I replaced a claiper and flushed my brake system with new fluid then a day later my brake light comes on. When I finally read that this is brought on by low brake fluid level, I checked and found it was almost empty.

Refill the resevoir only to find that it would start to drip out after about 5-6 pumps of the brake pedal.

It drips on the drivers side, just behind the drivers door and can be seen without having to stick your head under the car. So I assume that this is the line that leads to the rear drivers side brake.

Are brake lines easy to replace.. ie: follow the line and replace with a new one? I was told to buy a 15 foot length of line and the fittings and thats all.
Is it a straightforward job, or awkward to get to?

Thanks guys

 

are you sure you didnt just forget to tighten something?? i mean where is it leaking?? at a fitting?

 

all the rear lines run right where your drescribing the leak so its proboly one of those but you might want to replace both while your at it

i think you might have to drop the gas tank but im not 100% on that

 

I know I didnt forget to tighten something since its dripping just inder the car behind the drivers side door..

I find it strange that it just started leaking that badly so quickly..

 

Well w/o knowing exactly where it's leaking, it's sorta impossible to help ya. Guys here have changed their brake lines. Wasn't their idea of a good time though.

 

I'm guessing that your brake line is rusted through. Seems to be a recurring problem with the brake and gas lines that are used on 3rd gens. I don't know if the metal rusts easily or if the guard over the lines helps to retain water and salt, etc. Once you crawl under the car and remove the plastic guard, you should be able to see where it is coming from. I replaced all of my fuel lines and brake lines. Jeff is right, it wasn't a good time. My lines were only rusted really bad for about a foot or two right under the drivers side door. The rest was ok. If I had to do all over again I would just replace the middle of the lines. It's not really the best fix, but I drive a TON of miles so I took the hard route.

 

I agree with Gregor4. I had a brakeline rust out on another car where the line passed behind some firewall insulation. It seems the insulation would hold moisture after a rain and after awhile the brakeline sitting against the insulation rusted thru. Follow the brakline down from the master cylinder and look for rust then check it for dampness.

If it has a hole you can replace the line but it may take some finesse to bend it to fit. Just make sure you get the correct type brake line as thee are different type. A "good" parts house can get you the right type.

 

The guard does trap water/salt/mud, which is about 5 ft. long. On my car, all 5 lines (3 fuel, 2 brake) were rotted almost completely along that stretch. I replaced everything from about the firewall back. Very unpleasant, but at least the car is safe now. The brake lines I could bend by hand, but the fuel lines were larger, one was 5/16 i believe, and I used a tubing bender for that. I used union joints where necessary. Good luck.

 

I bought the nissan steel brake lines and when I got under the car and removed that plastic guard I saw that the 3 fuel lines are rusted to hell with a very fainth gas smell there.

I realize that there is no way for me to replace the brake lines without harming the fuel lines. After having inspected the brake lines, I regret not having bought generic lines because I have no idea how I will be able to bend them to fit sinc ethey are so long and bending all over the place.

Im thinking I will replace the fuel lines with a generic fuel line...

What was nissan thinking by using a vented guard and not a solid one that would keep salt and water out?

 

What everyone of us are thin king? Fast Cash. "Let smbdy else carry the heat" (or here the rust). In that mode, we're all animals - but that can be changed, every individual decides if.

When buying a car, these places should be checked FIRST. After getting, opened, dried, (oh boy no:welded), oil sprayed. Fluid change; cannot do too often: imagine the rust NOW traveling in u system and building a jam-dam somewhere...

This is the worst place; thats why I added some shields. But if not cleaned yearly, they'll themselves become the problem. And oil spray all under...
