rhysoul nailed it on his suggestions. If a dealer ever tells you that you need to replace with only Kia parts to keep warranty valid, according to Federal law The Magnuson-Moss Warranty Act makes it illegal for companies to void a warranty or deny coverage under the warranty because an aftermarket or recycled part was used. If they do tell you this, they are required by law to give you said part for free.
Regarding brake flush, buy a cheap turkey baster syringe. This works for power steering fluid as well. Put open end of baster in reservoir and pump bulb end of baster to extract fluid (brake or p/s fluid) until no more fluid in reservoir. Fill to line with fresh new brake or p/s fluid. You won't get any of the old fluid out of lines to brakes and p/s pump but removes much of the dirt in the system. Less contaminated. Good luck!
