Dust covers 6 are installed at both ends of the cylinder block 1, and a piston 3 is installed in the middle of the dust cover 6;

[0028] A connecting hole 103 is opened on the upper surface of the cylinder block 1;

[0029] The filter assembly 2 includes a filter cylinder 201. The filter cylinder 201 is a single-side closed cylinder. A cover body 202 is installed on the upper surface of the filter cylinder 201. An outlet oil pipe 203 is provided on the lower surface of the filter cylinder 201. The outlet oil pipe 203 is installed inside the inlet oil pipe 101. A filter screen 204 is arranged inside the outlet oil pipe 203. A connecting pipe 205 is provided on the outer surface of the filter cylinder 201;

[0030] A connecting block 207 is provided on the outer surface of the filter screen 204, and a placement groove is opened at the inner bottom of the filter cylinder 201, and the connecting block 207 is installed inside the placement groove;

[0031] Through the coordinated use of the filter cylinder 201, the cover body 202, the outlet oil pipe 203, the filter screen 204 and the connecting pipe 205, the brake fluid entering the cylinder block 1 can be filtered, avoiding the dissolution of impurities in the brake fluid inside the cylinder block 1 after long-term use, resulting in the turbidity of the brake fluid and the reduction of the boiling point of the brake fluid, affecting the use of the brake caliper, and achieving the effect of extending the service life of the brake caliper;
