Retrofit of complete hydraulic brake system

The retrofit of the hydraulic brake system in Schempp-Hirth gliders results in a clear increase as well as a better modulation of the brake force. Pilot and copilot can equally brake at the same time. All control sticks are equipped with a master cylinder. The control stick is replaced by a CNC-milled version; in double seaters this applies only to the forward control stick. The complex brake actuation via a bowden cable is no longer necesssary and a significant improvement in the braking force and the operational safety can be obtained.

An existing disk brake wheel can still be used further on. The retrofit can be carried out easily and quickly in a gliding club’s workshop.
