When you say 'redone' that is stock brakes rebuilt with new pads, seals and rotors skimmed correct?
Caliper rebuild kits are $30
Pads, probably $175 front or rear aftermarket
Turning rotors maybe $25 a rotor (good brake shops can turn the rotors on the car)
66 Mustang rotors can be substituted up front for around $175 a pair (slight opening of lug holes required) if yours are too worn to turn.
Even with tax & shipping that's less than $750 + labor.
For $3K you can get a nice aftermarket brake upgrade with calipers and rotors. Be aware that if you still run 15" wheels some calipers are too big, talk wit the vendors or it might become a $3K wheel upgrade too.
Good luck,
Julian
