Checking brake disc minimum Notes

Micrometer Check Brake Disc

Along the innermost and outermost friction disc tracks that have no holes, wear of the corresponding brake pad friction area is lowest - compared to the center hole area -if the brakes are subjected to high contact pressures. As a result, less severe braking will lead to a corresponding increase of surface pressure in these areas and, hence, to increased friction disc wear. The natural ratio of heavy to light braking will produce the typical wear profile of a perforated friction disc in...
