Brake pad steel backing plate types

Brake pads are a component of disc brakes used in automotive and other applications. Brake pads are composed of steel backing plates with friction material bound to the surface that faces the disc brake rotors. Good quality disc brake pads are composed of 3 major parts, steel backing plate, friction material, production quality control.

What is a brake pad steel backing plate?
In a disc brake design the friction material, also called a friction block or “puck” is attached to a brake pad steel backing plate with rivets, adhesive, or a newer NRS™ mechanical retention system. The steel backing plate is made from steel plate and transfers force from the brake caliper piston evenly across the backing plate to apply the friction material to the brake rotor.

Stamped hole backing plates
Brake pad backing plates with holes are also called stamped hole backing plates or punched hole steel plates. They are widely used backing plates for car brake pads and medium, heavy duty truck trailer brake pads. Now, more than 95% of passenger vehicle brake pads are made of stamped hole back plate. However, for commercial vehicle (CV) brake pads, it’s not a best choice to use stamped hole backing plates. We advise to use wire mesh back plate, cast iron back plate, or NRS back plates. Because these back plates can get much better shear strength.

Wire mesh backing plate
Generally, Wire mesh backing plates are also called steel mesh backing plates or weld mesh steel plates. They are widely used backing plates for medium, heavy duty brake pads. Wire mesh steel plate is constituted by steel wire mesh welded to the backing plate to help provide mechanical retention for friction material. The Wire mesh steel pattern can increase shear strength and pad life, so they are widely used in commercial vehicle’s brake pads. Wire-mesh backing plates can provide better shear strength than hole steel back plate, but price is a little higher than stamped hole back plate.
