Question about Hyundai Motor 2002 Sonata
The first thing you should check is the brake fluid level in the master cylinder. In case you are not familiar with this item it is located in the engine compartment right in front of were thr driver sits. It is usually high up and has a cap that is held on by a spring clip. Push the spring clip off to the side and lift the cover off.you will be bale to see the brake fluid level. It should be close to the top of the chamber. if if
appears low, add some brake fluid to bring it close to the top. You can get brake fluid in an 8oz can at any auto parts store. Tip: Always keep the brake fluid can tightly sealed after use. It has a tendency to absorb moisture out of the atmosphere, which can freeze in the winter.
Adding some brake fluid ( if necessary) should help the pedal problem. However..... We must find out where the missing brake fluid is going. The brake fluid system is a closed system,ie, you do not
normally have to top off the master cylinder. What this means is you have a leak somewhere in the system. Best places to look is 1.) the master cylinder. Look for signs of leakage. 2. Each of the 4 wheels. There is a braking piston on each wheel. Look for signs of fluid on the inside of each wheel.
There is one other possible cause of no brake pedal and that would be a faulty master cylinder. If you press the brake pedal and hold the pressure you shsould reach aa point where the pedal will not go down anymore. if it gradually keeps going down, I would suspect a faulty master cylinder.
Hope this helps Good luck
