I have a stock 86 rx7, with auto-adjusting suspension. A little down the road I'm planning on changing over to regular shocks/springs, but for the time being I need to replace the brake master cylinder. If I get a brake master for the non-auto-adjusting will that work fine? or do I have to get the auto-adjust specific cylinder?

Also, are the stock calipers 4 piston or 1 piston? Not able to get to the car to look and I need to order parts soon.

 

Unless I am about to learn something new, I think there is no difference between the two...

 

Yep, I just learned something new.

*Something New*

And single piston if stock.

 

<3 Thanks that's perfect!

 

There are some differences. Lets say you are talking about brake masters for the 4 piston front brake non-AAS master and the AAS master, the only difference is that the master for the AAS one has a spot to screw in a sensor in the bottom of it. The non-AAS ones do not. I set mine to sport mode and unplugged the AAS computer. So I could have gotten the other one for less money :/
