Question on brake shimmy after high speed stop

[Orca]

Took the L out after the 90mm mass air, oil breather cap, and JDM J49/69 upgrade. After running it upwards of 120 I hit the brakes pretty hard and had the abs activate some. When I reached a stop I had a strong smell and smoke coming from front pads. Now I have a slight shimmy when stopping normally from 50+mph. I tend to think all I did was glaze the original pads (16K on truck) but am wondering how easy it is to warp these rotors. Mine do have small heat checking (small hairline 1/8" lines) but I still don't want to believe I warped them with this one stop. Is this the reason others are going to ceramic pads from NAPA? I hardly ever uses these brakes to their full potential, so they might have been dirty with old dust or something. Any ideas?? What is the part number for these NAPA ceramic pads? Do you also do the rears too? Thanks

You can warp rotors in one stop, especially if they were cold and then you knocked the crapola out of them. There's not a lot of rotor for the weight of the truck, and shimmy tells me you warped 'em. Might try removing them and having them turned, but I'm guessing you probably need to replace 'em. Good news is that they're not HORRIBLY expensive, I'm trying to remember, something like $150 for both fronts. Still more expensive than not warping them in the first place.

Next time: bed in your brakes properly. Baer has instructions on their web page. And when you get the hankerin' to go a buck-twenny and then hammer the brakes, warm 'em up first with a few calmer stops, that way you won't make your rotors go from ambient to 500 degrees in 10 seconds. (Hmmm, could that be why they warped?) This is why they do a warmup lap before road racing.
