Default Brake help.

I know brakes are suppose to be easy as pie, but I'm having issues with a new front brake system install. My pedal is super squishy.

Swapped the calipers, pads, and rotors today with a buddy of mine. I'm sure we did everything correctly.

1) Removed the brake line via banjo bolt, and hung.
2) Removed holding pins and caliper.
3) Removed rotors/cleaner preserves off new rotors.
4) Bled passenger side, then driver side.
5) Topped off brake fluid with DOT4.

Install in reverse order. Both of the copper gaskets are in the correct locations, on either side of the brake line adapter, through banjo bolt. I know squishy brakes mean air in the lines, but I don't see how it's getting in. My only guess is that I didn't wire brush the corrosion off the brake line adapter so it's not sealing properly. Or does the banjo bolt need to be a a certain orientation?

Now I wasn't the guy manning the bleeder valve, so I'm not sure if all the air was bled out. Though we did the 3 pump, open/close method. I lost my helper, so I'll have to go back to it tomorrow.

Any thoughts? Did I miss a step?

Did you put the calipers on the correct sides?

Bleeders should be up top.

Okay, had to ask since it's a common mistake.

I'd suggest bleeding the entire brake system.
Pass. Rear, Drivers Rear, Pass. Front, Driver Front.

and if it's still squishy then i'd start looking towards the master.

You bleeding the brakes with a bottle half filled with brake fluid and a hose attached to it?

If it wasn't squishy before then probably not.

Take it one step at a time.
Bleed the system and let's go from there.

Just a hose attached to it. Though I've done it with just news paper under the wheel and it's been fine... Maybe I should jerry rig up a bleeder bottle.

Also, I did not do the whole system. Following the Haynes Manual, if the rears weren't touched, they're not necessary. I will do the whole system this time.

Not sure if it's my MC. Definitely more squishy than they were before. I was having bad breaking due to a stuck caliper on the passenger side. The inner pad was worn down past the slot, though every other pad was like new.

The brakes will grab about 1/4 of the travel length in the brake pedal. They're just REALLY spongy. Like there's not enough pressure behind the pedal.

I guess that's a good way of putting it. Not enough pressure is being delivered to the brakes. Thus, the pedal is spongy.
