Thank you Masseyman for the quick response. It does have drum brakes on the back. I will readjust them again but I won't get to them until Wednesday.

Are you sure you put the correct calipers on the correct sides? The bleeder screws need to be up top pointing up.

I replaced the master cylinder and the calipers on my truck. I bench bled the MC a very long time to get all of the air out. Then I gravity bled the calipers with a plastic tube connected to the bleed valves and then sticking through the top of a jar. After the end of the plastic tube was under the fluid it couldn't suck air back in even if i pumped the pedal. I bled my truck's brake system by myself!!!

Thanks GLC, yes I made sure the correct calipers are on the correct side.

Roadie, that was another thing I planned to try. Allow gravity to bleed out the system. Thank you for the idea.

I have bled all 4 lines 3 times and continue to have a mushy pedal.

Any thoughts??
Is the bleed screw on the top or the bottom of the calipers you installed???

The bleed screws are on top as they are supposed to be as were the original ones I removed.
Thanks

oops - I somehow missed that the first time... I think I never read page 2?

This is a common mistake though - I've even seen a technician do this at a big 3 headquarters. (I won't name them, but it wasn't Ford)

You probably just have some air lingering in the system. Keep bleeding.
Use care not to "bounce" the pedal against the floor. This can suck a small amount of air back in and make it harder to bleed.

I've had this problem before on a Contour. If the rear brake shoes are not adjusted so that they are close to the drum, the pedal will be mushy.
