hey guys, im pretty new to this but wondering if someone could help me out, i bought this civic and just fixing it up before the winter, both of the rear braklines went on me and i need to rerun them. i need to know how size the lines are? i cant find it anywere iv searched google like crazy, also its a 91 civic DX hatch.

thanks, mark

 

well if they are rusted out just CUT a good piece of that steel hose out and take it to your local parts store.......

and if you can... not sure WHERE your hose is rusted thru but follow that line to a bolt conection and BE SURE TO USE BRAKE LINE WRENCHES cause if the line is rusty they will be VERY EASY TO STRIP!!!!!!!

and use a brake bender so you dont put kinks in the lines when bending them to fit the car...
i had to replace a rear crossover line on my old 86crx. wasnt to tuff as long as ya had the right tools and also be sure to get the right brake lines before bending them!!!! be sure the ends are the right size and thread cause if you bend them and they gave you the wrong threaded lines or wrong size they wont take them back... thats why its best to take a piece of the line with the threaded end so you can be POSITIVE its the right size line and threaded ends...



o ya also be sure to use some teflon tape on the threads.... just EXTRA security from leaking...

 

Absolutely use a flare nut wrench. It's guaranteed to round off the nut if you use an open end wrench. For old rusted ones, cut off the line at the fitting and then use a 6 point socket to get the fitting out. You should still own a flare nut wrench to put the new line on.

You can buy exact replacement lines from the dealer. The longer ones are kind of expensive though.

They are standard metric thread you can buy ready-made straight ones from a parts store. Find the ones with 10mm hexes on the nuts.
