Disk/disk brake question

After doing a extensive search I still have to ask. I have a 48 Chevy coupe with a M/2 front suspension and a Ford 8.8 disk rear end and I am looking for a bone yard firewall mount booster and master cylinder that will work. I plan on using an adjustable proportioning valve for the rear brakes so I don't think I will need a combination valve, true or false. What master cylinders will work on this disk/disk system and what pedal mount has been used in this application.

Thanks, Dan

 

Have 70s corvette M/C Dic/Dic.

 

i would ttend to think the one used on the expiorer the rearend came out of it should be metered right for tjis combo. tom

 

You don't want anything other than a proportioning valve on 4 wheel disks and you may not need that if you get lucky on the piston area, weight distribution and tire sizes. Test it on wet road with a panic stop.

Don’t go bigger than a 1" bore MC unless you have at least 6-1 pedal ratio. I like 7/8" MC bore size for manual disk brakes with a 6-1 pedal ratio.​

I would never use a boneyard MC, ever...​

I intend to use a new master cylinder, probably a Corvette style. But what would be the best firewall mount swinging pedal to adapt to the 48 Chev. with this type of master, Someone must have a preference. I could buy a universal pedal assembly but I'm to cheap, lol.

 

The nice people at Pirate Jacks have always helped me. I usually get a smaller bore MC than usual so I can lock the brakes up if I need to. It, of course depends on the size of your rotors and tires too.
The combo valves have a delay built into them that the adjustables don't. Just put more drop into the adjustable. Remember the fronts do 80% of the braking.

Your original question is a very tough one. One hard to recommend parts for, but you can always change cylinder sizes to compensate. The aftermarket Corvette MC's are hard to beat. Good luck
