A drive device for a braking system of a motor vehicle. The drive device includes a housing and an electric machine that includes a rotatably supported drive shaft. The drive shaft is connected or connectable to an actuator element of the braking system via a planet wheel gear situated in the housing. The drive shaft is rotatably supported in a bearing shield situated in the housing. The bearing shield is made of plastic.

A system comprises a slave cylinder for a motorcycle. The slave cylinder may include a rod with a height which is hydraulically adjustable by a hydraulic pressure adjuster. A motorcycle slave cylinder is also provided which includes a rod having a height. The motorcycle slave cylinder also includes a hydraulic pressure adjuster. The hydraulic pressure adjuster hydraulically adjusts the height of the rod above the motorcycle slave cylinder.

The present invention provides a safety training device capable of being attached to an existing front-wheeled walker. The safety training device a modified ski unit, a braking mechanism, a brake cable and hose. When improper transfer techniques are utilized by a patient, the modified ski unit engages the brake and cable hose to exert a force to the braking mechanism. The braking mechanism activates a braking member on the wheel of the walker, halting further movement of the patient and walker. Simultaneously, a striking member of the braking mechanism makes contact with the frame of the walker, producing an audible cue, alerting the patient and any healthcare professionals present that improper technique is being used in a transfer.

A brake cylinder with a cylinder body having a first flange extending radially therefrom to form a radial edge with a bevel and a non-pressure head having a second flange extending radially therefrom, wherein the second flange is spaced apart from the first flange to define a first gap and includes an angled portion that extends over the bevel of the first flange to define a second gap in communication with the first gap. The two flanges form a gap in communication with the interior of the brake cylinder that extends outwardly to a V-shaped gap between the bevel of the first flange and the angled portion of the second flange to define a brake cylinder vent. The vent may be limited to four predetermined locations spaced equidistantly about the brake cylinder or the vent may extend circumferentially about the brake cylinder.
