2008 Lincoln MKZ with extensive brake pedal travel

I'm at a loss here..
This car has 55,000km on it
The dealer replaced the right rear caliper 2 month ago. When i got it back i noticed a difference in the brake pedal. It was not quite as firm as before but i did not take it back as it was not all that bad.
Last week, they replaced both front calipers.When i got it back, the brake pedal was spongy with excessive pedal travel before brakes start working. I do not get to the end but not far from it. My toe touches the metal arm, the pedal itself is mounted on.
Brakes where bled again, which resulted in a tiny bit of improvement but still have the excessive pedal travel problem.
Now they tell me that there is nothing wrong with the brakes.
( i do know that they did not use a machine to bleed brakes, as they just pinch the brake hose while working on brakes.?????
Apparently, according to the ford dealer this old way of bleeding is ok because no air gets into the ABS if they pinch the rubber brake hose.)
Point is that my brakes where just fine before caliper replacements. No new pads or rotors....just calipers been replaced.
Thank you for any and all replys.
Pete

A 2008! It needs proper brake bleeding by exact procedure I wouldn't have but dealer sure should! Just pinching off line on a fairly new vehicle? Not sure I like the idea for a brake hose at all as that will likely be a trouble spot later if not bubbled out now,

I sure am not fond of it either.
Dealer told me today that he can NOT find another ford dealer within 50 miles that has the brake bleeding machine.
So, i wonder how they get air out of the HCU (Hydraulic control unit) or ABS?
Not sure if that's the case with my car ( personally, i think it is)
Sure is real troubling that not every dealership has the machine/ laptop and software required to properly bleed brakes.
Just venting here.....
I hope somebody has the answer in this forum and is willing to share it with me. Dealer wont.......!

This info may help you. It applies to that car.
Pay close attention to the part about changing calipers. You shouldn't have to use a scan tool.
Your life would be a lot easier if you had a pressure bleeder though.

Hammer Time, Thank you for your great post
I have 2 questions
1.) Assuming they followed those instruction to the T, why would i end up with all that excessive pedal travel and not so hard pedal after caliper replacement that i did not have before?
2.) This is done under warranty, but if i was to buy a pressure bleeder for home use ( for future use after warranty expires ), which make and model of bleeder gives the best bang for the buck. I, so far have been driving fords only. Not sure if some bleeders are brand specific or not.
Thank you
Pete

There are varying sizes and styles of bleeders. They are a bit pricey for one time use. The bigger part of the expense is in the adapter package.
The vacuum type are cheaper but I don't think they will get the job done for you.
I have this one here and I use it quite often. It solves most bleeding issues.
