When I bled mine, I did a complete total flush...I burned through the whole 32oz. My car, at 85k+, Did have a noticeably firmer pedal.. But my brake fluid came out looking like a...well almost coke colored, after only 3 years...
YMMV

Perhaps you need to replace the brake fluid in your 10 year old car.

as a matter of course, I have bled my 2014 brakes twice, about every 75,000

I think its just something you should do
