Honestly, I would buy a $15 repair manual. It tells you all that in it.

How to bleed brakes on a 95 Chevrolet astro Van?

same as you would with any other car, have some one work the bleeder while you push the brake pedal and hold it to the floor while they tighten the bleeder back. lather, rinse, repeat until all air is out of system. start at the furthest wheel first and work your way to the closest wheel. NOTE; some cars have what is called an X type braking system. the astro is not one of them. but to be sure look under the van and follow the lines to the proportioning valve, if there are 4 lines then you have the normal system, if there are 5 then you have the X type system. to bleed an X system you go from the rear wheel then to the opposing front wheel, then the same on the other side.

Always bleed the brakes in the following order: Right rear, left rear, right front and left front. The best way to actually see if you have bubbles or a steady stream of brake fluid is coming out of the bleeder screws is by going to any hardware store and buying a 3 foot length of clear vinyl hose to slip over the head of the bleeder screws. Loop the hose at least two feet above the bleeder screws and fasten with a wire.

Before you start, fill the master-cylinder reservoir completely full using Dot 3 brake fluid. Someone has to be in the drivers seat to press the brake petal to the floor and say stop so the person doing the bleeding can close the bleeder screw before the driver releases the brake petal all the way out. Repeat until the person doing the bleeding can see a steady non-bubble stream of brake fluid. Refill the master cylinder after bleeding each wheel location.

i voted for joseph.
that being said it is NOT a job that just anybody can do and do it right. do it wrong and one day you'll try to put your brakes on and the petal may just go to the floor.
this is serious stuff, you need someone, preferably a mechanic.
you don't say WHY you want to bleed the brakes. usually the only time that is necessary is when you have to change one or more of the cylinders and then air gets into the lines. you bleed the brakes to get the AIR out of the system. it usually also included doing them twice just to be sure. your life depends on someone doing it right.

there should be a bleeder valve in back of each wheel cylinder. you can't really miss it, take off the wheels and look in back of your brake assembly and youll see it. The tools you'll need are

-a box end wrench
- clear plastic tube that fits snugly over your bleeder screw
-fresh brake fluid (enough to ensure your reservoir is never more than half empty so you're not sucking any air into the system)
-a jack, axle stands, any method of raising your car
-a tire iron
-water bottle filled about a quarter of the way with clean brake fluid
-someone on hand to sit in the car and pump the brakes at your command (make sure they can hear you loud and clear)

***Start bleeding your brakes with the one farthest from your master cylinder (usually thats the rear right one, then rear left, then front right and then front left but it depends on the bleeding sequence for your car).***

-To bleed your brakes, take off all four wheels (you can do it one at a time if you only have one jack and no axle stands) and make sure you can open and close the bleeder screw without breaking it. (you'll probably want to use a box end wrench, because vise grips will most likely round off the edges of the bolt.)
-fit one end of your plastic tube over the bleeder screw, and immerse the other end in a bottle about a quarter filled with clean brake fluid.
-have the person in the car pump the pedal a few times and then hold it down
-loosen the bleeder screw (about a quarter turn should be good) letting all the air and brake fluid escape through your tube into the bottle
-when no more air or fluid come out close the bleeder and tell the person in the car to release the brake pedal
-continue this process until no more air bubbles come out through the bleeder
-do it for all four brakes


****Make sure to keep checking and refilling your brake reservoir, never letting it get more than about half empty***

**** MAKE SURE you don't get any brake fluid on any painted surfaces, itll start to eat away the paint very quickly****

Once your done bleeding your brakes, fill up your reservoir and you should be good. its not difficult, i hope this helps though its pretty straightforward once you start youll see. good luck.
