I recently put my summer wheels back on my car and pulled the brake pad out to see what kind it was. When I bought my Z last August, the previous owner told me he had recently installed Hawk pads, but he didn't know what pad it was... These pads bite harder than the HPS pads I had in my previous Base Z. I thought they might be HP+, but now I think they're Performance Ceramic.

 

Hawk PC504 are Performance Ceramic's.

 

thanks for the info! I thought they were once I saw the code, but I couldn't find any info that would verify this. Can you tell me where you found the code, just so I can have it for future reference?

It looks like that is printed on a shim, not the pad. It's possible the shim was re-used on a different pad.?
