If spongy brake action is not caused by air in the brake system, what is the next most likely cause?

Incorrectly installed brake linings
Deteriorated flexible hoses
Low brake fluid levels
Faulty brake disk

The correct answer is: Deteriorated flexible hoses

Spongy brake action is often a result of air in the brake system, which can compress, causing the spongy feeling when the brakes are applied. If air in the system has been ruled out as the cause, the next most likely reason for spongy brake action would be deteriorated flexible hoses. Flexible hoses in the brake system can deteriorate over time, leading to a loss of brake pressure and causing a spongy feeling when the brakes are applied. The incorrect installation of brake linings, low brake fluid levels, or a faulty brake disk are less likely to cause spongy brake action compared to deteriorated flexible hoses.
