The RCR brakes are designed with two clear goals in mind, namely efficiency and durability! 

The construction is not arbitrary, both design and materials used are the result of a
cooperation between RCR and the best expertise in the areas.
Many prototypes of various and varying materials are tested over time, until we reached the final design.

The materials meet the requirements based on military specifications and
are traceable back to melting furnaces!

These brakes work extremely well; you will probably sell your Baja before these brakes wear out!
