2002 Frontier SE CC, 4x4, 6cyl 3.3, 6' Bed.
Trying to figure out the length of the line hard brake line that runs from the rear end to the connection near the passenger side shock.
Is it one or multiple pieces. Also, it seems to be 3/16". Please correct me if I am mistaken.


TIA

Going by the parts diagram, it looks like there is a metal line on each side of the axle that connect to a rear brake hose. See diagram:

2002 Nissan Frontier Brake Piping & Control - NissanPartsDeal.com

3/16" and 4.75MM brake line are close enough to be interchangeable. However, the brake line nuts may or may not be compatible, so you need to compare them. If they are not, you'll have to cut the end off of the line and transfer you old line nuts or install the correct line nuts and then double-flare the cut end of the line with a brake line flaring tool. Sometimes you can get the exact line size you need, but other times you have to get a longer line and cut to size. Auto parts stores will have the lines and fittings you need.

Thanks. I was hoping it was in 2-3 pieces, so making the bends may be easier.
I've replaced brake lines before on another truck, but this one seems to be longer and with more curves.

I just did all of the brake lines on my 2002, to make things easier for me to just buy lines off of the shelf, I used Dorman brake line unions (pt # 785-438 is the 10mm inv. fl.). That way I was able to use to shorter lines and for me it was a lot easier to get the bends right. They're cheap $3 and you can get them in a bubble flare (some of my connections were euro bubble and some inverted flare) or inverted flare all were 10mm.
