Re: ‘69 c10 Brake master reservoir layout

To reinforce what was recommended above:

1. Get a M/C for a 71-72 C10. It will have a larger front reservoir which feeds the front disc calipers via 3/16" line. It will also have a 1-1/8" bore, whereas the 69 M/C has a 1" bore.

2. The proportioning valve should be in series with the rear brake line, which is 1/4". Crack it wide open to start, and don't adjust it unless the rears lock up before the fronts during a panic stop.

3. If you already have a 3/16" rear line, I'd probably go with it. Square body trucks had 3/16" front and rear, at least that was true for my 82 C10.
