A filter device for straining brake fluid in a hydraulic brake system comprises a disk shaped core the opposite sides of which are attached to a cup shaped bowl. A filter element is secured to one side of the core in one bowl. Nipples integral with the core extend radially outward and communicate with radial bores in the core. The bores have axial portions opening at opposite sides of the core in the bowls. One pipe may connect the filter device to the reservoir of a master brake cylinder via one nipple, and another pipe may connect the filter device to a source of brake fluid via the other nipples. A bleed hole adapted to be closed by a removable screw is provided in the outer wall of each of the bowls. The filter element may have a porous body made of sintered metal and may have a cylindrical outer wall with a reetrant conical wall.
