HEAVY SMOKE... Seized brake caliper?

Hey fellas, I was driving home from barns and noble picking up the latest 4x4 mags and something felt wrong with the jeep. First, when coasting to a light, it seemed as though I wasn't rolling as far as though I was really aired down even though I'm not. Then I noticed it was harder to start off in first gear, I had to slip the clutch some more and throttle more. The my steering wheel started to pull to the left. Not hard but if I let it go it would move in the counter-clockwise direction. Finally when I smelled really pungent smoke I pulled over to see what was up. At this time I noticed smoke coming from the front of the vehicle. After limping 1 mile home in 1st gear my thought are that my front driver side caliper hit the fan. I don't know much about brakes, but I'm pretty good with a wrench. My 4.0L has 115k miles on it, not sure when if ever the PO replaced brake parts, so it could all be original. Does it sound like the front driver caliper seized to you? If so what are my options, rebuilding it or completely replacing? What kind of money am I looking at? Thanks, just glad it was the beginning of an oil fire.

Had trouble with my drivers side brakes as well. It ended up not being the calier it was just the pins it slides on. Mine did not result in any smoke though. It just got real hot, it had trouble geting up to highway speeds and would not stay staight under braking.

Just something else to check.

What did you end up doing to fix it? I haven't had a chance to pull the wheel off and take a look at it. Will do that later tonight. What should I look for? If it were the pins would it be obvious?

Advanced Auto - 25 bucks! 15 mins to replace.

If it is the bolts, pull them out and give them a good helping of grease, and take a bit of sand paper to the part of the caliper that they slide into. 10 minute jobber!

Good luck

Thats exactly what I did. They lock up because they dry out. Get the grease that is made to put on the back of the pads to prevent brake noise. It will not melt like other greases will. Clean up any corrosion. I ended up replacing the pins the next time I did my brakes.

If this is the problem you will be able to tell when you get the caliper off. The pins should slide in the caliper very easily.

this an after thought. but if you had smoke coming from you brakes, you might want to bleed them (if you don't replace the capiler) just incase the heat from the brakes didn't boil your brake fluid. have fun and good luck

Old or damaged brake hose can cause it too

Smoking one means you likely cooked the bearing grease also

Go ahead and change your pads while your at at, at least do some light sanding on the one you cooked. It is likely it looks like a sheet of glass now.

just replaced my passenger side caliper yesterday. i've been told by several mechanics to change out the flexible brake hose also. has something to do with breakdown inside the hose and not having enough pressure to free the caliper. hope you didn't bake the grease in the wheel bearing pack, cause those things are pricy. good luck
