Improvements to brake blocks

摘要

A bicycle brake block comprises a brake pad (1), a support body (2) and means (4) for visually indicating when the brake pad is worn down to a predetermined level (7), said indicating means (4) being visible on the support body (2) and being triggered from a first to a second state when the pad is worn to said level. The second state is more visible than the first state and provides a brake wear indicator which is not readily overlooked. <IMAGE>
