ok so i got all new wheel cyl on all 4 corners and hoses (thanks dattoman_1000) so blead the brakes but there still is not much there so thinking the master cyl is gone. when u press the pedal down fluid sprays out the top so im sure thats not right.
what other models came with the same master cyl that i wont have to ship from Australia. im using a clutch master cyl from 510 only diff is there is throw

Lets clarify.
Are you dealing with an A10 car, known in the US as a 510 [second generation 510, not the earlier P510] & known here in Australia as the 'Stanza'?

The code A10 also refers to an A series engine that was used in the B10 car. [Datsun Sunny 1000]

wops my bad i ment b10. ive had the engine on my mind to long.

so any master cyl thats will swap out between the 1000 and a 510 210 or something along those lines. the local parts stores dont know what a 1000 or 1200 is

dattoman_1000 is the guru on this stuff.

I think its the 13/16 sunny twin pot master cyclinder unit is the untimate bolt in upgrade for the 1k. Part numbers im not sure on.
