Manitoba Airbrake Practice Exam

Air brake chambers are located at each wheel on both sides of the vehicle. This is because the air brake system works by using compressed air to activate brake pads or shoes at each wheel. Placing the brake chambers at each wheel allows for a more equal distribution of braking power and improves the overall braking performance of the vehicle. Options A and B are incorrect because they only mention one specific side or set of wheels, which is not accurate. Option D is incorrect because it specifies only the driver's side wheels, when air brake chambers are located at both the driver and passenger sides. Therefore, the correct answer is C because it accurately describes the location of air brake chambers on a commercial vehicle.
