How many litres of brake fluid do I need?

#1

I’m having my alignment done in a few days and since I had bleeding brakes I’m going to have them flush the system with ATE Super Blue while they’re at it. I have 3L that I’m going to supply but I’m wondering if that’s enough.

3L is more than enough.

#3

Whole system holds a bit shy of 2 liters iirc.

#4

1L of fluid is more than enough for a full flush. Bleed a measured 350cc from one rear wheel and 150cc from each of the other three wheels.
