Replacing all brake lines (92 4Runner)

[Awdtsi42o]

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.

Are there any other weak points I should inspect or worry about? I am on a limited budget, I imagine I could go crazy replacing everything.

Thank you very much for any help you can offer,

Erick

I am not aware of any inherent problems with the brake lines on the 4Runner. But then again your vehicle is nearly 20 years old and could easily be affected by the environment that it has lived in. You are right, one leaking brake line is bad, two is a safety issue and something needs to be done. Replacing all the brake lines is truly a pain in the arse. It gives me chills and nightmares thinking about bending and routing all those stupid lines. Maybe before you tear out the brake lines, you should crawl under your truck and do a full front to back assessment of the condition of the brake lines. I would think that any potential issue points would present themselves fairly easy.

Our brake hard lines were fine on our 1990 4runner but the hoses were another story. So I replaced all the hoses, master cyl., rear brake cyl., and flushed out the fluid which seem to bring the system back to life. I've yet to replace the proportioning valve, but it could stand being replaced as well. These trucks are just getting to the age, where some need a light restoration of sorts. Having said that, the parts costs are not too bad, better then car payments, or payments on interest for loans.

I did this project recently on a 1989 BMW. I got some lengths of coiled brake line and a good flaring tool and practiced a bit before I got into it.
Having a selection of different diameter things to bend the lines around helped.
A cheap flaring tool is not your friend. I also changed to stainless steel flex lines. It wasn't too bad if you aren't in a hurry. It was good to minimize the number of unions and potential leak points. Be sure you get the correct ends for the correct diameter brake line.
