The 929 Brake Master Cylinder is a popular upgrade on the RX-7 FC and FD especially when going with a bigger brake upgrade of wanting to be able to apply more brake pressure for the same pedal travel.

*Some Modification of the brake lines will be required depending on your chassis application, some information on this can be found below.
Please note that you will require some show custom hard line making up in order to adapt your new 929 master cylinder to your RX-7, If you are not confident in making brake lines then we would recommend you get a professional to install this upgrade for you.
If installing this in your S5 FC3s you may be able to bend the stock lines to fit, you will want to also use the stock RX7 brake proportioning valve that is found on the bracket next to the master cylinder.
If installing on an FD you will need to make some short custom hardliners in order to connect to your stock brake lines along with a requirement to replace the brake fluid reservoir that comes with this cylinder with your original part as the FD clutch system requires a fluid feed from the fluid reservoir.
