Re: 73 brake booster master cylinder on a 69 c10

Welcome! Is your 69 4 wheel drum as original, or is it a disc/drum conversion? Are you running a power brake booster on the 69 or not?

4 wheel drum brakes don't require a proportioning valve. You should look into bore size on the 73 MC if you are NOT running a booster as different piston sizes will change brake pedal effort and feel.

It's original 4 wheel drum and I put the disc in front ..
I still have the factory lines and going to put a booster and master cylinder from a 73 c10 so it's now going to be disc drum I was just going to buy a proportion valve from a 72 so it can mount on the fire wall
