Lost all braking power on 95 Max

Hello all, I just changed the rear pads on my 95 Max but lost all my braking power. The pedal is really soft and it seems like I have lost all compression. Can any one help?

I had the same problem on the front with my 1995 nissan maxima. Turns out I had air in the lines and it was a 2 person operation to bleed the air out. The pedal is still soft but it stops fine now. did you have any problem getting the piston back in the caliper?

If you didn't open the bleeders when you screwed the pistons back, it should just take a few pumps on the brake pedal to reseat them against the new pads. After that it should be OK. If not, check that the pin on the back of each pad went into the groove in the piston.

If you did open the bleeders, then you probably introduced some air into the system. Bleed them.
