Okay – I am getting ready to do my cobra brake upgrades and want to check I have got this right.

Plan is to use a 95 Cobra Brake Booster, a 95 Cobra Master Cylinder and install a line lock at the same time.
I also have the Maximum Motorsports 3-2 port conversion kit.

I also have the 95 Cobra Prop Valve - should I use that or stick with the stock prop valve?

Here's a picture of the new stuff that I can use...



So here are my questions – I have 3 diagrams - can you tell me if I have this right??

Diagram 1 – what I have now. Is this correct?





Diagram 2 – after the 3-2 Port Conversion




Diagram 3 – after the 3-2 Port Conversion and Line Lock.




Do I have these diagrams correct? Any suggestions or advice on this??
I am using the Hurst Roll Control and the Summit Line Lock Install Kit that has several line with it.

Thanks

Your diagram will work. If you already have the parts, then do it. I also used the summit line lock, but did not use the 3-2 conversion piece. I made my own lines, one from the master cylinder to the line lock, then used to exit ports from the line lock to go out to both front brakes. But like I said, if you already have the pieces, use them. It is easier than making your own.

Stock with your factory Fox prop valve. Just gut it (and install adjustable PV on firewall) and then use the MM 3-2 conversion to use it with your 94-95 Cobra MC.

The SN95 prop valves have different size fittings out to the chassis, so unless you feel like like cutting and reflaring the body lines out to the front pass brake and rear brakes, it's easiest to stick with the stock Fox PV
