I have an 02 Civic LX which I picked up at the beginning of the summer. The current issue is that my brakes are leaking, and it's speeding up. I think if I refill the fluid and bleed the brakes I can drive for maybe two weeks. I was hunting for the source of the leak today, and I may have found it. It would be incredibly helpful if you could help me to identify which part I need to pick up, as well as potential instructions on swapping it out. Thanks so much!
Before I wiped it down. After I wiped it down. This is a picture I found online, but I've circled what I believe is the correct line.
Clearly that line needs to be replaced, but possible your not going to be able to disconnect that from the flex line so then that will need to be replaced..
Definitely suggest looking at trying to find a pick part junkyard and pulling that line out completely from a non-rusted car.
Those other lines don’t look like they are far behind..

That brake line actually runs up to the master cylinder, no flex line involved. My local Honda dealership has that line listed as $36, part number 46320-S5A-A02.
Haha, I didn’t even “see” that line due to contrast on my phone.. I was seeing the rusted out one weeping down the portioning valve backlit with sunshine..
Indeed that lower one needs to be replaced as well, what sort of hellish rust do you have elsewhere I can only imagine.
Thanks for the help thus far all. I got the line off, though it was a huge pain. Now i have to get a new line put in. I don't have the ability to go pull one off, so I'm just going to bend one myself. Due to time constrains, I'm not going to be getting tubing and flaring it myself, I'm just going to buy a line from Advance Auto.
I am very worried about the actual bending process itself. I have the old line to use as a template, but there's a ton of complicated bends in it, and I'm worried about getting it in exactly the same shape. How difficult is it going to be to actually bend something that's going to end up fitting into the car? Any tips? Thanks!

Re: 2002 Civic LX brakes leaking.
buy the copper nickle stuff its very easy to bend and pretty forgiving. and just take your time.
for that one crazy sharp u bend i may see if theres a different way to run the line without it getting crushed
Got the line (low-carbon steel) in today. Just did a simple straight run rather than following the complex bends of the original, since the car is basically a junker and I'm not so worried about keeping everything looking perfect. Only took two bends: a 90-degree at one end, and a just-under-180-degree at the other. So, we'll find out if that was actually the part of the brake system that was leaking, but at least I didn't break the car worse!
Hey all. So I still have a leak, but I do think I have the location down correctly. I think the problem is that the fluid is actually leaking out through the threads. Is there a way to fix this without replacing the proportioning valve? Perhaps if I used threadlock, or something akin to it? Thanks again!

Had same problem with my 2002 civic,had to purchase new proportioning block, new honda oem $120.00 ouch , i think problem arises with alum threads in block -steel threads on brake line fittings get buggered up stripped,also had all steel lines replaced new master cyl.,cost over $550.00 labor and $250 parts car is in N.E ohio
I had not done work my self as im 60 years old and disabled.,first garage tried to fix it,same way with new lline into old proporsioning block lasted about 2 months then blew out and started leaking again,second time went to a differt garaage with new proprtioning block,and new master cylinder,same aluminum construction,worried about threads stripping out on it,they installed those items that I supplied,along with lines and labor they supplied ,alli in all honda should have used brass for pro block like they did on older cars ,cheaper i guess,now have to get air bag recall done for the third time
Sorry to resurrect a year-old thread but I have a similar issue and I'm having problems finding exact answers.
I am a novice DIYer and as I was finishing my latest project on my 2002 LX 2dr (replacing a rusted power steering return hose), I noticed my brake line (master cylinder to proportioning valve) was leaking rather dramatically. I must have bumped it when installing the new steering hose. It's about as rusty as the lines seen in this thread.
Anyway for most of my DIY stuff I have found helpful and precise answers when doing my research, but for brake lines all I seem to be able to find for sale are generic lines that I have to bend, flare, and fit myself. I really would rather buy a pre-made "plug and play" line, but I have had trouble finding the size (3/16ths?) and style (bubble flare?) of these lines. If you guys could specify all the numbers that would help me. Otherwise I suppose I could go back to the junkyard to ensure a proper fit. Thank you.
3/16" is the size I used, and yes bubble flare. There are two lines going from the master to the proportioning valve, which one is bad? They are both under $30 each on Hondapartsnow.com.
Thanks guys I guess I should have considered OEM from the dealer. Of course I'm in Canada so probably double that price. I assume they're plug and play if they're from the dealer?
Anything else I should be aware of before replacing? I've already soaked the 2 flare nuts in penetrating oil, and I guess I will have to do a bleed after. Is cutting the line off and using a socket recommended, or is a flare nut wrench required?
Those prices were US by the way so they will differ for you. Yes you could call them plug and play, with a full brake bleed afterwards. I would definitely recommend a flare nut wrench but you can see how it goes.

Re: 2002 Civic LX brakes leaking.
Torontohondaparts.com will let you look up the parts in CAD. I've gotten stuff from there before. The dealer in Barrie had the same prices.
Try with the flare wrench first, if it tries to round at all cut the line and put a socket on it.
