material fastened to a metal

backing plate?

A) Steel

B) Wood

C) Friction

D) Oily

D) The brake pad has a block of friction material fastened to a metal backing plate.

Explanation:

A brake pad backing plate is designed in such a manner that it resists rust and maintain the adhesive bond between the friction material and plate over its entire life. Also, a brake pad backing plate must maintain dimensional stability. The brake pad has to be constructed quite well since It is a crucial as well as critical component in a brake system. A block of friction material meets all these characteristics and thus preferred as a material in brake pads.
