[BMWCSRegistry] Re: General Brake Question -- BMW, not E9

[Gary Siepser]

So my addition is in line with Andres's.  Years ago, like about 30 
something of 'em, I was privileged to drive a neighbors Ferrari when I 
was still the proud owner of a Fiat 124.  To demonstrate what a smart 
driver I was, I down shifted on the way to a stop sign.  Frank looked at 
me and asked, "Do you always do that?"  I replied in the best know it 
all young driver  tone, "Of course, that way I save the breaks."  Frank 
gave me the withering look of a United 747 captain and winner of many a 
race and asked, "which is less expensive to replace, break pads or 
clutch plates and gear boxes?"  As Andres said, break first then shift.
