Since my car has abs do i have to bleed them a certain way. I cant seem to get all the air out of them. I have done many brake jobs befor but i just cant seem to get all the air out. I have no brake pedal and I know its not the master cylinder because it working before I took the calipers off.

I know when I installed new calipers I had the same problem! I had to bleed the master cylinder on both vlaves and then bleed the calipers. There should be a couple of bleeders on the side of the master cylinder where you add fluid. Bleed them first. The ABS module must swallow some air when a caliper is pulled????? Get a one man bleeder kit from local parts store for like $10. Not so much that you don't have help, but they are great for a clean work place. No mess with fluis squirting accross your fender! I don't care what they say, I never re-use the fluid!

Just a stupid question here....

you didn't get the calipers crossed and put them on the wrong side did you? I did this on my brake install, I was in a hurry and I got them on the wrong sides. When you do this, the bleeder is on the bottom instead of the top of the caliper, which traps air in the top of the caliper. I bled the CRAP out of them, and it had no brakes at all... until I figured out WTF i did wrong.

as long as you didnt let your master cylinder get completely empty and didnt mess with the ABS module at all the ABS shouldnt have air in it. what method did you use to bleed the brakes?

as for bleeding them a certain way you should go from passenger rear to driver rear then passenger front then driver front.

When I tok them off I left them both on the side ha hey belong on, so im certain that they are on the right side.The only thing that I can think of is that I had fluid to low on the master cylinder when I was bleeding hem and it sucked some air into it.IF thats the case,ill re bleed the master cylinder, but there aren any bleeder valves on the absblock is there?

no im not sure how to do it on a mustang but i know some vehicles you have to hook up a scan tool and run the ABS module so the valves move in it and moves the air through the lines so you can bleed it out the calipers.

sh*t thats what I was thinking but hoping not to hear

Ehhh WRONG! TWO STRIKES FOR YOU! Yes you can get air up into the ABS solonoid. All it takes is for you to turn the ignition to the acc position or start the car to release the pressure of the pedal, which is the only way to figure out that you have no brakes! No scan tool is needed. What are you talink about? I had the same problem and my master cylinder did not get too low!

I told you how to do it yet you haven't listened. Bleed the master cylinder first and then bleed the front calipers. Do the rear after the fronts and then do the fronts again!

targa if you dont let the fluid get too low in the master cylinder then you wont have air in the master cylinder unless you fuked with it meaning no point in bleeding it!!the only way the ABS module will get air in it is if you replaced it, fuked with it, or let the master cylinder run too low. and judging by the comment you left earlier saying how the ABS must swallow air followed by a **** load of questin marks im guessing you dont know much about ABS systems and bleeding them possibly not how they work either. when bleeding them you need to get the valves in the module to move pushing the air out of the module and back into the brake lines so they can be bleed out through the calipers.going in through the computer system and telling the valves to move is the easiest way to do that.
