Wow! I don't know where you live, but here you can get front and rear brakes installed for around 175 to 200.00. I get the pad for around 15 bucks with a lifetime warranty.
As far as the calipers, I find it hard to believe he couldn't compress the pistons. I wonder if it tried opening the bleeder to see it that helped. That is the proper way to do it so the old fluid comes out and there is no chance of damage to the master cylender. Also, if the rubber brake hose to the caliper is deteriated inside, I've seen situations where fluid would pass one way and not the other. Opening the bleeder would have answered that question.
As far as the low brake pedal. If the caliper didn't move, the front brakes shold still be where they were before. If I had to guess, I would say the rear brakes are out of adjustment. Are you able to pump them up when driving? In other words, if you pump the brakes, does the pedal get better or remain the same?
As far as the pads seating, that is a joke. When they installed, once you pump the brakes a few times, the caliper pistons come out to where they need to be and compress the pads into the rotor. No more adjustment or seating is necessary. The rears are another issue. With the vehicle off the ground, the brake shoes need to be adjusted until they touch the drum and create a drag. Once that happens, one should pump the brake pedal several times to center the shoes and then readjust until there is a slight drag on the wheel.
All I can say is this, you paid (a lot) for the brakes to be repaired, and now they are worse. Take it back. Or if you can and would like to see if you can get them to work better, let me know and I'll explaine what to do. It will be more work at home, but that is up to you.
I still can't believe it, 610.00 for a brake job. I'm in the right profession but the wrong state.
Let me know what you decide.
