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 put it all together and try hitting the brake pedal? Bleeding the system?

 

they should push the piston out as soon as you hit the brakes...you may have a bad caliper. is it a new or rebuilt one?
ive got to replace the backs on mine..the pads are dragging.

 

You replaced the caliper & pads, now when you push the pedal the piston doesn't come out, correct? First thing, just leave the bleeder open and let the fluid run out ... (gravity bleed it). . Close the bleeder and try it, any improvement? If not, do you have any kind of a brake pedal? I'm not sure what you meant by "broken caliper"? If it was sucking air you might have to bleed all 4 corners, especially if the master cylinder ever got empty Might be you killed the master cylinder when you just jammed the pedal to the floor. There's the areas your seals run in and beyond it with age and corrosion you may've ripped them. When you buy a new master cylinder you have to bench bleed it before putting on the truck and there's a warning not to depress the piston fully, they're not kidding. (trashed a new one like that once)
