"The dot 5 does not absorb water so how are you going to get it in the system"
Condensation. The screw-on brake reservoir caps are not air tight. In fact, they are deliberately vented. Take a look at the threads inside the caps and (assuming your caps are like mine) you will find a channel cut perpendicularly through the threads that permits air to be exchanged between the reservoir and the atmosphere. I don't know if the later rectanglular type reservoirs are vented or not. I found that the round ones are vented when I built a pressure bleeder adapter for my bike. I had to plug the vent in my home-made adapter to get the reservoir to hold pressure. By the way, I've never had to rebuild or replace seals in any of my brake components. Ed
First problem with your thought, dot 5 does NOT absorb water so it will NOT collect water at the lowest point.
even if the system is exposed to condensation it does NOT absorb the water so it can not have a water issue at the bottom of the system.
the brake system is sealed as stated.
Since you have changed your dot 3 fluid out over the course of time you have removed the contamination in the brake system, which is a good thing, but if you had dot 5 in it you would not have to replace the fluid.
I am not wanting to start a bunch of crap but there is a better mouse trap in the brake fluid world, try it you will like it

I have since rebuilt the rear (just cleaning and new seals), adding a GSXR master cylinder and resevoir, as that is what the GSXR system uses.
The only reason I rebuilt and replaced the seals in the rear caliper is because Dot 3 or 4 is NOT compatable with Dot 5. You cannot mix them. Therefore I cleaned out all the Dot 5 and replaced the seals.

As to the dot3 and dot5 not being compatable, although I'm sure this is true, all I did was pump out nearly all of the dot3, then add dot5, pump it nearly all the way out, add more dot5 ect, until I was sure dot5 was all that was being pumped out. This way no need to bleed the system or any other headaches. Does this get all the non compatable dot3 out completely? Must be good enough, because it's been 20 yrs and a lot of miles with zero problem
