Should I drain the old fluid from my brake before bleeding?
Absolutely not. Draining the old brake fluid from your brake before starting the bleed process would be making an easy job a whole lot harder.
When you drain the old fluid from your brake system it is replaced with air and since the main reason for bleeding your brakes is to remove air filling it with air before you begin is the last thing you would want to do.
This is also true if your brake fluid is old and discoloured. Simply flush the system through with new oil until it starts to run clean via the exit port.
