Question

Technician a says the size of the pads, shoes, drums, and rotors is based on the weight of the vehicle. technician b says their size is based on the top speed the vehicle can achieve. who is correct?

O A only
O B only
O Both A and B
O Neither A nor B

Answer 1

Technician A is correct in that vehicle weight is a primary factor in determining the size of brake components; however, top speed, mentioned by Technician B, also influences their sizing to a lesser extent. Therefore, the correct option is a.

Step-by-step explanation:

Technician A states that the size of the pads, shoes, drums, and rotors is based on the weight of the vehicle. This is indeed a primary factor because heavier vehicles require a larger friction surface area for effective stopping power. On the other hand, Technician B suggests that their size is based on the top speed the vehicle can achieve. While the potential speed is also a consideration, especially for performance vehicles, the primary sizing factor is typically vehicle weight and the demands of normal operating conditions. Therefore, Technician A is correct and Technician B is also correct to a lesser extent, as both vehicle weight and speed potential can influence brake component sizing. However, the question seems to focus on one primary factor over the other, so if we must choose one technician who is more aligned with the most common criteria for brake size specifications, we would side with Technician A.
