Brake assembly BZT and BZTM

The 3-piston brake assembly BZT is designed as a floating brake caliper and can be mounted to 3.5′′, 4′′ and 5′′ disk brake wheels of the series Max II, Tria and Penta. The brake assembly features an extremly light weight of 440 g and very compact outer dimensions. Because of the metric screw connection the change of the brake linings can be carried out without any special tools.
Especially for light, single-seated sailplanes or UL-motorplanes, in which a low weight of the components is important, the brake assembly BZT is convenient.
