technician a says all the friction components of a disc brake are exposed to the airstream. technician b says this helps to cool
Dimas [21]

Both technicians are correct because all the friction components of a disc brake are exposed to the airstream and this helps to cool the brake parts and maintain braking effectiveness during repeated hard stops from high speeds.

<h3>What is friction?</h3>

Friction can be defined as a force that resists the relative motion of two physical objects when there surfaces come in contact. This ultimately implies that, friction prevents two surface from easily sliding over or slipping across one another.

<h3>What is a braking system?</h3>

A braking system can be defined as a mechanical system which comprises various components that are designed and developed to bring an automobile vehicle in motion to a stop, when applied by a driver.

Generally, when the friction components which makes up a disc brake are exposed to the airstream, it helps to cool the brake parts, as well as to maintain braking system effectiveness in an automobile vehicle, during repeated hard stops from high speeds.
