Question

which of the following testing procedures is most likely performed to determine whether the vehicle will have sufficient stopping power when the brake lining materials are not preheated by previous stops?
a. burnish procedure
b. cold effectiveness
c. adhesion utilization
d. high speed effectiveness

Explanation:

The key here is to find a test for stopping - power when brake - lining materials are not pre - heated. Cold effectiveness testing is designed to assess how well a vehicle can stop when the brake components are cold (not pre - heated). Burnish procedure is for conditioning brake linings, adhesion utilization is about the grip between components, and high - speed effectiveness focuses on high - speed braking scenarios rather than cold conditions.

Answer:

B. Cold effectiveness
