R32 Brake Brake System, Need Some Help To Identify And Advise

[DatsunMotorSports]

I have a brake booster and master cylinder from a R32 clip. Im considering installing it into an old S30 chassis(zcar). It almost bolts into the firewall and the pedal linkage works. The master cylinder has a built in "proportioning valve". I was told it came from a GTR, but I think it may have been from a RB20DET equipped R32. The master cylinder looks like it was a Non-ABS equipped unit. It has 3 lines coming out of it. One is at a 45* angle. It apears that the rear 2 are the front left and right while the farthest forward is the rear brakes.

I would like to see if anyone has a clue as to what would be in the rest of the brake system. What valves would I be missing, etc. Id almost guess that there isnt anything else in the system other than the master cylinder.

Can anyone shed some light on what system I am dealing with?

Anyone have a diagram for that system and what components make it up?(or even a list)

If it will help I can post a picture of the unit.

Worse comes to worse I will bolt a S130 (82-83) master cylinder to the booster and use that. (the brake booster is far superior to the single diaphram that came on my Z) I need a larger cylinder to support the larger brakes Im going to install.

Thanks for any help you guys can supply

its might still be 32 gtr, there are only 3 lines from it (2x front, 1x rear). but ultimately there is nothing special it is just a master cylinder with a given diameter (11/16th from memory but you could confirm with a search in this section). Are there any markings on it, I can check part numbers if required.

not sure about other components I have never got around to removing the whole system at one time. the rear certainly has some mounting blocks but afaik it does not include proportioning valves.

if you are doing a custom setup (sounds very custom to me), I would use the master cylinder you have (assuming it is big enough for the caliper pistons you have), the booster you have, and an adjustable proportioning valve in the rear circuit to deal with any bias problem that turns up

you need a gq patrol cyl. 1 1/16" no prop valve bolts right up.

gtst is 15/16 gtr is 1" gtr with brembo is 1 1/16" bm50 gtst bm54 gtr bm56 brembo.

non abs cyl, front 2 are the front and the single one is the rear. abs has just 2 and differant prop valve.
