Abstract
A backing plate for a drum brake system comprises an abutment plate made of strong material and a shielding plate that is lighter and is made of noise and vibration dampening material. The abutment plate attaches to the vehicle and is configured to engage brake shoes to resist braking forces. The shielding plate is preferably made of relatively this damped steel to reduce the speaker effect of the backing plate and reduce overall NVH.
