New master cylinder and booster no brake pedal

I have a 2009 Tacoma 4x4 with the 4.0 v6 I've replaced the master cylinder booster rotors pads and calipers and I still don't have any break pressure and there's no aim in my lines anyone have any ideas as to my why breaks aren t work?

 

Did you adjust rear brakes?

 

After replacing all that I would say you might have air in them.

 

Sounds like air in the lines.

 

Did you bench bleed the master cylinder before installing it?

 

Do you have VSC?

 

What's vsc?

 

vehicle skid control

 

Yeah I have abs

 

Vsc is not ABS

 

I have traction control

 

When you turn the key to run, look for the letters VSC on the dash. ABS keeps the wheels from locking up during hard braking. Traction control limits wheel spin during hard acceleration. And VSC can apply brakes at individual corners of the vehicle if it starts to slide by using the ABS. You could also have air trapped in the ABS hydraulic control unit.

After re reading your original post, it sounds like you're saying you didn't have a brake pedal before you started replacing all those parts? I'd assume so since there's no reason to replace the master cylinder unless there was a problem. If that's the case, it's likely you have a dump valve that is stuck open in your ABS hydraulic unit.

If you had a pedal before, and you replaced both calipers, do you have them on the right sides? The bleeder has to be above the brake line that bolts to the caliper or you'll never get the air out. I've seen it a couple times.
