    Ok, I got my brake system mostly figured out. 55' m38a1 /cj5

    1. Upgraded to the dual MC
    2. Upgraded all brakes to 11" drums

    I want to buy a preformed brake line kit from Morris 4x4. Which year should I get? Whats the difference between 72-73 and 74-75?

    Thanks!

    Likely the '74-75 expects a combination valve (proportioning valve and brake warning light) that the '72-73 does not have.

    My feeling is that neither of these kits are going to fit very well. They use a master cylinder mounted to the firewall with swinging pedals. And the wheelbase of these Jeeps is a little linger than your M38A1.

    Custom brake setups pretty much demand custom lines- there's too many variables to guarantee that a line kit for a particular year will fit your setup. I used preformed lengths from the FLAPS & bent, and where necessary on one or two, trimmed & re-flared them to fit.

    I got the copper coated nickel brake lines from the auto part store and bent my own. They are very easy to bend and 1/3 the cost

    I really like having a bulk roll of tubing, with some various nuts, and bending my own any time I need to. The double-flaring tool was a good investment.

    Actually those copper coated lines are "Cunifer" or "Nicopp" and appear to be the same copper-iron-nickle alloy all the way through. eBay is the cheapest source for coils of that material. It is easy to bend and flare and will not rust. More expensive than steel though. I have made custom lines with it and had excellent results.

    I agree with PeteL. Bulk roll of tubing and a flaring kit is the way to go. It is the easiest way to run the line where you want them with custom bends; that way you are not fighting preformed bends that don't line up where you need them to go.
