Snowing today, but I will swapping the struts side to side. I ordered a 280z 7/8" master cylinder too. I think the 280zx 15/16" piston might be too stiff with a manual brake setup.

Good choice.

It is. 


It's your car, just don't ruin it.

 

It's also not my money, so i'll suggest the most expensive option.

And the zx had rear disc which will really mess up you brake proportioning with drums in the rear.

I yeald to the wisdom of Q on this one.

Fuck!!!!!!!! I guess QTip was right...

Master cylinders do not control brake proportioning.  B)

 

It has a bigger piston (due to the rear discs) which will just make your pedal too stiff.

I thought the 7/8ths was too stiff. I liked my 3/4". Probably would have gone to the 620 13/16th if I was still driving my car.

Honestly, with rear drums, I always run a new 3/4", Pedal is soft, but stops nice and is easy to modulate. Almost feels like it has power brakes.   :rofl:

^ this exactly, 3/4 is the way to go with rear drums.

I don't like the idea of swapping the struts side to side, it fucks with my ocd. I know caliper positioning has no effect on braking but the damn L and R stamped on the strut housing would be just irritating enough to drive me nuts. I've had T3 RCAs with both cut and uncut struts with no ill effect to handling. Maybe I'm lucky, but I drive my car like it's stolen and have never had the wheel ripped from my hands experience others have and my county has some 3rd world assed roads.

When I was running ZX fronts with drum rears, this was my setup.

Front: ZX struts with stock ZX calipers. Porterfield R4S pads, stock 510 3/4" master cylinder
Rear: 510 stock rear brakes with 240Z aluminum drums, Datsun 1200 rear wheel cylinders and Nismo green stuff rear shoes.

Man I loved this brake setup. Good pedal feel, not too much effort required to push the pedal and great braking ability.

Also, I've determined, I'm not a hoarder, I'm a collector.
As I'm sure a lot of the old school datsun guys are.



Enjoy the Ride!

This is why I love it. Easy effort, but still very good braking. 

 

 

I got the 280z master already, just going to roll with it.

 

It's not bad, in fact this is what a lot of people like. It makes pedal throw a bit shorter and the effort a bit firmer.

So many variables 3/4, 13/16, 7/8 and 15/16" masters. Stock z, zx, S110, S12, 720, D21 even Willwood calipers. Drum or disc rear ends. Different vehicles (coupes/sedans/goons and trucks weights... 240/260 280z, 510/610/710/A10/S10/1200/ B-210/B-310/521/620/720/S110/S12  some with vacuum boosters. Some people's legs are stronger. The list of combinations is staggering.

If you swap zx struts into just about any other Datsun, the caliper movse in as the pads wear down and rubs the knuckle arm.  I believe this is what's happened to my struts... it has an unexplained pull to the left so probably the right caliper can't move properly.

 

If you swap the entire strut to the opposite side the caliper is now mounted to the front of the wheels and no where near the steering knuckle. This is what I plan to do.

 

If you are lowered, installing bump steer spacers will also correct the problem.

To really dumb it down even further than Mike did, put all the right side stuff on the left, and all the left side stuff on the right. Easy peasy.
