Hard braking pull

[avidtest]

Has anyone experienced a hard pull to the front driver's side under hard braking, particularly if your truck has a lift? Ineos is suggesting this is par for the course based on suspension design, especially if the vehicle has a lift kit. It's pretty scary, especially the 1st time when not expecting it.

Straight line braking on dry pavement? Hard braking as in ABS activation?

I’ve been pretty easy on my brakes so far but I’m curious now

Straight line on pavement. Ineos is replacing the front calipers and pads. Left front had heavy wear compared to the others. They're not sure of the cause currently.

I have absolutely have this. Happens after a long hour or two drive. Hard emergency braking makes it pull hard. So much that it would change lanes quickly. You can resolve it by braking very hard a few times. It will come back next time you take a long road trip. Ineos says everything is fine and they couldn't duplicate. They did bleed my brakes since they had replaced a brake line early on. They thought may e there was some residual air. I thought it helped at first but the condition came back again.

Super sketchy and not even remotely safe. Interested if anyone else finds this issue.

Oh and just a note, it happened before and after lifting.

Maybe bad caliper with sticky piston(s). It would be good to see/test that caliper.

Mine does this under hard braking but its controllable. I also noticed it on both of the loaners I had when in for service. Those are bone stock and mine is lifted.

There were two instances of hard braking that caused a large red light to come on under the windshield,
but no major issues.
The car has never been lifted and I received it in October '24.

So there are 3 cases, all in the USA? I have not had this but also no long travels.
Does the body roll when this occurs?
Have anyone stopped and checked if there is lots of heat in the front brakes? Don't touch the caliper, just feel the radiation or touch the wheel.

It's not air in the system. That will cause soft pedal and/or long pedal travel.

Dealer checked temps. Ineos said all were good.

Truck is controllable if you're prepared for it.

Sadly many will never notice this defect if they dont hammer the brakes at speed.

The body rolls a bit like you're changing lanes. It exacerbates the already squirrely nature of the Grenadier at higher speeds.

I will have them tear into it more when I take it in for the door handle recall.
