Mush Mush on brake pedal

I have a 2015 taco 4 x4, it has front disc brakes and regular drum on rear. I have had the sys bleed, I also changes the front disc's and new ceramic pads and I still have a pedal that goes to the floor and very mushy. I just ordered SS Brake lines and hope that this makes a difference.

Other than changing the master cylinder which I think is ok, is there a double master or something better than the factory one?

Any suggestions I will take!

Thx's

 

How did you have the brakes bled? Some models need the brakes bled via computer (TIS Techstream).

 

the first time I did it in my driveway the conventional way, then a month later I had a mechanic do it in his shop and this guy is a certified Toyota ex mechanic of 20 years. He did it with some kind of vac pump sys? This was the way to it correctly so he said.

 

Try adjusting the rear brakes.

 

Bleeding the brakes with ABS can be tricky. When did you start having mushy brakes. Did you open the brake line system at some point? Certainly sounds like air in the system.
