A drum brake shoe has first and second webs, with the first web including a first end section to be located adjacent a brake shoe actuation element, a second end section to be located adjacent a brake shoe anchor element, and a central section extending between the first and second end sections. Similarly, the second web includes a first end section to be located adjacent the brake shoe actuation element, a second end section to be located adjacent the brake shoe anchor element, and a central section extending between the first and second end sections of the second web. At least one lining table is disposed at circumferentially outer portions of the first and second webs, and a pin or other return spring mounting is provided by at least the first web. The brake shoe is particularly configured so that a brake shoe return spring, which is connectable to the return spring mounting, is positioned so that a center line of the return spring is offset from an axial center line of the lining table but located axially inboard of an outside edge of the second end section of the first web.

A system and method for evaluating characteristics of an S-cam are provided. The inventive method includes the step of obtaining angle values and displacement values indicative of an angle of rotation of the S-cam and displacement of a cam follower caused by rotation of a lobe of the S-cam. The method further includes the step of determining a profile for the lobe of the S-cam responsive to the angle values and the displacement values. The method further includes the steps of computing a deviation of the profile from a desired profile for the lobe of the S-cam and determining a rate of change in the deviation of the profile. In addition, the system and method may evaluate characteristics such as the concentricity of the S-cam and power transfer characteristics of the S-cam.

A wheel end assembly is provided that allows venting of pressurized air from a chamber defined by the hubcap, but prevents entry of contaminants into the chamber. The wheel end assembly includes a hubcap that is configured to be coupled to a wheel and defines a chamber for retaining lubricant for wheel bearings for the wheel. One wall of the hubcap has an aperture in fluid communication with the chamber and a plug is disposed within the aperture. The plug defines a valve for releasing pressurized air from the chamber. The assembly finally includes a cap that is supported on the body of the plug and extends in an outboard direction. The cap is disposed over an outlet of the valve and defines a first fluid chamber in fluid communication with both the outlet of the valve and ambient air. The cap and plug can be inserted into and removed from the aperture as a unit.
