Hot Rods Can I convert a Corvette (aftermarket) master cylinder...

... from a Disc/Drum to Disc/Disc? I had read somewhere that the only difference is a valve that you either add or remove.

Any info would be appreciated.

 

The after market Corvette type MC I'm using on my latest project did not have residual valves installed. I'm using it on a disc/disc application. I added two pound residual valves front and rear.

Just go buy a 68-72 vette master which was disc/disc. Can get a power or non-power unit. Been using them since the 70's.

 

Just got a reply from CPP and fellow says the master cylinder I have can be used for both disc/drum and disc/disc. So I'll used "DoublePumper's" advice and install external residual valves front and rear as well as proportioning valve at the rear.

Thanks to all who replied.

 

The main concern is having enough fluid reserve in the master for the increased fluid volume of disc brake calipers over drum brake wheel cylinders. You're good to go....good luck!
