Abstract

A braking system for safely collecting brake dust produced by operation of a braking mechanism. The braking system comprises a collector apparatus coupled with a braking mechanism. The collector apparatus is able to include a shroud that surrounds the braking mechanism and a catch element coupled with the shroud for collecting brake dust exiting the shroud. As a result, when coupled with the braking mechanism, the collector apparatus is able to ensure that most or all brake dust, such as copper or other particles from the braking mechanism that break off from the breaking mechanism during operation of the braking mechanism, are removed from the braking mechanism and collected by the filter/catch of the collector mechanism.
