Memory Steer, brakes grabbing all four corners

[bigrigdually]

I posted this but didn't get much response. I replaced the front ball joints and checked all tie rod ends ect and everything is tight. I took it for a ride and I can't keep it straight. Someone said its memory steer and the ball joints need time to set. Also I replaced all the calipers, rotors and pads did a ps flush and vacuumm bled all the brake lines. Took it for a ride and after a few miles of driving and breaking caused the brakes to grab and not let go. Took all I had to get it home and once back the breaks were smoking hot all four corners.

What do you think?

did you go to a shop and have the alignement done.
when i did my ball joints and tie rods my alignment was wayyyy off.

Did you notice weird steering symptoms after replacing everything? I'm just not sure if the alignment will solve this wonder. And my brakes are still acting up bad.

I have the same problem with the brakes. And I changed all four calipers pads and rotors. Were your slide pins all froze up on you? A few people told me that the ABS module would be the part to change out. But they are $700 plus the core change..... HA. It's ridiculous. I'm just waiting until I find one in a junk yard.

When I did my brakes I had to grind the paint off of the pads to stop them from sticking in the slides.

I don't think my truck has abs. There are no sensors anywhere on the hub or brake area. The paint on the pads would make sense. The fronts were a little snug going in but the backs slipped right in. So for all the brakes to grab would throw that theory out the window. I could see if it was only the fronts but it's not

my slide pins were rusted out and sticking. I landed up putting all remanned assemblies on the front because it wasn't worth doing the parts individually. But it sounds like this may be your problem. I'd definitely clean them, and then test the spring's ability to push the pin back out. Otherwise they will stick.

I've never heard of memory steer before (but who am I??). I think you're having a serious alignment issue. Do you notice vibrations when driving especially at higher speed and matching the speed you're travelling at? Have you had your tires balanced, rotated, and aligned? If you were out to begin with you'll have uneven tread.

Do you have a track bar or steering stabilizers if you're lifted?

I mean my old calipers I had to beat off with a sledge hammer so ya they were frozen. Could new calipers have frozen pins right off the bat?

No lift, brand new tries just mounted and balanced awaiting alignment. Problem is I can drive it to the shop to get aligned cuz the brakes lock up..can't win with this one. I havnt been able to drive it far and feel for vibrations but it seems smith to me

Did you replace the rubber lines yet? Sometimes they get internal tears and act like check valves. and you don't have that wire on the fronts?
