Why is Hyundai Elantra's brake pedal spongy or soft?
Hey there, sorry to hear you're having issues with a spongy brake pedal on your Hyundai Elantra. I've dealt with this kind of problem before, and it can be pretty unnerving. There are a few things you might want to check out. First off, one of the most common causes is air trapped in the brake lines. If you've recently had your brake fluid changed or the system opened up for any reason, air could have gotten in there, which messes with the hydraulic pressure. Bleeding the brakes might help clear that out.
Another thing to consider is the brake pads. If they're worn down, they won't grip the rotors as well, which can make the pedal feel soft. Also, don't overlook the master cylinder—if it's leaking internally, it won't be able to build up the pressure needed to give you a firm pedal. I've also heard that old or contaminated brake fluid can be a culprit since moisture in the fluid can cause it to vaporize under heat, making the pedal feel mushy.
Lastly, check the brake lines themselves for any signs of wear, corrosion, or leaks. Even a small issue there can cause big problems with your braking. If you're not comfortable checking these things yourself, it's definitely worth getting a mechanic to take a look. Better safe than sorry, especially when it comes to your brakes. Hope this helps!
