anyone have an opinion on braided or aftermarket brake lines for the 964? my brakes are due to go back on this weekend/next week and i was considering fitting some braided or re-enforced lines, but wondered whether there was anything I havent considered?

i have the standard C2 brakes (smaller rear caliper) and the change is literally because I couldnt split the hose from the tube on the caliper. I will be replacing the tube from the caliper to the hose (OEM part from OPC) and the hose from that to the wheel arch...

I have looked at a few types and there seems to be either stainless, alu, or plated nuts available. Personally my thoughts are fully stainless is best, but not sure if i would be better to go with alu to prevent the welding ive experienced this time!..
 
Well I've just replaced mine with Goodridge braided ones. A lot of feedback I got before doing this was that they won't be any better than the Porsche originals but they are certainly cheaper (about £50 for a set).

Stuff to watch out for - be prepared to have to replace the hard brake lines that connect to the inlets of the hoses (i.e. the car side of the bulkheads). All but one of mine were completely siezed. If you can flare copper/nickel brake pipe and make your own you will save a lot of money because the ready made ones from Porsche cost on average £50 each.

Like yourself I had to change the short pipes from the hoses to the calipers (I've just put 4 pots on the rear). They weren't too bad at about a tenner each.
 
cheers steve.. i just got some prices for those tubes this afternoon and they were £10 for one side and £15 for the other.. I have flaring/bending tools and tube, so wil make my own, but might try to get hold of some stainless tube/fittings for that section too.

i was looking at goodrich ones and think ill probably go that way with it

The pipes Porsche now supply for the rear calipers (caliper to hose) are much improved over the old design due to the thick coating that stops the pipe seizing in the nut. The nuts look to be made of brass (I'm no expert) which I guess is better for the alloy of the caliper than something as hard as SS.

BTW the rear ones (which I thought you meant in your first post) are exactly the same (and therefore the same price) but the fronts are different on each side.
 
thanks steve..
prices I got from OPC yesterday are

NSF Brake Line: 96435558103 £10.13 +VAT
OSF Brake Line: 96435558204 £15.12 +VAT
Rear Brake Line: 96435519100 £8.55 each +VAT

and i think you're right, SS would be a bit hard on the caliper body.
i will get the OPC parts for the "outboard" tubes but will probably make my own ones for the "inboard" section if I can't get the hoses off without damaging them

will post the results once I get around to it!

I think you are being a little over-cautious as regards stainless steel - after all the bleed nipples and tube nuts on the "stock" tubes are zinc plated mild steel so stainless is much better in terms of corrosion resistance. Your choice of course. [8|]

I took a look at mine tonight and agree, they are zinc pasifated or yellow chromate steel.. stainless might be the way to go; im litterally thinking of corrosion resistance and making the job easier if I have to do it again..

I spoke to GCR this morning (my local specialist) regarding the lines and they use 90/10 cupro-nickel for all of their brake lines and make them all up in house, so I might just scratch buying from OPC and spend the £20 on s/s end fittings and new bleed nipples instead

Does anyone know what size the tube and the end fittings are?..

ben
 
Of course you're both right, they're not brass at all (told you I wasn't an expert). So I can see why SS shouldn't be a problem. They're M10x1 fittings and the pipe is standard 3/16 inch OD stuff.
