do i need metric fittings for the brake pipes and lines or imperial.

I would guess metric, but it depends on what thoes 2 vehicals originaly had, i know there is a thred or two on these forums where they did this simular setup.
you might even need adapter fitings to allow conection of 2 different size lines. just my thoughts.

When I was making up a new brake plumbing system I discovered I couldn't buy the fittings to put on the new tubing. Reason explained was they (whoever they are) don't want us to do that because it is assumed we don't understand the concept of double flaring and certainly don't want to buy the tool to do it... Should have seen this coming when they wouldn't sell me "brake line tubing" for the same reason but found out I could buy fifty foot rolls of "steel tubing".
However I could buy short lengths of flared tubing with the proper fittings on each end, so I cut the tube and robbed the fittings. Started saving all used fittings from then on.
Does this help? Hope so.

Jeff, I want to do the same type of big brake set-up. I saw it on the web, but it disappeared-good thing I printed it out first. I am collecting the Volvo 240 vented calipers, but don't exactly know which what diameter the Honda prelude rotors need to be. Those will be cross drilled/vented and new. Also need to combine 2 lines from each caliper into one line. Did you need to go to a bigger master to feed the greater volume of the 4 piston calipers? Were there any other hurdles you had to jump? thanks for all the info, Gerold

Dear Nick, I would like to know more about the Metro master, and where and how much the rotors cost. Thanks for the info-gerold

Volvo calipers are buble flare, not inverted flare like the Opel. You can use the existing fittings however you will need an IF to BF adapter to resolve the problem. The rest of the installation I have posted many times and can be found using the search function.
