  • Mechanical pad wear indicator
    Patent number: 10436271
    Abstract: An apparatus for indicating air disc brake pad wear includes a housing having a proximate end and a distal end; wherein a first opening is located at the proximate end. The housing receives a first rigid member having a proximate end and a distal end and partially contained in the housing, the first rigid member distal end extending from the distal end of the housing and configured to attach to an associated inboard disk brake pad assembly. The first rigid member moves linearly in response to the movement of the associated disc brake pad such that the proximate end of the first rigid member as seen through the first opening recedes as the associated disc brake pad wears. The housing may also receive a second rigid member configured to attach to a carrier of the air disc brake assembly for determining wear on an outboard disc brake pad.
