What can cause pulling while braking besides bad right caliper

My 2011 JKU was pulling very hard to the left when braking at any speed over 30mph. It was so bad I could brake and the jeep would pull into the next lane. Mechanic found my tie rod end drivers side had play so we replaced that. He also found the front passenger side caliper was almost seized. Took my body weight to spin the wheel. He replaced the calipers and brakes on both sides. It now brakes fine on city roads but still pulls when braking at highway speeds, I'd say over 50mph. He did an alignment and said everything was good. I believe two things were just out of range but by so little he didnt consider it to be bad. I can post a pic when I get home.

What else can cause this that I should have checked?

Does it have a lift? Check the brake lines also

Did you do something to it? Mechanically or on a trail?

Replaced all 4 calipers or just fronts? Could have a bad rear caliper if they werent replaced.

i'd first check to see if indeed the new front caliper is working correctly,
yea I know sounds dumb
but its not unheard of to get bad new parts
if the caliper checks out ok the next unit up stream is the proportioning valve/block of the ABS module

I thought I replied but it doesnt look like it went through or the site isnt loading properly for me. I'll answer them again just in case.

No lift. Upgraded track bar, dampener, tie rod and control arms (these arent upgraded just new OEM replacement).

Tires are 33x12.5x15. Have had them for about 2 years. This problem is recent.

No hard driving.

They didnt check rear calipers but would that cause hard pulling? I could see a slight pull from rear but not lane changing.

I'll have them check the fronts again. And also the brake lines. Might be cheap enough just to replace the rubber lines just to be sure.

Are any lights on the dash illuminating when it happens? Could be the stability control acting weird.

Buddy of mine had this same issue last week and it turned out being his brake line but he did put on a lift. I doubt the rear calipers would cause this because I had a seized rear and didn't know it until I changed my brake pads.

The ABS and stability control lights ome on if I try stopping 60 to 0 like you would if a car cur you off. Normal braking, they dont come on. I think they come on because the system thinks the jeep is skidding because the right tire isnt braking as much as the left.

I think I'm going to flush the system, replace the lines and add new fluid. See if that helps.

If your getting lights check the wiring on your wheel speed sensor on that side.

If its pulling to left when braking the right side front brake line most likely is pinched or the rubber brake line to caliper is restricted.

Is your jeep pulling to one side when braking? Usually when ABS comes on its a wheel speed sensor messing up.

It doesn't seem to be coming on anymore. It was before the caliper replacement last week. I just tested it yesterday and the lights don't seem to be coming on.

I had this happen on an F-150...years ago. After replacing the brake hose, I cut the old one open and found the inside lining was loose....acting like a check valve on the caliper.

If its pulling hard to the left (& you already replaced the right front brake caliper), I'd try replacing the RIGHT FRONT brake hose next. It may be collapsed? If so, that will cause the left caliper to react faster than the right side, causing it to pull hard left when initially applying the brakes.
