fired up my 997GTS after a 2 month hibernation and got to the end of the road and brake pedal felt mushy, then went all the way to floor and brake fluid warning light came on and no brakes! Fluid now dripping from the middle of the undertray so look like a brake pipe has gone. It's off to OPC Edinburgh tomorrow but I find it difficult to understand how a brake pipe could fail on a 7 year old car that has full OPC history service. Are underside brake pipes a known issue?
