Dr. Diff 11.5" front brakes showed up tonight

That rough surface will burnish in when you make several hard stops from about 60 down to 25 and rinse and repeat a few times. This burnishes the rotors and the pads finding everything a "home" so to speak and seating everything in together.

Nice car and cool brake kit. I am working on refurbishing the Kelsey Hayes 4 piston setup I have for Vixen now. With those and some 10" rear drums, she should have whoa like she has go now.
