I Took my BF2 front callipers off the car at 1500Km (new) and upgraded the braking system. I have just rebuilt the car and moved every thing over to a new bare body shell and refitted the factory BF2 Discs and callipers. At first start up and brake peddle test the front brakes locked on and won't release even after the car was turned off, it is almost as if the brake pistons have seized (while they were off the car the were well stored with no moisture). I am wondering if this could be an ABS issue? Would re-flashing the computer and downloading the factory software be the answer? I would apreciate any suggestions.
