A hydraulic brake controller does not only dispose a first oil-return hole, which is connected to an oil storing space, at a stroke place of allowing a piston to reciprocate in a main oil cylinder, but also disposes a regulating screw, which stretches the first oil-return hole, on a controller main body. The speed of returning hydraulic oil to the oil storing space can be controlled by simply changing the degree of the regulating screw stretching the oil-return hole so that time of allowing the piston passing through the oil-return hole to completely impose the braking force on the brake pad can be extended or reduced, thereby achieving a goal of conveniently regulating the braking sensitivity.

The hydraulic brake controller as recited in claim 1, wherein a spring is disposed between the piston and the main oil cylinder of the controller main body. 3. The hydraulic brake controller as recited in claim 1, wherein an axis of the regulating screw is leveled at an axis of the first oil-return hole, and a hand push portion, which is exposed to the controller main body, is disposed to an end of the regulating screw, and a spring is disposed between the piston and the main oil cylinder of the controller main body. 4. The hydraulic brake controller as recited in claim 1, wherein an axis of the regulating screw is vertical to an axis of the first oil-return hole, and a hand push portion, which is exposed to the controller main body, is disposed to an end of the regulating screw, and a spring is disposed between the piston and the main oil cylinder of the controller main body. 5. The hydraulic brake controller as recited in claim 1, wherein an axis of the regulating screw is vertical to an axis of the first oil-return hole, and the controller main body has at least one second oil-return hole connecting between the main oil cylinder and the oil storing space disposed to the screwing place of the regulating screw. 6. The hydraulic brake controller as recited in claim 1, wherein an axis of the regulating screw is vertical to an axis of the first oil-return hole, and a hand push portion, which is exposed to the controller main body, is disposed to an end of the regulating screw, and the controller main body has at least one second oil-return hole connecting between the main oil cylinder and the oil storing space disposed to the screwing place of the regulating screw, and an angle is regulated at an axial place of the screw, and oil return is controlled upon a size of a cross-sectional area. 7. The hydraulic brake controller as recited in claim 1, further comprising an inner bump disposed to a tail of the bushing, and a circular groove for wedging the inner bump circularly disposed to the sleeve. 8. The hydraulic brake controller as recited in claim 1, further comprising a stage formed between the main oil cylinder and the oil storing space of the controller main body and serving to hold the sleeve and the bushing.
