Hi all,

so, I did stumble over a RRC brake pipe kit from Automec on sale when looking for something else a week ago. The price was really good, lamded including VAT and customs less than a hundred bucks instead of 200+ pounds as sold by Automec. It was advertised as LHD RRC, and the MYs were correct as well.

I should have checked the part on Automec's site, because it very clearly is a) RHD, b) only for the rear and c) imperial and not metric.

I'll propbly put it on eBay, returning to the UK supplier is a pain with customs and all, plus I might get more than I paid for (unless someone here has a use for it, if so ping me!). Looking at it, well, I have to say, building those pipes yourself seems like a doable task actually. Anyone already did this, building brake pipes from scratch? Tools are cheaper than one of the two sets needed, material isn't expensive neither. Plus, mine has all those things for the pneumatic brakes still.in placr, custom building seems like a reasonable thing here.

Reason I am asking, she still has the original steel pipes. Metric ones, no idea why Automec is only selling a metric set for MY 84 onwards, but then part suppliers are not always on top of specs for specific model years.

As I am almost sure to upgrade the cylinder heads next year, requiring a dyno test and TÜV due to the power increase and subsequently requiring a brake upgrade (required or not, more powerfull brakes for a more powerfull car are logical).

Doing that and replacing the brake pipes sounds like a fun thing for next winter or so! 🫣

To make it short, how difficult is it to build and fit those brake pipes, assumong the use of proper tools?

Greetings,

Florian
 
Don't know what the classc pipe routing is like, but I did the rear pipes on both my P38's.

Roll of copper-nickel pipe, fittings & flaring tool. Hardest part was feeding the L-R pipe over the rear crossmember. The P38 have a joint behind the right wheel-arch liner so that end was easy.

I did vacuum the fluid from the old pipes first, to avoid spilling much on my driveway.

This is the LRCAT view of the rear pipes:

Use CUNIC for the pipes, it's pretty cheap and easy to make the pipes up, I have had to replace the rear pipes on my P38.
 
Thanks folks, so I'll get a flanging tool, some copper-nickel tubing and all necessary fittings. A man needs something to do during the next winter! By the current rate, I'll do the cylinder heads myself next year!
