I have a 07 RR with 5600 miles. It has a Brembo R1 master cylinder and stock calipers and lines. This bike is 100% track and not street legal so I can really only trouble shoot it at the track. I noticed the past couple times taking it up and down the driveway the left front caliper is not releasing. The right side is fine and functions perfectly. Any recomendations what I should be looking into?
