changed cluth fluid using rangers method. it worked great no problems at all. my questions is can this also be done with the Brake reservoir
fluid checked it and it looks worse than what came out of the cluth reservoir

...just don't remove so much with suction that you manage to remove some fluid from the brake line(s) and create an air pocket. If it's that bad, it might be better to just bleed the system.
Brakes are easier than the clutch. The clutch is hard to bleed because of the bleeder location on top of the transmission. The brakes are easy to bleed. If the fluid in the reservoir looks bad, the brakes are way overdue for a good bleeding.
Suck as much fluid as you can out of the reservoir and replace with fresh fluid. Jack the car up, pull the wheels, and bleed them -- right rear, left front, left rear, right front. Be sure to keep topping up the reservoir so you don't pull in any air. Easy two-person job, or pick up an inexpensive pressure bleeder kit. Bleed each wheel until you get clean, clear fluid (use clear tubing, so you can see the fluid as it's coming out).
OF course you can just replace the brake fluid in the reservoir, but since the brakes are easier to bleed than the clutch, I would go ahead and bleed the whole brake system.
Unless you use a Tech2 machine though you won't get the fluid out of the ABS module. A complete bleed job needs to be done by a dealer or someone with the proper equipment.
One way to bleed the brakes is gravity bleed. Open the bleeder(s) and let gravity take over. Just make sure you keep the reservoir filled while the fluid drains out. Works great no air!
well its about 35 degrees here so i might have to take it to GM.
what will these guys charge for this $$

Ed,
They will charge way more than what it would cost for you to do it yourself. Unless you are having the "Tech 2" bleed done which actuates the ABS system (ask your Chevy dealer if they even do that kind of bleed; some don't), any decent mechanic can do it for you.
IMHO, don't waste your time just changing the reservoir fluid. Brakes won't refresh themselves like the clutch does because the system is too big and pipes are too long. Just have them bled properly and you are good to go. You don't want to be roaring along next spring or summer, do a few hard stops, and then when you really need them be thinking as the brake pedal hits the floor and the car refuses to stop, "Gee, I guess I SHOULD have gotten the brakes bled." It's kind of like the old joke: What's the one thing you never want to hear your doctor say during an operation? "Ooops!"

I would just go ahead and have the system flushed. BTW you don't need a tech 2 to get the air out of the ABS unless you have something really wrong during the bleeding. As long as you have enough pedal pressure to get the car to trickle the ABS it will purge the air for you. Of course it will push the air out to the calipers and you will need to go back and bleed them again, but it will save you quite a bit of money.
