Suddenly the brake pedal when pushed went down a good deal further and then braked normally. This happened all the way home. Next being Saturday.and Kia service closed I tried the brakes, and the same thing happened but on second pump I had a full pedal and has worked perfectly since. Kia checked the system and could find no problem.

If there's no external fluid leaks, suspect internal leakage from a failing master cylinder. The problem often starts out as an intermittent low brake pedal.
