Abstract
A bleeder arrangement for a hydraulic system of the type used in vehicle brakes. It includes a bleeder screw and bleeder passage construction which completely protects the bleeder screw threads from any exterior corrosive agents. The screw body is arranged to radially clear the housing in which it is installed so that corrosive action will not tend to seize the screw body to the housing. A seal arrangement also protects the valve portion of the bleeder screw from corrosive action as well as preventing fluid spillage during the bleeding operation.
