    Brake Booster Vacuum Hose Leaks – Repairs in Hamilton

    What is the brake booster vacuum hose?New brake booster hoses in Hamilton

    A brake booster (or vacuum booster) is attached master cylinder setup that is used to reduce the amount of pedal pressure needed for braking in your car It achieves this by creating a vacuum to overcome fluid pressure in your car’s braking system. This improves the safety of your car’s brakes by allowing you to stop quickly when you need to.

    The brake booster vacuum hose (or vacuum line) forms a connection between the master cylinder and the brakes, allowing the brake booster to function correctly. If it splits or develops a leak or tear, you will most likely notice that your brakes aren’t as responsive as they should be.

    Symptoms of a damaged / leaking brake booster vacuum hose:

    Problems with the brake booster hose can produce the following symptoms:

    • Brake pedal difficult to push – The most common sign of a brake booster leak is your brake pedal feeling “harder” than normal. It will require more force to work and increase your stopping distance.  If you notice this, you should get your car inspected/repaired as soon as possible. This is because it can affect your safety.
    • Rough idle – A leaking brake booster hose could also cause your car to idle roughly due to a vacuum leak and excess air entering the intake manifold. This will result in excess noise and vibrations, as well as higher RPMs while idling.
    • Dashboard warnings – Depending on your car’s make and model, a leaking brake booster hose may produce a warning on your dashboard. This warning will store a fault code which provides more information about the nature of the problem.
    • Whistling noise – You may notice an audible whistle when the brake pedal is pressed. This is caused by air escaping the vacuum.
