rear brake line diameter
 

I need to replace my rear brake line from the m/c to the rear axle. My shop manual shows its a 3/16" line.
Now the question - is that inside or outside diameter???

Dont forget...if you need to cut the line to fit it takes a double flare...takes a special toll to do this...

The other day i needed a brake line union to finish up my truck....the guy at o'Reilly tried to sell me a compression coupling for copper tube...we had a loud arguement about it....moral is use only the right stuff...and I just added it to my summit order...and got the right parts...

thanks for the reminder. ive flared many lines and have the correct tools.
seems like too many parts counter people don't have a clue.
when you find a good one, use them.

I believe in most states it is illegal to use compression fittings on brake lines.

Tubing is referenced outside diameter and pipe is inside diameter. ! 1/2" tubing will fit inside 1 1/2" pipe.

ok, so I got a replacement 3/16" brake line. tomorrow I may be able to re route it, cut & flare the end. so wish me luck. I really want to start driving this beast !!!
