Brake Line Size

[mediabandit]

I need to replace the rear brake lines on my '98 Lumina ls, from the drivers door back. Is it 3/16" brake line i need to pick up? They do not sell it in rolls anymore so i have to buy it separate in different lengths and connect them together. so it makes it much harder to do dammit.

i believe it's 3/8, not 3/16, but it's been a year or so since i've blown a line, so i'm not entirely sure.

3/8" is more like fuel line. Brake lines on the car are 3/16"

Hi, replacing my sons 1998 Lumina with a little over 250,000 miles on it rear brake lines found some 25' 3/16 kits with fittings online I have a line bender and cutter and a flare kit ,, replacing rear lines this weekend hoping its 3/16 as posted. I'd get rid of it but that 3.1 just runs like a top and the trans is still smooth. I've rebuilt all four corners and a handful of other items over the years but its a former grandparent car so it was well maintained and we have done the same.  This series of 3.1 3.8 V6 chevy cars was almost bullet proof I still see a ton of Luminas, Monte Carlos, Corsica's on the road and setting on driveways.
