Hi all. Was out driving my 2005 z this afternoon. Lovely sunny day. Stopped for a bit. Got back behind the wheel to find that my brake pedal travelled virtually to the floor. Pumped the pedal a couple of times and all seemed fine again so started the drive home, gingerly. After a couple of minutes it seemed as though I was driving with the handbrake on and the dSC warning light came on. Any ideas?
