Alright, several months ago my brakes were pulling the car extremly hard to the left when I pressed the pedal. So I changed everything from the wheel bearings all the way to the firewall. This seemed to help until recently. Bearings, rotors, pads, calipers, lines, prop valve, power booster, master cylinder, check valve. $350 of stuff. The only 2 things I didn't change are the hard lines from the prop valve to the flex line at the caliper and the 2 caliper slide pins/ bolts. Over the past few weeks, I have noticed the pulling again (not so bad though) accompanied by a horrible squeal. There is a lot of brake dust on the driver rim and not so much on the pass side. What is going on?? Should I change the slider pin/ bolts? Can the pad be hanging up on this?? I don't have any leaks anywhere, it is dry under the car. This is driving me nuts! There is plenty of fluid flow out of both lines. I have done 4 wheel bleeds. I don't know what to do next. Please help!! Thanks!

For what ever reason? you are definately not getting enough pressure to the front passenger side. Is it possible that the hardline running to the passenger side front caliper is exposed to heat from possible aftermarket headers install, etc? the fuild could be boiling on that side and creating air and water in the line, thus dropping line pressure. Or maybe you just aren't getting all the air out when you bleed them. When you stated you have replaced lines already, I am assuming that you put new hoses on (braided or rubber, doesn't matter as long as they were new hoses and not used). An old hose can also cause pressure blockage.

Everything is stock ( no headers or anything). I went ahead and pulled it all apart again today. I bought some new slide bolts and installed those. I also bought some of the brake squeak grease. That has seemed to cure it , for now. I drove it for a while after I did it and no pull or squeak happened. Would the rear brakes cause it pull any? I thought about that on my way home today.

Yes the brakes lines are new rubber ones.

Thanks, if it starts again, I will look further.
