brake bleeding tips
Posted 02 November 2003 - 08:50 PM
Do you stomp the pedal hard for each wheel till it hits the floor?

2. remove master cylinder reservoir cover and fill with brake fluid.. reinstall cover.. check fluid often while bleeding to prevent fluid from getting too low and allowing air bubbles into master cylinder.
3. have someone there to help, as well as a supply of new brake fluid, empty plastic container, rubber or vinyl tubing to fit over bleeder valve and a wrench to open and close bleeder valve.
4. beginning at right rear wheel, loosen bleeder screw slightly, then tighten it to a point where its snug but can still be loosened easily.
5. place one end of the tubing over bleeder screw fitting and submerge the other end in brake fluid in the container.
6. have assistant push down on the brake and hold pedal firmly depressed.
7. while pedal is depressed, open the bleeder screw just enough to allow a flow of fluid to leave the valve. watch for air bubbles to exit the submerged end of the tube. when the fluid flow slows after a couple of seconds, tighten the screw and have assistant release brake pedal.
8. repeat steps 6 and 7 until no more air is seen leaving the tube, then tighten bleeder screw and proceed to left rear wheel, and the right front wheel in that order and perform same procedure. be sure to check fluid in master cylinder regularly.
9. dont use old brake fluid.
10. refill master cylinder after you've finished..
11. check operation of brakes. pedal should feel solid when depressed.

The bleeder screw has a hose you just attached to it, going into a bottle of brake fluid. This is how you keep air out of the bleeding process. Make sure the bottle can't tip over. A clear hose is best, as then you can tell when the old brake fluid is gone and only new fluid is in there.
You will be under the car, loosening and tightening the bleeder screw as needed. You friend should pump the pedal about 5 times while you have the bleeder screw loose, holding the pedal down on the last pump. You then tighten the screw. He/she tops off the master cylinder. Repeat until you see only clear fluid AND friend tells you the pedal effort has increased a lot. Then go to next brake.
Dang, Blue Train, you posted while I was writing mine!

Never pump the pedal while the bleeder valve is open, you just suck in air or old fluid and defeat the purpose.
I also never pump the pedal. Always use slow strokes up and down to avoid small bubbles in the fluid.
I highly recommend the cheap little one-man bottle bleeders, they work great.
I also think that Subarus should be bled in a cross pattern, but it's not critical.
Keep in mind if you replace the pads, the reservor will be low untill the pistons are screwed back out, then the reservor will fill back up. If you add fluid and screw the pistons back out, you'll have a mess.

Of course, slow pumping. Shoulda specified that.

This is is why I prefer the "one man" system, with a valve in the hose going into the bottle. I can push the brake pedal myself!

. As always the advice is much appreciated and you should all feel safer driving out there knowing I have brakes again!
