Thanks for the facts Dave.
All to often people get caught up in opinions on this stuff without objective facts to support the clams. I have always thought drum brakes were better for all the reasons you stated.
The position that there won't be enough vacuum or they will fade and you won't be able to stop the car is non sense...do you really think Chevrolet made 327s, 348s and 409s that wouldn't stop in the 60s?
I suppose if you were burning rubber from light to light for 20 lights you might have a braking fade. I don't recall this being an issue back in the day. We always pealed out at lights, racing and I guess to everyones amazement we were able to stop, not on a dime but good enough for government work. I say people get caught in the scare tactics of those wanting to sell conversion kits.
Thanks again for making sense of non sense.
