Speaking of greasy, I noticed the steering rack, tie rod end, lets grease exit close to the rotor on my Wilwood brakes. I had a clump of grease on the caliper, next to the rotor.
It did not look like the rotor had picked up any grease and contaminated the pads, but I pulled it all down to confirm and washed everything down with brake cleaner.
I will really have to watch the grease, while lubing the chassis. I hope this saves someone an issue.
