A few 'hard brake line' questions re turbo

[ukmastiff]

Not hard questions, just re hard brake lines []

Is Copper brake line O.K / good for replacing my brake lines , is it definately 11mm nuts I need on an early 944 turbo
and do I buy a specific diameter of brake line.

It appears investing in a set of Flare spanners might also be a good idea ?

Regards Mas

Thanks Chris. I may have someone who can help me this week so if I do need these nuts I'd like to go out and get them ASAP

I dont actually know they will fail but they were an advisory on last MOT and its due on Thursday []

I'd like to change them anyway obviously.

Regards

I've had copper replacement sections fitted to both of the daily drivers I've owned over the last 20 years. I keep these cars for 10 years or so and in that time nothing untoward occurred as a result of the changes. The copper seems to last much longer than steel.

Copper kits normally come with new clips & should be clipped closer together than steel. Lots don't bother & have no problems. I've installed probably 100's of feet over the years & never had a problem. Also it is easy to get a reel of 3/16 & some fittings & make your own. Also used with brass fittings you'll never have corrosion issues again.

I prefer to use kunifer for brake lines. If you go to a motor factor ie dingbro or tms and ask for a roll of kunifer ( about £13 ) and a pack of 11mm male ends ( £ 5 for 50) then all you need is a flair tool. I use a sykes picavant tool which will csot you about £140 ish.

there you go all you need now is a bit of time and patience.

There's a Silverline flaring tool on EBay for £8.99[8|] Here

 

[colin944]

There are cheaper tools available but they tend not to be very good.

Are you speaking from experience?

I am unfamiliar with the Silverline tool, but this appears to be a similar setup to the Snap-on version, which I have used for many years to good effect.

I have other Silverline kit that seems to be solid and works well.

For the money, it's worth a punt I would have thought. [8|]

The silverline tool looks quite similar to the Clarkes kit that machine mart sell, main difference with the later is it also includes a pipe cutting tool which is very useful for creating straight edged non-squashed ends for flaring.

what dia is the kunifer pipe for a 944t?

any prefered material for the 11mm ends in the alloy calipers?

thanks

 

[chrisg]

I think the kunifer pipe is 3/16" diameter - there is a far as I'm aware only one diameter of kunifer pipe available.

The end fitments that go into the caliper at one end and flex hose at the other are coated steel with an 11mm nut.

If it helps I can send you a section of old brake line from the rear for comparison purposes ?

Yours

Chris

Yes it is worth a punt . I would suggest that it would be fine for copper but not for Kunifer. Kunifer is a much harder and more resilient material than copper.It is harder to bend and much harder to flair than copper.This means that your lines will be stronger and your ends and joints will also be stronger. The problem I have encountered with the silver line type tool is that the pipe will slip through the clamp and score it quite badly and also stop you from getting a good flair. However that is all with Kunifer and copper would be fine.

Just a note all Porsche fittings are M10 x 1mm the 11mm is the hex size (or it maybe 12mm I can;t remember)

11mm standard size fittings.You get a few different size fittings but if you tell your factor that they are 11mm he'll give you the right ones.

If using that silverline type tool make sur the washers on the clamps do not get caught between the two sections as this will allow the pipe to slip when flaring.
