When you push on your brake pedal, you should find your vehicle easy to stop. But at some point, you might notice stopping takes much more pressure on the pedal than it used to. When it gets to that point it becomes a safety issue, and you should bring your vehicle in so we can track down what’s not working correctly.
Brake pedals that are stiff mean there’s something wrong with one or more components of your entire brake system. For example, it could be moisture has contaminated your brake fluid, making it harder to push the pedal down.
Many vehicles use hydraulics to amplify your pedal pressure to a force strong enough to stop your vehicle. Certain problems can develop with your hydraulics, such as a faulty master cylinder, a kink in one of your brake lines, or a failed proportioning valve which regulates pressure to your rear brakes. Vacuum leaks can also make your brake pedal hard to push. Another cause could be a problem with your vehicle’s brake booster or its check valve.
Because your vehicle’s braking system is made up of many different components, one of our technicians will look at several different possible causes in yours. Your vehicle may not have enough brake fluid in it, so they’ll check the level. A visual inspection of your hoses, brake lines and vacuum line to the brake booster may turn up the root cause of your issues.
Because there are many different causes of a hard-to-push brake pedal, solutions may involve one or more different steps. Keep in mind this is one problem that needs to be fixed for you to drive safely. That’s why it’s important to have a professional track down the issue, or issues, and take care of the problem(s) so you can be back on the road, safely going and stopping.
