Hi guys, have a good look at this article I came across: http://www.ratbike.org/bbs/index.php?messageID=25324

After reading this article I went out and flushed the brake fluid out of my 84 Aspencade and could not believe how much contaminant I saw in the reservoirs after only 3 years of use. It looked like creamy yellowish mush sitting at the bottom of the reservoir and was easily removed with aerosol brake cleaner and paper towels. I even sprayed the inside of the fluid level window with the brake cleaner and can now see through it.

You can bet that I'll be making flushing and bleeding the brake system on my Wing an annual maintenance item, especially since the brake feel is much more firm and positive since the fluid replacement and bleeding.

Had I left the contamination in the system I would have been replacing the master cylinders in the very near future due to corrosion from the accumulated moisture.

And it's not like brake fluid is expensive either... I usually change mine annually, or when I notice the color of the fluid in the resevoir is getting darker.

When I rebuilt the rear caliper on my bike, I found a 20 year old accumulation of dirt inside the piston chamber, about a teaspoon full.

seems like I started a thread about brake fluid and how it works a while back.... key is, when it is no longer clear, time to change it... the most overlooked and important fluid on your bike

That's right, sir.

I've enjoyed the learning process so far with my wing. It's the first vehicle that I've owned in a long time that I actually don't mind working on.

Have a good weekend, Vic. Hope you get some riding in. I've got to work:(but sometimes I can take my bike.:D

On the subject of Brake fluid. Anybody know a good source for DOT 4? All the auto stores carry DOT 3 & Synthetic which is supposed to be 4 compatibal but I know it doesn't work as well as 4 on Bikes. I found a couple that also had old DOT 5 (though it was $$) I suppose I'll have to check with some bike shops....

I always had my brake fluid changed every couple of years. When it started to go a dark yellow I took this as a warning sign.

Belive it or not, our local grocery store carries DOT-4 brake fluid, I don't recall the brand but it was a major name maker of brake fluid, etc.
