 Parmac’s new generation of Hydromatic® Brakes are more efficient for their size and weight. These include the following models: 121, 122, 201, 202, SSR28, 262, 341, 342, 451 and 481. These newer brakes have an improved sealing arrangement for better sealing and longer seal life, which also simplifies their replacement. Some of these new models offer easier controllability, and will fit in the old cradle without modification.

 SEAWATER MODELS–Standard brakes require fresh water, free of all foreign substance. When seawater is the most economical and readily available water source, certain models of Seawater Hydromatic® brakes can be made available.

 HELICOPTER TRANSPORTABLE–Brake models 341A, 342A, and 451 are special brakes with aluminum components, and weigh less than 4,000 lbs. The 481 and V200 brake models can be furnished with some aluminum parts to reduce weight.
