Interesting that I got one reply saying change at intervals, another saying ride them as long as they perform well. I lean towards the latter.
I was really interested in a universal procedure. Would it work to 1) screw funnel into port on hood 2) remove caliper and let it hang with bleeder at bottom 3) fill a syringe with new fluid and pump it into open bleeder to displace old fluid 4) Close bleeder, plug and remove funnel and reinsert plug on hood?
How will you discover they don't work? Most likely when you try to use them on the road. This is why we have service intervals for cars and motorcycles, so you maintain these systems and they always work properly. Would you run your car til the engine blows up then change the oil? Along with rebuilding the engine? I can't understand why people are too lazy to maintain things, especially important things like brakes.
