Keep bleeding you still have air in the lines.

 

i would bleed again and also try to spin the front wheel and be sure you did not accidently bend the rotor when changing the tire

 

would be odd that it happened to both at the same time , but wondering if the master cylenders could be going out? if brake fluid types were mixed ( maybe from a previos repair, the wrong fluid was used)

 

"We did the brake line furthest from the master cylinder then on to the closest one with no air."

There is a master cylinder for each wheel. Not like a car w/ 1 master cylinder.....

Try one of these should be all you need to do + the right brake fluid for the application

Bike brakes are very easy to bleed so something along the process may have been done wrong. ABS is a little trickier but still fairly easy.

 

NEVER put Teflon tape on bleeder fitting threads. There is a high risk of cracking the caliper housing as there is no room for a sealant on the threads. The nipples by the way to not seal at the threads. At the bottom of the nipple is a machined surface. It is what seats at the bottom of the bore and makes a seal. It is the same principle as AN fittings. It is a metal to metal seal. When the bleeder fitting is loosened, the fluid then comes up and enters the nipple through a hole on the side above the sealing surface. If you have a Bleeder fitting that weeps fluid, then it is because the seat inside is either dirty, corroded, or has been damaged from over tightening the fitting in the caliper.

The OP sounds as if two things are happening. 1) there is still air in the system, and 2) pistons are not moving freely.
Remove calipers, and clean around pistons with brake clean and an old tooth brush.

 

Good to know. I have never done it but read about people doing it here and thought of doing it.

 

A shoestring with brake kleen may work also with no tear down involved just zip tie the front or rear lever down before cleaning to clean pistons (Keep spray away from painted surfaces)

 

Hey notdrphildrmike, did you ever try cleaning the calipers real good. if so what did you discover? Now ya got me curious as to what the problem was.
