Rear brake calipers are fitted with the bleed nipple upper most.

If fitted with the nipple lower down (which is to say swap them from left to right) then bleeding the brakes will be difficult as the caliper has to be removed and turned so the nipple is upper most.

The hand brake cable will now approach the caliper from below.

The brake pipe is fitted and is routed down the drivers side of the cockpit

Continues along the outside of the engine bay

And then enters through a grommet into the rear of the engine bay.

Up the rear chassis strut

Across the read chassis member to terminate into a three way union where the flexi pipes connect and run out to each brake caliper.

Note the brake pipe is about 20cm short, it is not centrally mounted. It works fine, just not aesthetically pleasing. I'll have a longer pipe delivered if there is a next time.

Flexi pipes connected and run out to the brake calipers taking care to avoid issues with suspension movement etc.

Note that I have covered the 3/16" brake pipe in a split plastic sleeve for most of it's length.

I wanted to protect the soft copper from all the work that will be going on with various bits put on, taken off, adjusted, put back again. Also protects the pipe when radiusing around corners. It also makes it easier to bend the pipe by hand with a lower risk of kinking. Once inside the engine bay, 3/16" clips are used to fix the pipe in place. The flexi pipes are held in place with tie wraps. Not terribly elegant but functional.
