Do these rotors look normal?

    I have a shimmy in the steering wheel when braking at speeds over 50 mph. I was rotating the tires and noticed the color pattern on the rotors. What do you guys think? These are Powerstops that have been on for about 6 years. My next step to look for warpage is to put the factory rotors back on.

    You have a hot spot. Something on your pad maybe causing irregular wear.

    I have one that i borrowed from a coworker. What is the best way to check runout since these are slotted and drilled? Also, what is the "out of limits" that indicate it should be replaced?

    Or could I use a digital micrometer?

    How much meat is on the pads?
    How does the back side of the rotors look?

    You can still check runout. Just keep the dial indicator out of the drilled holes. .002 is the limits.

    I would say about half of the pad is left. I will look at the back side today because I was curious as well.

    See if there are wear indicator tabs on your pads that line up with the stripe on your rotor. If they're bent a bit maybe they're dragging when you apply brakes.

    First I thought contaminant but seeing the same pattern on each side points to pads.

    The wear indicators aren't anywhere close to the rotor. On the pads that I have, the indicator is on the edge of the pad but the hot areas appear to be in the middle of the rotor?

    Not trying to be negative, but I wouldn’t even waste my time to check that shit. Throw it all in the trash and start over with some new rotors and pads..

    Like Jeremy suggested, you have 6 years on those rotors. Pretty good in my opinion. I would probably just replace rotors and pads, rebuild calipers as needed.

    At some point, maybe you had the front rotors pretty hot from something. At least both sides are showing signs of heat/wear evenly.

    Something else to check out when doing brakes. Check run out on the bearing hub when the rotor is off. This is 99.9% probably not your issue, but in the future if there is one side of a vehicles brake system giving you problems, check the bearing hub assembly.

    Make sure all the brake “rub” surfaces are clean and slightly lubed with a light coating of grease. Check the pins too. Clean and lube with grease. The pads my not be releasing fully and dragging after the brakes are released. Hope this helps.

    So after digging in a little, this is the Z23 kit and it is 3 years old this week. Since I am running 34's now, should I replace them with the Z36 kit?
