Okay, guys. I know several of you, as am I, are using Wilwood brake assemblies on your cars. Earlier this week, while replacing the front pads, I decided to remove the dust covers for a quick visual (peace of mind) inspection. Even though I had (continue to have) zero slop in my assembly, I simply wanted a peak. The photos below are what I found. :ack: That sparkly stuff adhering to the grease on the cotter pin, the castle nut and the end of the spindle is aluminum shavings. :svengo: Those are also aluminum shavings in the dust caps, and were once part of the dust caps. It seems the cotter pins (both sides) have been rubbing against the inside of the dust covers since installation. Luckily, there was no damage other than the dust covers. However, bearings are being replaced for, again, peace of mind. My words of advice?......go back, remove your dust covers and check your assembly for cotter pin-to-dust cover interference…..just in case.
