You get into your BMW only to find that the brake pedal is stiff and hard to press. While your brakes might still function, it is still more difficult to slow or stop and it feels as if your brakes might stop working at any moment. What could be causing the brake pedal to be hard to push like this? Let's take a look at some of the common causes.
You rely on your vehicle's brake system to slow down or stop when you need to. Any issue with the brakes is a cause for concern and should be taken care of at the first sign of an issue to avoid getting stuck with failing brakes while on the road.
Brake systems on BMW vehicles work using a vacuum assisted through a brake booster. The vacuum helps to multiply the force you apply to the brake pedal to make it easier to brake and give you more control of how quickly you slow or stop. If you find that your vehicle's brake pedal is hard to apply pressure to, there may be an issue with any of the following:
- Bad brake booster - a bad brake booster can mean that the vacuum isn't working, so basically you don't have any assistance while braking
- Vacuum hose is leaking - a leaking vacuum line hoses can lead to a decrease in the effectiveness of the vacuum as a whole
- Check valve malfunction - a malfunctioning check valve can cause issues with air exiting the brake booster
- A brake booster installation problem - an illfitting brake booster or poorly installed brake booster can cause this issue as well
