Bleeder valve won't close.

[NeedColoradoHelp]

Hey everyone we have a 04 Chevy Colorado and we had to replace a cailper on the passenger side and replace the bleeder valve on the driver's side. Now we are trying to bleed the brake's on the driver's side and the bleeder valve will not close. My husband tightened it and I pumped and brake fluid squirts out everywhere...Any idea's what would be causing this ?
Thanks~ Amanda

If whatever it took to remove the old bleeders damaged the sealing seat you would need to replace the caliper.Unless the new bleeders are china crapola and don't seat properly.
