AFAIK, no one sells any pre-bent brake lines for the 544 Volvos,

I could not find anyone selling any brake line kits either, but 1 of my suppliers sells some of the lines individually.

The brake lines come pre-made with new fittings and the correct flares, but not pre-bent and are supplied coiled into loops which is the way Volvo used to sell them.

The brake lines are not steel but are made of NiCopp, which is a combination of Nickel and Copper which is much more resistant to corrosion. FYI, Volvo also sold the lines made of NiCopp.

I can get 5 of the brake lines for around $90.00 which are all of them except the line from the brake master to the reservoir.

There actually is a special brake fluid compatible hose that is not bulk hose, but a molded hose that has 2 different size openings. 5/16" to go on the stock brake fluid reservoir and 3/16" to fit over the metal brake line that goes down to the reservoir.

But what most people don't know is that the end of the metal brake line needs a single or double flare on the end because the inside of the special hose is made to seal on a flared tube end.
