2003 Kia Sedona Q&A
2003 Kia Sedona Question: Frequently adding brake fluid. Where should I first look for leak?
Look for the wet spot....................If no history of problems prior to wheel cylinder replacement start there. - ziptie12
You said you have no leaks? Double check. The master cylinder is a week link also. If the master cylinder is mounted to the booster, remove it. you should not see any fluid between the two. If it's wet, it's coming from the master cylinder and contaminating the booster, creating more problems. Goodluck - helpfull4u
