4 wheel discs
 

I plan on doing the front disc conversion this week, and also am going to put disc on the rear, what kind of manual master cylinder will work for a 4 wheel disc set up and is a proportioning valve also needed. All I can find is manual master cylinders with disc/drum set up for manual brakes....thanks in advance for any info.......C898:confused:

I use a standard 68 master cyl. for disc/drum. I installed a manual proportioning valve in rear brakes. You remove the residual valve from the rear fitting in the master cyl.

I have heard that you can also use a SVO master cyl. They had 4-wheel disc. You need a one inch bore master cyl.
