1" or 1 1/16" Datsun M/C? Anyone?

[ZSaint]

I know the Z32 uses a 1 1/16" master cylinder. It will not fit the Z. Does anyone know of a ZABCO-type cylinder that will fit a Z that is extra large? 1" or larger? I need more fluid travel! :cheeky:

I think you will have a hard time finding one as the housing will be larger so the bolt holes will be further apart. So, crazy idea time, just went out and measured my 91 GMC Jimmy's MC, the bolt holes are the same distance as are the side bolts on my 73 booster that the adapter plate bolts to. I wonder if you were to remove the adapter plate if the Chevy MC would work??? Maybe just needing adjusting/modifying of the booster pushrod?? I'd do some measuring on the Z and then head down to the pick and pull with some wrenches and take something apart there and compair the measurments. You're running Chevy brakes, why not a Chevy MC??

One off an old Nissan Patrol 4WD fits straight on, 1" ID. Don't ask which model Patrol, think it had drum brakes all round. Just be aware they have (removeable) pressure residual valves, mine were binned.

Nissan Patrol 4WD??? I wonder what year (about) these would be? 80's? I guess I can go to the parts house and see what they have. How do you take out the valves? I think these valves are in the lines where the brake lines bolt to the M/C. Can you just take the valves out? (Did you mean 'pinned'?) I am guessing the front and rear lines are the same as the ZX M/C, right? I remember changing the brake lines on the 240Z because they are opposite from the ZX. Hope the Patrol is the same as the ZX!!!

I will check it out!

I went out today and fiddled with the brake pedal adjustment. I have all of the travel screwed in to the linkage. It is still too much travel. I will pursue the 1" Patrol 4WD M/C. I know the extra volume will help the travel. Thanks for all of your tips!

I remember (from my years in the brake repair business) that lots of Japanese vehicles from the '70s and early '80s used similar Tabco and/or Tokico cylinders. The Nissan Patrol was offered in the states only in the late '60s or early '70s. Might be hard to find listings in the parts books. But a cylinder for an all-drum brake vehicle is probably a decent way to go - wheel cylinders take more fluid to operate than discs do. Another possibility might be some Japanese car/truck that came from the factory with four piston calipers. I wonder what kind of cylinder Toyota 4X4s use?

[ZSaint]

The Toyota calipers have 4 small pucks. Doesn't take a lot of fluid travel to make these calipers work. 60-70 Nissan Patrol. I will see what the parts houses have for these babies.

I have found out that the Stanza uses a 1" M/C. Does anyone know if this will work? It looks like the same cylinder.

Binned=thrown in the rubbish bin/trash can

(Binned as in 'tossed'. Got it!)

I have purchased a Pathfinder 1" M/C. I now have a M/C that has the mounting ears side to side VS. the Up and Down ears on my 280ZX M/C. Anyone know of an adapter for this M/C? Any ideas? :paranoid:
