[0026] As a preferred solution of the utility model, a piston rod 4 is installed on the piston 3, and the piston 3 is arranged in the middle of the piston rod 4, and both sides of the piston rod 4 extend out of the piston cavity 1-1 respectively. One end of the piston rod 4 is connected to the movable column 2, and the other end is provided with a brake pad detection component, which is used to detect the thickness of the brake pad.

[0027] The brake pad detection assembly includes a mounting plate 5 and a distance sensor 6. The distance sensor 6 is mounted on the piston rod 4 through the mounting plate 5. The distance sensor 6 is adapted to the end face of the bracket body 1, that is, the distance sensor 6 is arranged toward the end face of the bracket body 1, and is used to detect the distance between the distance sensor 6 and the end face of the bracket body 1.

[0028] In this embodiment, a clamping cavity 1-3 is provided in the bracket body 1, and a brake pad 1-4 and a brake disc 1-5 are provided in the clamping cavity 1-3. The brake pad 1-4 is arranged on both sides of the brake disc 1-5.

[0029] The brake pad thickness detection method is as follows:

[0030] (1) When the brake pad is new, place the brake pad against the brake disc. At this time, the distance between the distance sensor 6 and the end surface of the bracket body 1 is X;

[0031] (2) driving the movable column 2 to extend out of the slide groove 1 - 2 , so that the brake pad abuts against the brake disc, and detecting the distance X1 between the distance sensor 6 and the end surface of the bracket body 1 through the distance sensor 6;
