There's nothing more I can add I have no back brakes I'm trying to bleed. Them
Expert:  Lou P. master tech replied 4 months ago.

ok so how are you trying to bleed the back brakes? because you need a pressure bleeder to bleed them, if you are pumping the brake pedal you are not pumping anything your car has electronic brakes. all you are pumping is a spring and pressure to the front brakes.

Request lou pI understand my rear brakes are electric but they also hydraulic.But you still have not answered as to what the problem could beThis happened after the accident
Expert:  Lou P. master tech replied 4 months ago.

I did sir, you will NOT get any fluid our of the rear unless you use a pressure bleeder, when you pump the brakes you are NOT pumping real brakes especially in the rear. you need to use a pressure bleeder that can produce 2 bar (28 psi) . also if you did not loosen any lines or lose fluid there is no reason to bleed.
