Normal braking is OK, but when you need to stop quickly and you press down hard on the brakes it feel like stopping on ice with the ABS on and you don't stop quickly.

Front brakes look ok replaced rear caliper and it improved slightly.
Do you

Is there an abs light on? If so it will need to be scanned, in order to find out. If I were to take an educated guess, I would suspect. That is the abs pulsing so that it doesnt skid, it pulsates so fast, gripping the rotor then letting go thousands of times during an immediate stop, so that it wont skid or lock up, it will never stop on a dime when using abs, because that can potentially cause a skid.

It doesn't make the grinding sound of ABS. No ABS light. Just at highways speed the brakes work poorly.
