I have ffr 33 hot rod kit completely built with the ff front suspension and duel piston calipers on front that came with the kit. I'm running a 94 mustang 8.8 rear end with single piston calipers. The brake pads & the rear rotors are after market non vented. The system is total bled out. The brake pedal is nice & hard. First time out for a road test the car would take the length of a football field to stop at around 40 mph slowing down gradually. I understand that the car has no power brakes and I understand that the brake pad and rotors have to brake in. But I have put 20 miles on these pads and rotors and they're still reacting the same. Before I spend the money to go Brembo brakes. If anyone has had this problem and has corrected it or has any suggestions please email me . Thank you
