My son called me two days ago, brake pedal went to the floor on his '02 Golf. Fluid reservoir empty. He limped it to a mechanic he knows, although not our first choice, to see what's wrong. We had a discussion about how to proceed, depending on what's wrong. Brake line? Booster? failed front caliper (rears are new)? If it's anything serious we'll pony up for the 120 mile tow to our guru. But at 510K with disappearing rockers, one wonders when to stop.
However, he prefers driving the MKIV to his Sportwagen. And it gets much better FE. It's hard to say good bye to these cars.
