I'm hoping someone here can help me out. I am working on the brake system and was looking at the master cylinder, see attached pictures. Mine does not look like those from the FSM or Haynes manuals. One of the filler holes has a molded cover that does not appear to be removable. Any ideas of why this is different as I thought this portion was for the rear brakes. Do I need to pry this off and fill or do I just fill both through the main opening?

Looks like a normal 82-83 brake master to me...

The 79-81 master had the two reservoirs. Just about every car these days has one reservoir for the entire brake system (front and rear).

Thanks for confirming Nismo, that is what I was thinking but both manuals show two reservoirs. Just wanted to make sure I wasn't missing something as I learn more about this car.

Are you using an 82-83 FSM? I know there's a section covering the different brake masters (I'm at work otherwise I'd tell you the page).

I downloaded the manual for an 82, folder containing all the PDF's is called "82_datsun_280zx". In the brake section (BR.pdf) it has diagrams for NABCO and TOKICO makes but they both sjhow two reservoir caps, it's the internals that appear to be different.
