I had new stainless steel flexible hoses fitted when I had new discs and pads fitted with the calipers overhauled. From what I can remember I think they were Goodridge and they werent that expensive. I cant be more specific on cost as it was all factored in on the invoice when the work was done.

No need to drop the transaxel to replace the rear line. It's a fiddly job but perfectly possible without dropping the transaxel. And in anycase you could route the line under the transaxel and if you ever needed to drop it it is a pretty cheap and easy thing to replace that short section of line once the transaxel is off.

Yes there are Porsche brake lines that are pre bent to the right shape and length to be an exact fit.
More and more of our cars are now having corrosion problems with these pipes as they approach 20 years old. Replacement with genuine parts is not cheap so a lot of people use flexible piping instead. I'm not suggesting this is an inadequate solution as many people do it with no problem, but on my own car I wanted to use parts that I know will last another 20 years [

Not after they have been through the post or you have been under the car wrestling with then like they are an 8ft python [
]Get a flaring tool, you could use mine but I cant remember who borrowed it[
]The pipe work is available in different qualities so it could be possible to get materials that are better than standard.

Porsche parts aren't the only ones that last for a long time.
In fact, I believe that Porsche use mild steel for their OE brake lines, as required by US regulations. Which rusts, which is why it needs changing.
Aftermarket brake pipe (of which I have a large roll in my basement) is 'cunifer' which is some soft copper alloy, which won't rust, and hence will last a lot longer.
Don't shy away from aftermarket bits just because they weren't made in (or packaged in, or ordered from) Stuttgart.

I had a local garage replace the Brake Lines with Copper which they made up - cost about £200 for the fitting and bleeding.
The Fuel Lines are similar, I used "rubber" fuel hose from a Motor factors with double hose Clips(not Jubilee's), and did 'em mtyself for peanuts.
All routed over the transaxle.
Its not a nice job though - if you're used to sitting at a desk for a living[]

I'm very suspicious of flexi hose replacements for the fuel lines. The lines are fully exposed to all the rubbish kicked up off the road. I'm sure they are probably fine and will last for many years but if I were you i'd begin a regime of regular visual inspections to look for any nics int he rubber or signs of chemical or ozone attack.
For braided hoses look for freying braid. As vibration is transmitted along the hose the strands of the braid rub together and eventually start to frey, especiall in areas where they are bent around a tight radius. Again, i'm not saying they are not fit for purpose or unsafe, just that they are not as robust and maintenance free as hard lines and need an eye keeping on them. I certainly can't imagine them being able to last 20yrs like my fuel lines did.

Scott,
I used fuel hose, and special clips. After 2 years they remain perfect.
Look at your lawnmower or a motorbike they all use flexi hose. (albiet without pressure)
Fuel hose is not rocket science, and I dont subscribe to all the guff we hear from companies who want to sell us cayman's for 50 grand[][][] or charge us 400 quid for two pipes.

I am not sure why the reluctance to use braided hoses for fuel? Why ever not? Far easier to install provided the correct fittings are used.
Modern braided fuel hoses are fine. After all a recommended update is braided hoses for the brake lines to the calipers which are in a far more exposed position, flap around madly subjected to greater heat/cold cycles and much higher pressures.

Actually that's another area for us to debate [8|]
There is a school of thought that braided brake lines should not be used on a road car because you cannot inspect the rubber hose itself hidden behind the braiding. These hoses are fine on a race car where they are replaced every year and inspected after every outing, but a road car may not get the same loving care, and I wouldn't wish brake problems upon any one of us []

This thread has jogged a memory now. I'm sure i've read or heard about people having problems with the rear braided brake hoses. These obviously bridge over the rear torsion bar tube and onto the trailing arms so flex with the rear suspension. As a result these are bound to see more flexing than the front brake hoses.
Does it sound familiar to anyone else?

Hi Lee,
Promax are fitting new brake lines for me as we speak, cost for all three rear ones and the two in the front wheel arch that need doing on my 944 2.7 are £231.81 Inc vat plus 2-3 hours labour, these are genuine preformed brake lines. I am also having a complete set of fuel lines, Wilwood brake kit and KW suspension fitted at the same time.
Hope this helps.
