A power brake booster is a critical component of modern cars. It also goes by the names brake servo or vacuum booster. Essentially, the device significantly amplifies the braking force you apply to the brake pedal, allowing for quicker and easier stopping. If a power brake booster 178-1032 fails, it is a safety hazard and should be addressed immediately. There are at least five potential signs of such a failure.
1. Soft or Hard Break Pedal Feel
The most common sign of a failing booster is a hard brake pedal. When the device operates as designed, you should feel like the brake is easy and light to press and activate. When you suddenly need to put much more effort into pressing the brake and stopping your vehicle, the booster is no longer doing its job.
2. Delayed Brake Response
A failing booster can also increase stopping distance or present as a delayed response. When in control of literal tons of automobile suspension parts and materials, you want to understand and have control of your braking system. The delayed braking response can lead to dangerous situations, so you want to check it as soon as possible to avoid accidents.
3. Hissing Sounds
The brake booster is a vacuum system; a failing booster might create a hissing sound. The sound occurs when you press the brake pedal, and it can indicate a leak in the device’s diaphragm or vacuum hose. While the sound does not always happen in a failing booster, it represents an internal issue that needs to be investigated.
4. Rough Idle or Stalling
In some cases, a failing power brake booster can cause a vacuum leak that may affect the engine’s air-fuel mixture. If this occurs, the engine might respond with rough idling or stumbling. In severe cases, the problem can cause the engine to stall. To fix the issue, you will need to replace the booster with a quality part, like the GM Genuine 178-1032.
5. Ignited Check Engine Light
Modern vehicles have sensors installed throughout the mechanical and electrical systems. The sensors have relays that send signals back to the main computer. When an error occurs, the relay responds by triggering the illumination of warnings on the dashboard. Sometimes, the check engine light may turn on in response to a failed power brake booster. The only way to understand what triggered the light is to take it to an auto parts shop or mechanic and receive a diagnostic.
A failing power brake booster is a hazard. It can make it hard to predict appropriate stopping distance, which can cause accidents. To avoid issues with the device, you should have your vehicle and its braking system checked regularly. Also, if you suspect a problem with your brake booster or recognize any of the signs above, contact a licensed mechanic and schedule an appointment to check on the device or replace it. A mechanic can help you understand the problems you are having and is in a better position to offer guidance.
