New Jersey Air Brakes Test 2025 – 400 Free Practice Questions to Pass the Exam

Question: 1 / 400

What may indicate a malfunction in the air brake system while driving?

Increased vehicle speed

Unusual noises from the brakes

Unusual noises from the brakes can signify potential problems within the air brake system. These noises may include grinding, squeaking, or hissing sounds, which can indicate issues such as worn brake pads, air leaks, or problems with the brake components themselves. Recognizing these sounds allows a driver to take appropriate action before further damage occurs or before encountering hazardous situations on the road.

Increased vehicle speed may not directly indicate a malfunction in the brake system; it can occur for various reasons, often unrelated to braking performance. Similarly, flashing headlights and vibrations in the steering wheel can result from other mechanical issues or driving conditions but are not specifically indicative of problems with the air brake system. Thus, the presence of unusual noises serves as a clear warning to the driver to inspect the braking system more closely.
