pl521sss Posted February 3, 2008 Report Share Posted February 3, 2008 In need of the rear 521 brake line. Line that runs on top of the differential. Also the T block also mounted on the differential. Link to comment
DanielC Posted February 4, 2008 Report Share Posted February 4, 2008 The brake lines on a 521 are standard 3/16 SAE brake lines. Any auto parts store should have lines, and the fitting you need, If the truck is still stock. Your truck is 38 years old. There is a reasonable chance somebody changed something in the last 38 years. Link to comment

There is a reasonable chance somebody changed something in the last 38 years. All Datsuns use 316 SAE lines? I tried using brake lines from my spares and didn't seem to fit right on the T block. This is when I screwed it up more by damaging the tread on that block. Now I have 2 problems, T block and the actual line itself that runs along the rear diff. I have not done tube bending on my own to replace them. That's why I'd rather use a line that has similar bends like from the other pickups. Link to comment
DanielC Posted December 25, 2009 Report Share Posted December 25, 2009 (edited) No, the threads on Datsun have been changed a lot. I believe one of the changes made from the 521 to the 620 is that the 620 pickups are all metric. A 521 pickup is around 40 years old. There is a reasonable chance the dreaded "previous owner" changed things. I was working on the rear brakes of a 1970 521 I own, and found one wheel cylinder that had a metric 10 x 1 thread for the flare nut fitting. The brake line from the block on the axle to the wheel cylinder was a custom made one, with an American 3/16 flare nut on one end, and the metric 10 x 1 flare nut on the other. I also found wheel cylinders marked 13/16 that were actually 3/4. I have found that some 521 parts are getting hard to find, and many times an easier to find 620 part will physically bolt up, with a change in fasteners.
