Leaking drivers rear brake line repair

[Awdtsi42o]

Hey guys,

My first post here I just joined the forum and it looks like a great place to be. Looks like a really great community.

I just purchased a 1992 toyota 4 runner and this is my first toyota and first SUV, I have only owned cars in the past.

The 4 runner I purchased has a leaking brake line which is the rear driver side. The leak is close to the wheel with a foot are so. I left a deposit on the truck and I am going to pick up on Thursday. The seller lives about 50 miles away and I am trying to avoid having it towed. Right now the truck has no brakes whatsoever so I cannot drive it home.

I am going to ask the seller if I can repair the brake lines in his driveway so I have limited time working on it. I have been working on cars all my life but like I mentioned before this is my first truck so it's new in some ways. I am thinking that I will have to fabricate the section of leaking line myself because there probably isn't a premade line that I can purchase locally.

Basically I am looking for any tips, guidance, or advice that may help me while doing this repair. It looks like I am going to have to take it apart at the wheel cylinder in replace that section of line. for those of you who have done a repair like this before any advice that you can offer it would be great I know that due to the heavy amount of rust this is going to be a pain in the ass.

Please let me know if you guys have any pointers or anything that might make this repair go easier I am hoping that I can do this in minimal time since the vehicle is still sitting in the sellers driveway. Is there anything I should be aware of before doing this repair?

Thanks very much and thank you for letting me be a part of this community.

Danger will robinson. Danger.

I have personally rebuilt the entire brake system on a 1991 4runner, so I know exactly what is involved.

You can purchase pre-made lengths, but don't. It is actually more harmful, than helping. Standard, DOT brake line is sold at auto zone or other car place. I don't remember the spec line diameter on that year runner, google or look in the service manual. I can look later.

Learn how to brake line flaring before you go to fix it. If you already have the tool and are confident you can do it, more good! I bought a 4 foot section of brake line and spent an entire night, while watching TV flaring the line. I got to the point I could do it blindfolded, because if you end up needing to cut line up in a wheel well, you will need to know how to flare very well.


You sound like you know about cars, so it shouldn't be too difficult. Buy brake line and a couple of fittings, both male and female. Get comfy with flaring and you should be set.

You will need to bleed the brake line as well. Buy a large can of brake fluid, buy a self bleeder. All it is is a little tube to help you bleed it.

Other than that. A haynes manual will have some pretty standard rules for the brakes.

if your worried about bending the tubing or just trying to get it done real quick just go to ur local junk yard and buy the piece of tubing off of a junk runner and stick it on yours shouldnt take 10 minutes then if you are worried about it when u get home and have more time then you can bend a new piece and replace it with a whole new piece. just an idea for a quick fix so that you dont have to spend a lot of time in the guys driveway.

After you replace the line you will have to bleed the entire system.
If you've never done any of this before, it could take you most of the day.

If its leaking at the rear drivers side, it's a short piece from the wheel cylinder to the T-block on the axle, easy to get to and you could bend that by hand. Are you sure it's the brake hard line and not the wheel cylinder?

Hey guys,

I repaired the brake line section that was rusted out and leaking yesterday. However, after repairing the section of line that was rusted out, an additional line blew out while trying to bleed the brake system.

I am at the point that I think it is better to replace all of the brake lines because at this point it is a safety issue. Does anyone have any advice, suggestions, or tips that has done this before? (replaced all the brake lines on a 92 Toyota 4Runner)

Any advice or suggestions would be greatly appreciated I have not done much work with brake lines in the past but have been working on cars most of my life. I am looking for tips on strange things or problems I may encounter while doing this job.

Thank you very much for any help you can offer,

Erick
