When hearing air while applying brake could it be master cylinder Know fluid is leaking from wheels?

Air in the brake lines can cause a spongy feel to the brake pedal, and can also lead to a loss of braking power. When air enters the brake lines, it can compress and cause the brake pedal to travel further before the brakes engage. This can make it difficult to stop the vehicle, and can also increase the risk of an accident.

There are a few ways that air can enter the brake lines. One common way is through a leak in the brake lines. If a brake line is damaged, air can be sucked into the system and cause problems. Another way that air can enter the brake lines is through the brake fluid reservoir. If the brake fluid reservoir is not properly sealed, air can be drawn into the system when the brake pedal is depressed.

If you hear air while applying the brakes, it is important to have the brake system inspected by a qualified mechanic. The mechanic will be able to identify the source of the air leak and make the necessary repairs.

It is also important to note that leaking brake fluid from the wheels is a serious safety hazard. Brake fluid is essential for the proper functioning of the brake system, and if it is leaking, the brakes may not work properly. If you see brake fluid leaking from the wheels, it is important to have the brake system inspected by a qualified mechanic immediately.
