You have to remove the boot trim. I discovered my crack because you have to take off the trim to check the brake fluid which is what I was doing. OPE just reported another R8 at his dealership with the exact same problem. That makes me [KOPPO] DANKO and JBK plus OPE with the EXACT same problem. Clearly there is a problem and if we can get more members to check their brake fluid and check for these cracks we might be able to seek some recourse from AUDI. My dealer confirmed a drop in value due to my incedent between $15 - 18,000!
