Abstract
A brake drum configured for providing an visual indication of braking surface diameter safe operating limits while the brake drum is mounted on a vehicle that includes one or more axially-oriented indentations defined in the braking surface, each of which is defined to a depth that is less than or corresponds to the maximum safe operating diameter of the braking surface.
Claims5
A brake drum comprising:
- a cylindrical drum body having an open end and a hub mounting plate;
- a cylindrical braking surface within said drum body;
- and
- an indentation defined in said braking surface, extending toward said hub mounting plate from said open end and having a depth such that when said braking surface is worn away through use said indentation is less perceivable;
- and
- wherein said depth at least corresponds to a pre-defined braking surface diameter.
3 more elements
A vehicle comprising:
- a brake drum defining an interior cylindrical braking surface and configured for providing an visual indication of braking surface diameter safe operating limits while installed on said vehicle, said brake drum including one or more axially-oriented indentations defined in said braking surface, each said one or more indentations extending from an inboard end of said braking surface toward an outboard end and having a depth at least corresponding to a prescribed safe operating diameter of said braking surface.
