Brake caliper drag, intense heat and tire worry...

I recently experienced a front (disk brake) caliper drag situation. It unknowingly became so bad the front-end began shuddering and prompted me to pull over for a quick look-see at what the heck was going on. The right front wheel was smoking! The rim and tire were so dang hot I could NOT touch either for more than a split second!

Needless to say I called in a tow to deliver my Jeep to my home for inspection and repair.

After some thorough research and some discussion with MrBlaine (and previous experience with the same 2000 Wrangler Jeep and same dragging situation, ten years ago) I determined it must be some particulates in the brake fluid settling in and interfering with the caliper retracting.

As a result of the dragging and intense heat generated, I will replace both wheel hub bearings (Timken), the rotors, the calipers, and pads (Black Magic Brakes components) and both right and left (flexible) hydraulic fluid lines (Doorman via Rock Auto). I will also be flushing the holy-heck out of all the brake lines to clear out any bad fluid or any potential minuscule debris that may be lurking in the system. I certainly don't want to repeat this upsetting and expensive situation.

While awaiting ordered components, my question is since the tire got so hot I simply couldn't bear to touch it, could there be damage to it? Upon visual inspection, it appears fine and hasn't lost any pressure or anything obvious like that. I'm particularly concerned as these are new tires (only a month old) and would hate to ruin that one.

Anyway, your thoughts on the tire matter would be appreciated.

Yes, a tire overheated by a dragging brake can be damaged and become unsafe. If you're think this may be applicable in your case, it might be a good idea to talk to the shop where you got your tires to see if they can do an inspection or otherwise address your concern.

jimbolina ... I just started a thread about my 2000 Wrangler pulling to right when braking after a brake job and also it smelling like something is burning or getting hot when I get out. Did you're car pull to either side when hitting the brakes?
