total brake failure

[doctord]

Enjoying an early morning blast along quiet roads , after some heavy braking i thought the brake pedal felt strange. I assumed it was perhaps the ABS briefly cutting in. After next burst of overtaking , my brake pedal started sinking to the floor.
I decided to pull over and almost ran into a ditch as the pedal hit the bulkhead with very little braking left. A puddle of brake fluid was developing in front of a rear tire.
The Porsche dealership explained that my brake pipe had corroded [2003 model] as a result of mud being trapped between the undertray and the body. I have no idea how it got there. So much for my full Porsche dealer service history.
Perhaps this is a check that needs done yearly at the same time as extracting the leaves from the radiator/air con air intakes!
