Abstract
A drum brake dust shield is provided for a vehicle braking system having a drum brake assembly. The dust shield comprises a first semicircular portion lying in a generally flat plane, and a second semicircular portion lying in the same plane as the first portion to form an annular disc. A dividing slit is defined between the first and second portions. The dust shield further comprises a hinge portion interconnecting the first and second portions. The hinge portion has a stress-relief slit that transversely intersects the dividing slit such that mechanical stresses between the first and second portions are distributed and dispersed over a relatively larger surface area when the first and second portions are spread apart along the dividing slit in opposite directions relative to each other to install the dust shield on the drum brake assembly.
