How much brake fluid do you need to bleed the whole brake system? Thanx.

 

brake fluid is cheap, like what, $3? buy the larger of the two containers - that way if you use up one of the smaller ones, you dont have to go back to buy more fluid, half of that should be enough if you're bleeding the whole system out.

as for brand, as long as you don't buy the "store" brand, then it's fine. even the store brand is fine... up to you.
