I would consider this job half complete. Bleed the old fluid from the caliper bleeder screw. The Gen 2 Astro/Safari Vans do not require the wheel to be taken off, not sure about the gen 1s. This would add 10 more minutes to the job. But yeah suction pump is a fantastic idea for the DIYer
Hey I have a question. I'm from Germany and I just bought a US Import chevy g20. It has the same reservoirs as yours. The small one is completely empty. I don't see anything leaking or stuff. Do you know why this could happen? The top one is filled tho. With good and clear fluid.
Sometimes small leaks inside the wheel cylinder itself will not show up. The rubber end caps will hold the fluid and the brake dust will absorb the minute leak. As the leak gets worse it will eventually show up and run down the inside brake drum and onto the tire. ON disc brakes you should be able to spot a small leak. Otherwise, the master plunger may be the culprit. Keep in mind if you are having to keep adding brake fluid then there is a leak somewhere. I once found a leak behind the brake booster on the firewall inside the cab, so you may want to check that as well. Thanks K.M.H.!
Thanks Steve, I like the home made pump set up, can I use a jug from1/2 Gal. of whole milk.??...Lol
Either one will do unless you are lactose intolerant.

I used a Turkey bastor to suck out the old brake fluid.
Turkey basters work very well! Thanks for the comment!
that fluid did look pretty dirty, I guess when it gets that bad , it needs changing.
It's a good old van and I just overlooked it. No telling when the previous owner had something done like this.
