[Supras] [SOGI-TECH] brakes smoking??

[Supraman]

Take a look at the calipers.
Mine locked in the driver's side front and made a real decent smoke show. 
Smells funky, too.
What had happened was the slider got stuck; the caliper itself got rusty and 
the slide, wouldn't.
I had to replace that one, it was just too far gone to resurrect.
However, on the rest of them, I *GENTLY!!* removed the slide and the boot, 
and then took a Dremel tool with a sanding cylinder on it and sanded them 
down smooth, and then finished with emery cloth followed by 400-600 grit 
sandpaper.
I also removed the pits from the slide with 600 paper followed by 1000 for 
smoothness. Then I used either anti-seize or hi-temp grease, and then 
reinstalled the boot and the slide. If you rip the boot it is not a 
catastrophe, you can get it in a kit, but better not to rip it. It will 
cause the problem all over again, only accelerated.

Good luck. This is an easy fix; I hope this is your problem!
