driver side front brake locked up

i used the search, theres an ish load, mostly wj's with simalar post but i dont know the simalarity's between the 2.

k so it locked up, jus the one, i could smell them on the short drive home today and checked it when i got home. seems to me it would be the caliper but i dont know if there could be something else like a combonation valve or something that would cause it. not familiar with brakes on these. mostly jus my old chevy's.

can i jus do a typical bench bleed or the ol' pump the peddle bleed or do i need the abs tool to check for air in the line. i did the pads a cpl days ago when i found them falling apart after breaking a cv. but ive done pads before without issue and i didnt do anything differant this time.

any info appreciated!

its probably internal in the caliper, once it locks up once, its going to happen again.

Had one lock up on me recently, just replaced it, they are really cheap

I dont have abs, its pretty hard to bleed abs systems properly I guess without the right tools.

Bleeding it isn't going to do anything. If you had air in the line you would have a bad brake pedal it would be muahy and your jeep would not stop very well unless your pads are somehow slammed up against the rotor the brakes would only be so hot because of a stuck caliper maybe when you did the pads you pushed the piston in past where it wanted to go, hit a ring of junk in the piston and now its causing it not to release

Yea, I wasn't expecting bleeding it to fix it really. Jus wanted to make sure before I got started.

So far seems pretty unanimous on the caliper, myself included.

You don't need to bleed the abs system unless you opened it up. When you replace your caliper you bleed it the way you would anything else, you can gravity bleed it, vaccum bleed it, or do it with the pedal.

Glad you got it all fixed! Even more glad to hear you have a kid who shows interest in what you do and that you actually took the time to spend with her and show her what your doing. I bet it feels a lot better driving now! How does the pedal feel? Any brake pulse? I was curious if you warped the rotor from the heat

Yea all is well. It's less then half a mile from work to home so no warpedge. And she came out to ask if she could watch tv and quickly got distracted then we went on a test drive and she loved that since I was kinda driving like fool.....slamming on the brakes and all. Pedal feels kinda wierd to me but I'm sure its Jus cuz it feels like new! Better then ever!

When your doing brakes its always best to do it in pairs. I would never just change one caliper unless I could not afford it and I would never just change one rotor and one set of pads
