What is the result of vapor lock in the brake system? ) The brake pistons in the brake cylinders can become plugged due to the dirt absorbed. The brake fluid expands as a result of heat in the brake system. Consequently, the friction material will glaze. The vapor bubbles formed are compressible. As a result, the power of the brakes is reduced.

The correct answer is: The vapor bubbles formed are compressible. As a result, the power of the brakes is reduced.<br /><br />Vapor lock occurs when the brake fluid in the brake system absorbs heat and turns into a gas. This gas can form bubbles that are compressible, reducing the effectiveness of the brakes and leading to a decrease in braking power.
