New Brake Calipers Locking Up!

Hey guys, just put both new front calipers on my 89 Firebird Formula as the driver side was pulling and the passenger was "locking up". Even after I replaced these, it is still continuing to do this as if I replaced nothing any ideas on what could be causing this? Passenger side only locks up temporarily, and then releases after a while, and the driver side is still pulling like hell. Maybe lines are shot? any input is appreciated. Thanks

Hey, Eric,

The rubber lines are 20+ years old. While they may look fine on the exterior, they've no doubt collapsed on the inside, thus creating a check valve of sorts. Replace them all.
