Not entirely correct 1949 Caddyman. The left front, right rear, split is NOT how all vehicles are. Both my 1996 C1500 and my 2001 Impala have it set up as left and right front on one resivuar and the rear on the other. I'm 100% positive on this because I've blown brake lines on both vehicles, and you either lose both front or both rear brakes, depending on which line you blow.
I still agree, though that you NEED to keep two lines going to the rear. This is because you have ANTILOCK brakes or traction control.
Another tip, if you are replacing lines, use the copper nickel alloy lines instead of the steel or stainless lines. once you've used the alloy lines, you'll never use steel ones again. The alloy lines won't rust out in a couple years, and they are way easier to bend and flare. Also, when doing a line repair, just do the entire vehicle if you intend on keeping it for any length of time. No sense in patching one section when the rest is ready to blow out as well.
