Brake Woes/ recall fix on Work Horse 22P

Have you flushed brake fluid like they told you to do on the recall? I had my recall done in 9-09 and have not had any problems since. The moisture buildup in the fluid will cause corrosion in the metal parts of the brakes. I have flushed my fluid 2 times since the recall. 3 weeks ago they said the fluid looked very clear yet but did use 1.5 L to flush the entire system. The previous one I did with my son on the driveway.
