Commercial Driver License (CDL) Class B Practice Test

If your brakes feel spongy while driving, the recommended action is to inspect the brake system immediately. Spongy brakes can indicate an issue such as air in the brake line, low brake fluid, or a failing master cylinder, all of which can severely compromise your vehicle's stopping power. Taking immediate action is crucial to ensure safety, as driving with compromised brakes increases the risk of accidents. Continuing to drive with spongy brakes can lead to more dangerous situations, as you may be unable to stop the vehicle effectively. Quickly braking to test the system may not provide a reliable assessment and could worsen the problem if the brakes are already failing. Engaging the ABS (Anti-lock Braking System) is useful in certain situations but does not address the underlying issue of spongy brakes, which requires inspection and potentially immediate repair before continuing to drive safely.
