245wagon Thanks a lot for your hints, been having a look through rock auto for parts, I cant see where they sell brake lines to suit the calipers. Do others sell them or do they need to be made up as custom?
Are you referring to the flexible hoses for the brakes or the hard lines? RockAuto probably doesn’t have either. If you want braided stainless steel flex hoses to replace the original rubber hoses, I have had good luck with the Technafit lines from FCP Euro. Very good for the price. ipd sells SS ones as well, or you can buy HEL lines via various vendors. The Technafit are DOT approved and hence legal in Australia and are the least expensive option for SS, or you can go with standard rubber replacement lines.
You would need 4 front and 2 rear hoses to make a set. ipd’s set is pricier at $169.95 but probably a bit higher quality. Not worth it for more than double the price IMHO. Note yours being a 79 you should be OK with the hoses listed above. The only dramas I’ve had are on the 93 240s where the non-ABS cars got 2x ABS-style hoses in the rear for the last run of production.
On the 240 there are 2 small hard lines between each front caliper and the flex hoses - I’ve had trouble getting these undone from the flex hoses even using a proper flare wrench, so consider ordering some of the hard lines as well or grab some from the wreckers to have as spare. Not sure where you can get new ones at the moment. The hard lines would need to be bent to the correct shape using your original as a template. Hope that helps.
