Hi guys, I have a C5 RS6. Unfortunately I grazed a concrete barrier by hydroplaning on unexpected water build up. Fortunately road rash to both left wheels (uugghhh- BBS). However my brake pedal goes almost all way the to floorboard. Car stops but something is obviously wrong. Checked brake fluid and it's ok. No visible leaks. Any ideas???
