brake fluid flush/bleeding... Do it yourself??

I have 128k on my max now and i believe i still have the original brake fluid in the car. Ive added some at times in the past when it looked a little low. Besides that ive never once had this done. So should i have this done or is it easy enough for me to do myself. Im very mechanically inclined, its just ive just NEVER messed with brake bleeding before. And will i notice a difference in braking once the fluid is changed?

So any reccomendations for fluid brands amd how to bleed the system would be great!

ALSO: im having my drivers-rear caliper replaced cause mine seezed on me. My shop told me that its not necessary to bleed to system if hes just swapping out the one caliper. Any input on this?

thanks fellas,

Ant

Time to flush out your brake fluid.

If a caliper is replaced, obviously that caliper needs to be bled, not neccessarily the whole system, but since you have never done it... Just bleed each corner, takes no time at all.

Things you will need

1) brake fluid, I like the Valvoline synthetic stuff that Pep Boys sells, $5 for the large bottle, 1 bottle should be enough for the entire system
2)brake bleeder kit, $5, basically a clear tube attached to a little cup
3)a friend to push down the brake pedal

Pop the hood, and unscrew the cap to the brake fluid tank. Attach clear tube on the bleeder kit to the bleeder screw located on the caliper, open the screw 1/4 to 1/2 a turn (you will see the fluid fill the tube). With it open, have your buddy push down the brake pedal, slowly until it goes to the floor. Once he says its down, close up the bleeder screw, tell him its closed and to bring the pedal up. Repeat this procedure a few times, remember to check the level of the fluid under the hood. Just keep refilling, bleeding, refilling and bleeding. Do this for every caliper, and you system will be flushed.

Its easy...

Furthest caliper to closest caliper (in relation to master cylinder)

1 pass rear, 2 driver rear, 3 pass front, 4 driver front

This is how its "supposed" to be done

No friend needed if you buy these.

www.speedbleeders.com

I just put them on two weeks ago. Did the whole job by myself in about 1 hour.

I always heard to bleed from furthest to closest to the master cylinder.

you are right, my post is edited

I'm pretty sure with newer cars, like ours that the order of bleeding doesnt matter, as newer cars have seperate lines. But the correct order is furthest to closest...

Actually mitch,

I did some googling (is that a verb?) and found some sites that do support closest to farthest. I guess it doesn't matter if you do a full flush of the master through each of the calipers.
