I like using the 25' rolls of brake tubing better than the ready made lines--for the reason the "bulk" rolls are made of much thicker gauge steel and usually have a better anti-rust coating than the lines already made up do.....also I have found on many later model cars & trucks,some had odball metric threads that cant be found on ready made lines,so your forced to re-use the old fittings,or spend days tritting to parts stores in hopes of finding a "adapter" that will make regular lines work--and even harder,finding an employee at such a store that isn't clueless and knows which fittings to sell you,if you dont know which one to get,then your pretty much boned..
My Ford Contour has 11MM threads on its rear brake lines,good thing I didn't try tightening the new lines I put on it after I noticed they felt sloppy in the threads as I was putting them in!-the new lines had 10mm threads,and 3.8x 24 threads would have ALMOST fit in too,but had I wrenched them tight I'm sure they would have stripped the brake hoses and calipers !..

..had to cut all the old line nuts off and re-use them,as NO parts store had the adapters in stock,which cost more than the barke lines did..:tolleyes:..
You will likely have yo re-use the line nuts on the master cylinder and junction block/proportioning valve over,there are 2 that have 9/16x18 threads that are not easy to find at parts stores,and adapters are expensive,IF you are lucky enough to find some with the right threads..
