Master cylinder with Disc/Disc brakes

I have a 68 with manual drum/drum brakes that I'm installing a Versailles rear and Granada front disc brakes on. Is there a master cylinder for manual brakes that I can use that is for disc/disc. I don't want to change out the pedal or buy a booster if I don't have to. Besides I like manual brakes better.

Im using a manual master cylinder from a 84-86 mustang svo. I found a new bendix unit on ebay for $25. Aluminum with a 1.125" bore. Stiff pedal, but it works well for my taste.

That is the exact brake setup that was stock on a Versailles. I'd use a Versailles MC, as the larger bore of the SVO unit is just making it hard on your leg, and the SVO was designed for larger brakes.

on my falcon i just upgraded to 4 wheel disk and i used a 77 granada with power disk up front and drums in the rear it works nice i think its a 15/16 bore and it seems to be working fine for me

I used the SVO unit and it works fine on my setup...

MasterPowerBrakes sells a large bore, dual chamber master cylinder that's designed just for early Mustang 4-wheel disc, non-booster conversions. It just bolts to the firewall and uses the original pushrod. I used a '77 Lincoln Ver-Sigh donor...it takes extra pressure but works and looks great.

I have a mastercylinder that would work perfect for sale. I use the same MC on my Mustang, but I managed to buy an extra one at some point, so I'm selling this one.

I have 4 wheel disk brakes with an original drum brake master cyl although I removed the combination valve. Works fine

Wilwood aluminum dual resevoir 1 1/8th bore here, I have Granada fronts and wilwood rear discs. Summit prop valve on the rears. The pedal is firm, but with excellent feel.

Back in 1989, I put a SS brake kit on my '65 coupe. The kit had the 4 piston calipers in the front and single piston T-bird calipers for the rear, but no master cylinder came. I bought, if I remember right, a'67 dual reservoir front disc rear drum master cylinder for $25 from a place like NAPA. To make it 4-wheel disc compatible, I removed the inner residual pressure cone from the front port (rear brake reservoir). It worked fine, I didn't use a power booster either. I did have an adjustable proportioning valve that I plumbed next to the drivers seat so I could adjust the pressure while driving (only had to make 2 adjustments from rear lock up and it was set). I had been told this trick by someone in the brake industry, but can't remember who. Verify this before you try it by asking someone who knows mastercylinders. Some guys discourage this so they can sell you a new more expensive one.
