Does anyone happen to know the exact nut and tube size for the brake line on the rear of the driver site. Mine is broken and I’m trying to get a replacement but it appears there are many different options for these vans. Also, is the place one can buy the complete tubing and nut assembly? Any help will be highly appreciated.

 

Dorman may make line sets. You can also look at the brake hose listings on their website to figure out fitting size.

 

Should be the one:

Bought a complete set from here:

Comes pre bent with all the hardware. Needed a little tweaking to get them right. If one line has issues, the rest will follow. I just changed all mine after rear ending some women on a local street. Pedal went to the floor. Damage minimal, but more excitement then I need or want. The three flex lines are not included.
Big issue was(is) the ABS module. You need a bi directional scanner to bleed it before you can bleed the rest of the system.
