These are basic rubber ring brakes for your sport jet applications.  The drum/wheel assembly is light weight aluminum, and is designed to use inexpensive DuBro 3", Low Bounce tires. (lite tires can be used too)  The DuBro tires are inexpensive to replace, and are available at your local hobby shop.

The brake hub uses a sealed ball bearing to keep things aligned, and they operate very well, down to 40 psi.  They are also available in 2 styles.  The fist style is the "Shock Jet" style, and fits a 3/16" Dubro axle that can be bolted to bent aluminum landing gear.  The second style is designed to be used with a 3/16" wire landing gear leg.  There is plenty of meat in the hub, and drum to drill to 1/4", or up to 8mm.

The basic brakes do not come with tires or axles.  In the future, I will be making them available.

NOTE:   There may be a patent issue with these brakes, so the cart button is disabled until I can resolve it.
