Respuesta :
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.
