Had a rear passenger side brake line blow out from rust on my 89 GL sedan.I think im going to fix at home by putting new tubing from the "t " fitting that splits them on the drivers side,to the rear flexible hose on the passenger side..This to eliminate all the crazy bends.This is going to be a cheap fix i hope as this next NY winter will likely be its last(dam salt).What are the end fitting sizes I need to go into the splitter,and the flex hose? Are they metric?Also what size is the brakeline?

What are the end fitting sizes I need to go into the splitter,and the flex hose? Are they metric?Also what size is the brake line?

 

What I do is measure the length I want, and go to my local auto parts store and ask for "10mm Japanese" brake line in the desired length, they should have it there.

 

There are two sorts of "metric" brake line, European (with the "bubble" ends) and "Japanese" with the conventional flare ends, and of course you want the "Japanese". The thread is 10mm, I have only seen 1 size of brake line that goes with a 10mm fitting, it is really close to 3/16, I do not know the metric size.

Thanks for the info!
