Replacing solid brake lines with flexible hoses

I've finally decided to get around to making this change. The parts have arrived from Redline. So are there any tips and tricks or even gotchas that I need to be aware of? I'll also be changing the existing hose from chassis to tube as well.

Is this for the whole car or just for the DeDion tube?

I asked the factory if they knew of any disadvantages of flexible hoses for road cars. They didn't, and didn't mention any hints or precautions for changing to them.

I did this over the winter, I used the Caterham supplied ones, I found that the hoses were a bit tight on length for easy routing, they were routed behind the watts-link bracket, protected with some rubber hose and secured with a tie-wrap.  Have a look at -

Try fitted mine, not happy with any route around the radius arm mount, found them too tight and liable to chafe., took them off again til another day. Think using a piece of old hose as a sleeve to protect them is right way to go.

I was about to describe what I did only to discover that michaelf  has already posted a link to my earlier thread!  That saved me some searching, so thanks.

Chris, if your car doesn't have Watts links, I guess the routing problem doesn't really arise as your radius arm is lower.

I got parts from Demontweeks ages ago and made them up myself - fit perfectly.

I guess its another case of caterham ignoring customer feedback and ploughing on with how theyve always done it ( the k dry sump kit always had shortages of essential bits despite feedback!)

My suggestion to Tazio was to get a new long hose made up using fittings from the short hose. Then shorten the original long hose to make a new short hose IYSWIM.

Thanks guys. No watts-link on mine just radius arms mounted in lower position. I'll see how it goes with routing and consider making a longer hose as suggested.

Look at the order things are done in the assembly guide - some bits rotate and other bits don't.

My old DeDion tube had the pipes just tie-wrapped in place. The current DeDion is drilled to pop rivet the pipes/hoses in place.

So I have a 2002 SV with solid brake pipes tie wrapped to the De Dion (self build)-this always looked crude but seems to work- what, if anything, is the advantage to changing to flexible hoses?
