vettespeed Posted July 16, 2012 Report Share Posted July 16, 2012 I have a 1966 Datsun 520 pickup and need wheel cylinder kits and front brake flex hoses. When I get on any major auto parts store or ebay database/website everything basically cuts off at 1967. When you search 1966, nothing comes up. The 1966 didn't actually have different brakes than 1967 and later 520's did it. Nobody has any of the 1967 parts in stock for me to compare. Thanks, Mike. Quote Link to comment
ggzilla Posted July 17, 2012 Report Share Posted July 17, 2012 1967 model year is when they changed the brakes. The changover was Oct 1966. 1966 had 3/4" cylinders 1967 had 13/16" cylinders front brake hoses are different too Rockauto carries front 3/4" under 1967. Inpsect yours to make sure of the size, it should be cast into the cylinder. Get the rebuilds, you'll be glad you did. Or disassemble the cylinders and if they aren't pitted, the kit will be fine.

datzenmike Posted July 17, 2012 Report Share Posted July 17, 2012 There were 13/16" or 3/4" wheel cylinders for the front and rear of the 520. As long as they are all one size it should be fine. Front and rear flex hoses appear to be the same and will interchange Quote Link to comment
vettespeed Posted July 17, 2012 Author Report Share Posted July 17, 2012 All (4) of mine are 13/16", does that mean they've been changed to later model stuff? Most of the kits don't specify bore size, they can't possibly work for both? Quote Link to comment
ggzilla Posted July 17, 2012 Report Share Posted July 17, 2012 Well the bore size only affects the pressure, but the brakes will work just as well. Datsun might have juggled the M/C size that year. I don't buy kits that fail to specify the bore size. It's difficult enough to find the correct kit. My parts catalog says the front brake hoses do not interchange between 1966 and 1967, but Mike might have a better knowledge. Quote Link to comment
datzenmike Posted July 17, 2012 Report Share Posted July 17, 2012 My info says front brake hoses ony have one numer during those years so I assume they are the same. I didn't check the hard lines... maybe standard to metric change ??? Quote Link to comment
vettespeed Posted July 18, 2012 Author Report Share Posted July 18, 2012 Well I ordered in flex hoses for a 67 and they were identical. So either they are the same or I had 67 stuff on this truck already? Thanks, Mike. Quote Link to comment
Benlt Posted March 20, 2013 Report Share Posted March 20, 2013 Sorry to bring this post back from the dead but I am having some difficulties with my 520 brake parts. I ordered some new master cyls for my 66 520 from rock auto, the wheel clys fit just fine, but the hoses were not the right thread on the male end that screws to the banjo bolt on the wheel cly. Can I buy a banjo bolts somewhere that fits this hose? Quote Link to comment
