Does all the years of 240sx share the same brake piping system/sizes? I am mainly wondering if the braking lines system use the same pipe size, and the nut’s thread size/pitch? I went to Nissan to order a T-block which takes one brake line and splits it to two lines. The parts guy said it’s for a 97 but can’t guarantee that the S13s use the same one. This t-block is the same block that’s used in the rear of the brake system where one line coming from the front gets split into two for the rear two brakes. I can’t imagine it not being same. Can someone verify? ---

I believe that all japanese fittings are the same and the tube size doesn’t change either, so you should be okay. ---

There is only one 5/16" line on the 240’s brake system… All the rest are 3/16’ line with a M10 x 1.0 Inverted Flair Fitting.
