Sir you must be extremely careful !! You have electronic brakes !! You cannot bleed the system without a pressure bleeder !

I am not satisfied to your answer.
Expert:  Lou P. master tech replied 1 year ago.

What do you mean !? The rear brakes are not used until the key is turned on. But you must use a pressure bleeder

Expert:  Lou P. master tech replied 1 year ago.

Why are you not satisfied this is the truth , if you get air in the system you will need a scan tool to bleed the system. When you pump the brakes you are not really pumping the brakes.

Expert:  Lou P. master tech replied 1 year ago.

You must understand this brake system is not like normal brakes.

Expert:  Lou P. master tech replied 1 year ago.

You are going to cost yourself lots of time and money if you do not follow instructions. You may not like my answer but it is the truth. You cannot use a vacuum bleeder. It will not work that is why you are not getting fluid.

Expert:  Lou P. master tech replied 1 year ago.

Ok I will opt out. I wish you luck but you need to trust my help.

Expert:  Lou P. master tech replied 1 year ago.

The pressure bleeder I bought was from snap-on. It was a blue point brand bleeder. I will upload a link for you. I apologize if I seemed rude I just don't want you to get hurt or damage your brakes.

Expert:  Lou P. master tech replied 1 year ago.

Expert:  Lou P. master tech replied 1 year ago.

Actually that bleeder comes with the adapter. Hope this information helps.
