Jeep pulling to the left

[braxton]

So I recently got a 1999 tj sahara and my front 2 callipers seized and so I replaced them and used the old rotors and pads which were in good condition and the pads looked of before I put them back on and recently it’s been pulling to the left when I brake but only when I brake so I tried to bleed the front left caliper and it fixed it for a bit and then it came back to I bled both front brakes and it went away and came back again also my brake pedal is really hard like I’m barley pushing the pedal in and it’s braking I really need help because I can’t figure it out now

 

[rasband]

When you replaced the calipers, what all did you do? Did you use new copper crush washers with the banjo bolts? Has anything else changed?

How old are the brake soft lines? How thoroughly did you flush the brake fluid? Don't discount tire pressure or alignment either.

That isn't really how it works. If you had enough pedal throw, you could have one caliper full of fluid and the other full of air and that still won't cause a pull because both front calipers are common to each other hydraulically so there can never be a pressure differential side to side.

Not to mention, if there were a way to get one side to brake differently based on air or bleeding, the side that is pulling would be the good side, not the side that needs bled.

I'm going to venture that you need someone who knows brakes to take a look at it.

What would the symptom be for bad flex hoses?

How thoroughly did you flush the brake fluid?

And the symptom of never or poorly flushed brake fluid is?

Don't discount tire pressure or alignment either.

If those cause this particular issue, who is changing the alignment and tire pressure when he isn't looking?

I don’t know what you want me to say because that is what happened I bled the left one and it fixed it for a bit then I bled both and it fixed it for a bit again so idk

I didn’t flush the fluid but the soft lines are essentially brand new

Can you clarify this statement? Are you saying you replaced them at the same time or recently?
