I have had cars with 4 wheel drums that stop great and others that didnt.I dont know why some did and didnt stop well.Now the ones with good brakes would start to fade/heat soak after stop light to stop light racing after about 10 -12 lights of jamming the brakes to stop in time to race again.This was many years ago.But on another note my 99 dakota has 33 inch tires on it and they would also heat soak the front discs.I upgraded to drilled and slotted rotors and they never get hot now.
