997 brake fluid leak
Discussion

This reads like a hard line break rather than the flexi that goes to the wheel, and IIRC, the hard lines run beside the gearbox then under the nearside floor.
You can't see them without removing the undertrays, and that might actually show up more horrors if the line's split, as more might be right behind it.
It's not necessarily a difficult job, but it is very time consuming and fiddly.

If it is like the 996 there is an ally joining block in that region. There are two rigid pipes that come from under the n/s front wheel arch to the block. From the block one rigid pipe goes to the n/s rear wheel. The final rigid pipe goes over the transmission to the o/s rear wheel. If it is this last pipe then its a big job. One of the other 3 then I’d estimate 2 hours ish.
I’ve changed all on my 996 apart from the transmission pipe which GCR did during a clutch change. None are particularly difficult.

Thanks Stig. Hopefully its not all rotten.This reads like a hard line break rather than the flexi that goes to the wheel, and IIRC, the hard lines run beside the gearbox then under the nearside floor.

What was the diagnosis?
Yes it was a corroded hard line under the N/R floor, just on a clasp and a bit of other decay further down. Not the horror show I was expecting. I had the choice of OEM part or they would make a pipe up. Chose the latter. I totally forgot that in 2019 I had pipes at the front replaced! Going to get rubber hose replaced to coolant pipe as a precaution and also there are two metal bars that support the rear subframe that looked toast to me but i was assured that they could easily be cleaned up. A few taps and the surface rust flaked off to reveal thick solid metal. So all in all it was not viewed as too big a job really. Advised to just keep on top of things and work my way round, getting other stuff done from time to time. Cheers.Feel for your pain…I’ve been banging on for years about the poor quality materials Porsche choose to use for some parts. Brake pipes,fluid lines , radiators, condensers and almost all of the underfixing fasteners corrode rapidly requiring (expensive) replacements. I’ve run a 2000 model PoloGti alongside my 4 porsches since1999 . The polo has same drivers ,travels the same roads and distances and has never need replacement of these mentioned parts through corrosion. All my porsches have need some or all of these parts replace due to corrosion🤨….it’s about time we all complained a bit more and maybe those in charge would stop penny pinching on materials…the 911 is a brilliant car , drives like nothing else….but does have sh..e parts that spoil the experience for many..rant over.
