You have bad cad calipers. Replace them

Your alarm sytem went off because it thinks you disonected the batteries to steel the truck, ect, call a ford house,i hate these new computerized cars, were stuck with them, check you owners manueal, Matt

Ford has special bleeding and blocking instructions for clutch slave. Check manual for proper bleeding requirements. May consider presurre bleeding of master cylinder or use master cyclinder bleeding tubes that fill the resevoir as you bleed the and remove all air in system.

OK, did you bench bleed the master cylinder before installing? If not, the warranty will be void, and the pedal will drop even if the rest of the hydraulic system is sealed.
I would try another new master cylinder if the bench bleeding was not performed and the master cylinder was deemed to be damaged.

If the master cylinder was bench bled, and it does this, maybe you can get it replaced with a new one under warranty.

Good luck on this repair.

When you say it pulls to the left, I am assuming only when the brakes are applied. And if the pull problem was there before you replaced the calipers, it is a problem like a plugged primary brake line from the master cylinder or proportioning valve. The master cylinder could be bad. The new right caliper could be bad. Need to disconnect hoses closer to master cylinder and hit brakes to see if fluid flows good. Then follow hoses down and repeat.

If this happened after the new pads were put on sometimes the pad length is different on the inner and outer pad and both longs on one side will grip more than the 2 short pads on the other side.

If this pulls without brakes on you may have stuck left 4x4.

Did you bench bleed the master cylinder? If not it probably has so much air in it, the piston on the master cylinder may have bottomed out in the bore. You may have to remove and do it over.

Adjust your rear brake shoes. Then rebleed the system. Start at the master cylinder Bleed master first then the wheel furthest away from the master (right rear then left rear then right front then left front. Do that and your pedal should be good.

i had a problem with my abs light one night i had a brake line behind the driver front tire broke and it was leaking out all of the fluid and the abs light came on i replaced the line and filled up the master cylinder and it went away so check your lines and master cylinder
