[Help] Brake fluid amount needed for a complete flush?

For an average pickup truck (F150, Ram 1500, etc) or average passenger car, how much new, sealed brake fluid should I have to flush the system? By flush I mean to drain the master cylinder reservoir and bleed each of the four tires until fresh fluid comes out of each.

Short of not having a pressure change setup, I do have the 1 wheel vac system but still not that easy. I can do it with 2qts most of the time less. I just run a tube at each wheel bleeder into a soda can (or equivalent repository), crack each bleeder and make sure master cylinder doesn't run dry. Can be done with 1 person all four wheels at the same time. **Caution** at no point press the brake pedal. It will gravity feed. Of course the front left will clear first and then the fr, rl, rr, so just close them as they clear.

Just a simple way I found to bleed brakes by myself. Also works when putting on new master cylinder or to try and find out if master cylinder is going bad.

If that is true, I'll need six 12 oz. containers of brake fluid (2 qts=64 oz)?!?

I have done most with a bit less than a quart. Empty master cyl, fill up, then vacuum bleed all 4 brakes. The fast bleed helps prevent the old fluid from mixing.

I never buy less than a quart, which is only $6.59+tax here. Time is money to me and calling someone in to pump the brakes when they could be doing something else makes no sense to me. Not to mention I can be doing other things around the shop while this is happening, I just have to check it every 5-10 mins.

**edit** the only thing I see in 12oz in synthetic $3.29 . And the only reason to run that in a brake system is for extreme towing or race applications.

I researched brake fluids, and it came down to Amsoil DOT 3 vs Valvoline Synthetic DOT 3 & 4. Both are quality fluids, but I ended up buying the Valvoline: »www.valvoline.com/products/brand···fluid/28

It's readily available and has great specs and a great price ($7.99+ tax for 32oz at Autozone). I bought two 32oz bottles and one 16oz bottle, and saved the receipt in case I'm way over.
