The chatter plate hails back to the days of asbestos brake pads that would harden up over time and cause the pads to squeal. The chatter plate was an anti-vibration device to reduce that squeal. When federal law banned the use of asbestos, the new pad compounds didn't harden up like they use to so the chatter plate became redundant. You will not be able to find any aftermarket brake pad maker that includes the chatter plate.
Our brake pads have the correct thickness for replacing the chatter plate style pads. Our special pad compound has slightly less metallics than others because some aftermarket pads were found to be damaging rotors.
