bleeding brakes.. question about ABS module... I've done my research and searched through this site, and the other one as well, but I had one question about bleeding the brakes *and* the abs module.
I have seen it posted that in order to bleed the abs module you should get the car over 6 mph, and bleed the brakes with it still running. What I want to know is, after the car is running and has gotten above 6 mph, do I hit the brakes hard enough to trigger the abs or should I not trigger the abs before I bleed the brakes?
I hope I'm being clear..
The reason I am thinking I've got air in the abs module (not sure if I do or not) is because I had some work done on the car and the place that did it had to replace the left rear stainless hard line that goes across the axle. (They replaced it because they cut it accidentally with a grinder. ) They may have let the reservoir/master cylinder run dry. They did bleed the brakes and they feel good, except today when I hit the brakes on the car for the first time, the pedal felt a little squishier than normal. Thought I'd bleed the abs module and the whole system to be sure.

Re: bleeding brakes.. question about ABS module... The consensus is ...
Something over 6mph
initiate an ABS event
don't turn the car off
bleed all 4 corners
When chasing an air bubble up close to the MC, I've heard it's best to bleed in just the opposite direction ... LF, RF, LR, RR
This is so that you push the bubble down stream at all times.

Re: bleeding brakes.. question about ABS module... bleeding both the front and the rear at the same time helps remove the bubble quicker. Dont worry about bleeding the ABS module, its one of the donts when bleeding the brakes. Stick to bleeding the calipers only <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Re: bleeding brakes.. question about ABS module... G2LS1:
What do you mean "bleeding the abs module is one of the donts"? - Should I just bleed it the way I described?
Also, bleeding the front and rear at the same time - do you mean (for example) the front left and the rear left at the same time, then the front right and rear right simultaneously?

Re: bleeding brakes.. question about ABS module... Some people bleed the ABS module itselft. Bleeding the way that you described previously will get the job done fine <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
As for bleeding the front and the rear the same time, You got it! RR and RF....then LR and LF <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />
