I do this on all my cars, will lengthen the life of your core brake parts (master cyl, calipers, etc) as brake fluid absorbs moisture. I have a motive brake bleeder so it is an easy one person job.

Did a brake fluid flush at 24k miles. Alpha was 4 years old, and even though low miles, brake fluid absorbs moisture over time so don't base it on mileage.

I think someone else here said they used a turkey baster to remove all of the fluid in the resevoir everytime they changed the oil(?) or brakes, don't remember which. His reason was although he didn't remove all of it a large portion was removed and refreshed. I have been on the fence about this. Great use of a kitchen tool but I don't know if it leaves enough old fluid(and water) in there to make much of an improvement.

Since brake fluid doesn't really circulate, I don't think that would be a very effective practice. The problems arise from moisture in the fluid that sits in the calipers and master cylinder. Unless the bleed fitting is loosened, little of the new fluid from the reservoir can get to the caliper by random frictional action in the lines. And by the time it does, its probably resaturated with moisture.

With vacuum bleed devises, changing fluid is now pretty easy without a helper.

I did it on the H3 at 5 yrs, and on the 308 at 25 years, but the old fashioned way with my son pumping the pedal. When I had my Audi, they flushed the brakes as part of the covered 40K mile service.

Great video on changing the break fluid, thanks for the link! I'm new to doing my own car work so stuff like this is great for me. Does anyone own a brake bleeder pump like that and can recommend what brand and model to get?

I have a Sears vacuum/pressure gauge test kit that I use and works great and was less than $100. If you are putting together a collection of maintenance tools, it would be a great addition for your garage.

The rubber plugs that come with the kit will also be very handy when it comes time to swap out your truck's radiator and are wondering how to stopper the disconnected transmission cooler lines!
