Brake Master cylinder

[shlammed]

Is there a 3/4" brake master cylinder that is more compact or that has a larger reservoir that I can make work in my '71 510?

 

I am adding ABS and want to have a larger combined reservoir if I can but need a smaller volume cylinder than some of the later boosted masters would have to keep a reasonable pedal pressure.

 

Plus disc front and rear.

Ah... the Limestone City. 

 

After the 510 pretty much all Datsuns increased the master cylinder sizes and added a booster to compensate for the added effort. My 710 was 13/16" and I imagine the 610 was the same. Not seeing how adding reservoir volume is needed with ABS. Once brakes are applied more fluid is not needed and cannot be added to the system. All ABS does is cause a pulsing hydraulic pressure in the system.

 

Assuming the ports are all the same distance apart you might be able to put later larger twin reservoirs on the 510 master. 

 

   

Or get two of these front reservoirs...
