HELP ASAP braking problem!!!!

So a light goes red i push on the brakes only to change lanes and pucker. I would have hit someone if they would have been next to me. The jeep pulls hard to the left when hitting the brakes only. It does not pull when going backwards and hitting the brakes. The e-brake does not make it pull either. It was fine five minutes before this.


I am not leaking any fluids. Nothing seems to be broken. Tires seems great. They loog almost new. Has plenty of brake fluid.



Please any ideas at all. I was going to do a full tune up this week to get it ready for a smokey mountain trip next weekend. So this issue needs to be fixed ASAP.

This is a video of it in action. the last time i hit the brakes i let the wheel go to show you how extreme it is.


PLEASE dont say how i should not try to record while driving. Yes i know its wrong. I was the only one on the road and i could see for a very long way. So please either help with the issue or be kind and keep the comments to yourself.

Your caliper is stuck on the one side it's not pulling to. That's the problem.

Also check the brake line and make sure it's not shot.

I would check your rear drum brakes if the front ones don't show any problems. E-brake is tied in but some of the mechanics of the brake is circumvented. don't take them apart unless you need to though. reassembly requires some special tools.

with the front axle in the air the front right rim has play up and down. It is tight left to right.

By play i mean its enough to feel it with ease and way more then the left. left side felt like no play at all. right side has play.

It's the caliper. It will not do it when it's cooled off. Take it for a ride heat it up. Then it will start again. Then check it.

If you can rock the tire back and forth with your hands at the 12 and 6 positions with the tire in the air, you probably have a shot unitbearing.

There should be zero play.

Yes i would say 100% the unitbearing is bad. It has been squeaking at speeds since my last off road trip.

I will put my tire back on and head to the auto store. wish me luck guys. Ill be back on in an hour 1/2 so please if you come up with anything else let me know.

I just put a new front left caliper on the jeep and made sure to get all the air out of the lines. Still the jeep pulls hard to the left when stopping.

Sounds to me you have a nice new caliper on the side that was functioning normally

I do agree. It pulled to the passenger side when my drivers seized.

The other side should not be working and therefore it pulls opposite.

You are correct. The OP says it pulled left and he changed the drivers side which was the wrong one to change. He should have changed the passenger. All he has to do is just keep driving when it does it and smoke will show him the correct side, no question!

My bad. It was the right side i changed. I changed to a new caliper and pads. It still pulled to the left (drivers). Even after changing the caliper and pads it still pulled to the left when stopping.

Well due to my trip to the Smokies next weekend i said i might as well change the hole system.

New pads, new rotors, new calipers, and i fully flushed and changed the brake fluid.


Jeep stops better then ever. Thanks for the help guys.
