Proper brake master cylinder sizes? Which size for clutch? Change pedal for hydraulic?

[Cobra4B]

The GTS manual shows the brake masters at 7/8" and the clutch master as 3/4". However our GTRA has a 1 1/8" master for the rear brakes and 7/8 for the fronts. My clutch is currently manual, but I'm converting to hydraulic for the clutch and have seen people use master sizes all over the map on here. I.e Wirewheel sold a clutch pedal assembly and line with a 1 1/8" master. What's the proper size? I wouldn't want to push too much fluid through the throwout bearing.

Here you can see the left master is larger


This car for sale on Wirewheel appears to have the same thing going on i.e. left one larger (center one in this picture, left brake master). What size is that clutch master? The reservoir is obviously smaller.


I assume I have to change the clutch pedal when I convert to hydraulic? Anyone know the specific part? I assume wilwood would make the parts ince our pedal bodes are wilwood. Again the Panoz parts manual only has Panoz specific PNs.

Thanks,

Brian

I used a 1" clutch master, it allows for a short travel and plenty of force!
