Shouldn't the resevoir for the brake master cylinder be divided, one side for each circuit? Also, why is the resevoir for the brakes so large? Could a shared resevoir for both brakes and clutch be used? I need to do something about my brake resevoir in order to accomadate an aftermarket FPR and intake manifold, as well as learn a little bit more about the system.

You shouldn't be jimmy riggin your brake/clutch system. Your life depends on it.

You never know, it might be possible, but both systems are different.

I'm sure the fluid requirements of each are different too.

The piston divides them axially, front and rear. Look at how the piping comes off the cylinder.

Because you have disc brakes, each of which wears ½" before replacement, or 4" total. You should run short on brake fluid once before replacing pads.
Could a shared resevoir for both brakes and clutch be used?
Not for general street use, the public's too lazy. If it were a track setup, or a vehicle maintained after every ten hours of use and the brake fluid flushed out every week, it'd be okay. But it's not a good practice to intermingle brake and clutch fluid- the clutch flushes back-and-forth all the time, while the brakes don't much move. You don't want the worn clutch cup debris to get into the braking plumbing.

Look into the Mazda masters that use a remote resevoir that fill the master through a tube.
as well as learn a little bit more about the system.
None of us can learn enough. It's been forty years, and there's still acres I'm stupid about. I only know that automatic transmissions work by warlock spells.
 
I put my Aeromotive FPR where the FPS solenoid is located. I live in Texas where it gets hotter than hell and still needed to keep the FPS, so I mounted it to the backside of the bracket I made for the AFPR. Worked great for me, but I still use the OEM intake mani.

Yea, I will have to show you a pic. I know I could just mount the FPR somewhere else, but would like to look into this option because with the venom mani I can't fit it like you.


Defiant- How does the remote resevoir work? Is it still placed above the master cyl. or is there any point where the tube goes below the cyl.? Is it feasible to have the resevoir lower than the cylinder as long as the system is filled with the resevoir above the master cylinder, and then lowered and bolted into place?

This car is not going to see much driving at all, probably less than 10 hours every two weeks. Keep the ideas coming.
