I have a 2000 chevy blazer 4WD, having someone reliable replace the brake pads and caliper for me on the front driver's side. The caliper had broke and so the abs light was on when we went to fix it. We can't get the piston's inside the caliper to pop out, is there some secret to this? We poured brake fluid into the caliper and the reservoir where the brake fluid is held is full, we still cannot get them to come out so is it something to do with the abs system? I tried taking out the fuse that is for abs and we tried disconnecting the battery to get the abs system to reset but no luck getting the pistons in the new caliper to come out. Please need help, very frustrated!!!!

 

did you bleed the brakes yet, you may have ton of air in there from swapping out a caliper.
