Hydraulic brake control apparatus

A hydraulic brake control apparatus including a body portion (110), a hydraulic brake control mechanism, and a lever portion (160). The body portion (110) has a first section (130) configured to fit within an interior of a bar opening and a second section (112) configured to be mounted outside of the interior of the bar opening. The hydraulic brake control mechanism includes a hydraulic brake pressure cylinder (131) having a piston chamber (200) therein, where at least a portion of the hydraulic brake control mechanism is housed within the first section (130) of the body portion (110). The lever portion (160) connected to the body portion (110) and configured to actuate the hydraulic brake control mechanism. The body portion (110) includes a port (202) fluidly connected to the piston chamber (200) by a conduit (204). The port (202) is provided on the second section (112) in order to allow bleeding of air from within the piston chamber (200) when the body portion (110) is mounted to the bar opening.
