TOST Retrofit From Shoe Brake to Disk Brake Wheel
Many modern gliders and power gliders are originally equipped with disk brake wheels nowadays. To make available their advantages also for elder aircraft types, we offer retrofit kits from shoe brake wheel to disk brake wheel.
Depending on the aircraft type the available space varies. With very tight space in the landing gear box the existing shoe brake wheel has to be replaced by a complete new disk brake wheel. If there is more space available, a brake disk only can be fitted to the existing wheel hub, after removing the shoe brake assembly.
Approved retrofit kits, where the existing shoe brake wheel is replaced by a new disk brake wheel or a brake disk is fitted onto the existing shoe brake wheel.

Please allow approximately 4 weeks delivery time for your TOST Retrofit Kit.
Required work: Installation of the wheel unit, brake assembly and master cylinder with reservoir, laying of hydraulic hoses, filling and bleeding of the system. We may recommend you to contact the responsible inspector before you start the process of modification. Thus you can coordinate the procedure of a “single piece” approval through the EASA if required. If you have only little experience with hydraulic systems, we would recommend to contact an appropriate work shop to have done that modification.
