A One Inch Diameter Brake Master Cylinder for the S30 Z Cars

Recommended Posts

Be warned, the adapters from Flyin Miata are no longer the correct part for this swap. From the description "Adapters have an M10x1.0 inverted flare female fitting and 1/8 NPT (1/8-27) male on the other."

I had to cut my lines and install new fittings, not  a hard job but definitely ruins the day when you were expecting a 30 minute job and it turns in to a 2 hour job.

I did this upgrade several months ago and have one minor note to add. I just now removed the cones from the outlets on two 280ZX master cylinders. One of the 280ZX MCs had been on my 240Z with vented Toyota front and 240SX rear brakes for two years. The other 280ZX MC was an old one I purchased to use as a core. The 280ZX has front and rear disk brakes and yet I found residual check valves in the front and rear outlets of both 280ZX master cylinders. Thanks for sharing the nice information.

By cones do you mean the rubber residual check valves or the cone shaped seats the brake pipe seats sits on when mated to the mc?

 

And yes every 280zx mc I took apart had the rubber residual check valves.
