No, it isn't specific to ABS brakes. However, it will make the brake harder to push. As far as the booster, it is the large round thing that the master cylender bolts to. It will feel like it restricts the brakes if it isn't working properly. However, it won't cause the brakes to hang up or stick on. I've never seen a master cylender do that either.
The vibration is most likely warped rotors. If they are warped badly enough, they may be making contact with the brake pads causing them to heat up. Also, when you replaced the brake hoses, are you sure the slides on the calipers are releasing as well as the caliper pistons?
