Since the 79-81 280ZX BMC is almost unobtainium I was wondering what others have done or are thinking about doing?

1. Is there any advantage to using the Wildwood 1" BMC as outlined on the HybridZ forum?

2. Should I wait hoping that supplies will become available again?

3. Is anyone running the Toyota 4 pot front Brake calipers and stock rear drums with the 7/8" stock 240Z BMC?

If so what is the pedal throw Like?

By the way this for a 1973 240Z

Forgot to include some info

Is the MC not available anywhere?

I had one and did not realize that they were rare. I gave mine to Les at Classic Datsu.

They seem readily available... Check black dragon auto parts. They have them in stock.

Hi Gully. I am having the same prob. I have new Toyota 4x4 calipers ( early, narrow ) and will mount them on stock rotors. I wanted to get the larger bore 15/16 master, but no luck anywhere. ( Black dragon is back ordered too. ) Due to the increase in pedal effort with the larger bore, I was going to try a universal, double diaphragm booster. Around 100.00, and the firewall mounting studs are stock 3 and 3/8s centers. The one prob. with this is that the master cyl. studs are the same 3 and 3/8s. ( Stock being 2 and 1/8 ) Soooo... because of the unobtainable 15/16 ZX master, I am searching around for a 15/16 master with 3 and 3/8s mounting studs, that will work on the 240Z system. ( 1971 HLS 30 - 39379 )

Another option is to buy the '82-'83 MC and get the Brake Booster to go with it. I think that this method requires drilling a couple of new mounting holes in the firewall though.

Yeah, I'm thinking that will be the less painful rout twsutt. My firewall has already been drilled. I went this way before, but they sent the wrong booster. It was 10" in dia. and it threw me off, so I sent everything back. Doh!

I've seen the 10" booster before, what's that from...a 2+2 or a 280ZX perhaps?

Pretty sure it is from the 2+2.
