I have a valve with a valve going to the Mazda 6 engine refrigerator

About the piece:

The brake booster is a rubber hose that carries the vacuum from the engine to the brake booster. This part is a vital component of the brake system, as it ensures the necessary negative pressure is provided to facilitate the braking process and reduce the effort exerted by the driver when pressing the brake pedal.

His job:

• Transferring negative pressure (vacuum) from the engine to the brake booster to enhance braking force.
• It has a One- Way Valve to prevent air from returning to the engine and maintain stable pressure.

Symptoms of its damage:

• Increased brake pedal stiffness : The pedal may become more difficult to press.
• Poor brake response : resulting in increased stopping distance.
• Air leak : Hearing a hissing or air sound when applying the brakes.
