Quizplus · Accepted Answer

Technician A is correct because the primary function of wheel cylinder dust boots is to keep dust and moisture out of the cylinder bore, ensuring the braking system works efficiently. Technician B is incorrect; while some components in a vehicle might allow for minimal seepage, it is not normal for dust boots to allow fluid seepage as this indicates a potential leak or failure in the braking system.
