Question: 1 / 400

When testing brake performance, it's considered a major defect if:

The service brakes fail to stop the vehicle

The spring brakes fail to hold the vehicle in place

Both A and B

When testing brake performance, a major defect is considered when both the service brakes fail to stop the vehicle and the spring brakes fail to hold the vehicle in place simultaneously. This means that option A alone would not be a major defect as long as the spring brakes are working properly. Option B alone would also not be a major defect if the service brakes are functional. Option D, although it is important for brake safety, is not a major defect in this context as it does not directly affect the vehicle's ability to stop or hold in place. Therefore, the correct answer is C.
