If I really stand on the brakes I will get the back to lock up, but this is with a close adjustment, and I did not want drag on the rear so I backed it off a bit. I think that the fronts are still doing 70% + of the stopping.

Thanks, Roy.
With the 13/16" cylinders, can you get the rears to lock up before the fronts? Or a rearward brake bias?

Did not notice any difference, however, the brakes weren't really functioning very well. All 13/16 now.

Roy,
I gather you didn't notice the asymmetry until the rebuild?
Did you go all 3/4 or all 13/16?
Any apparent difference once changed?

I actually have a 67 1600 and when I went to rebuild my rear cylinders I discovered I had a 3/4 on one wheel and a 13/16 on the other. 13/16 is stock and now hard to find and expensive, but I tend to follow what was originally engineered and designed for the car.

Any update to this vintage 1999 thread?
http://www.team.net/html/datsun-roadsters/1999-11/msg00700.html
Are there functional, plug-and-play substitutions for the late roadster
3/4" rear wheel cylinders from other period Datsun brake parts?
Such as rear wheel cylinders from the 1200, B210, 510, 617, 710?
Did the debate over how to get more braking action at the rear (by using
either 11/16 or 13/16 cylinders) ever conclude?
Thanks.
