Retrofit To Disk Brake Wheels

Many modern gliders and power gliders are originally equipped with disk brake wheels nowadays. To make available their advantages also for elder aircraft types, TOST offers 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.

Hydraulic Shoe Brake Wheel

To increase the braking force of the 4″and 5″ shoe brake wheels, they can be fitted with a hydraulic actuated anchor plate. The advantage is that the friction of the mechanic actuating cables is omitted due to the hydraulic actuation. Thus, the brake gains power and is better doable. The effort of the modification is very low: only the anchor plate has to be exchanged. All connecting dimensions of the wheel (installation width, position of the anchor bolt) remain unchanged. The hydraulic actuated anchor plates are supplied including master cylinder, hydraulic hose and detailed working instructions.
