IML: AW: AAJ vs stock brakes for 1957

["dietmar frensemeyer" <stadtapoachern@xxxxxxxxxxx>]

My son has a business, that offers big brake upgrade to fast and heavy cars.
I had any possibility to change the brakes of my 1960  Imperial to disk
brakes.
I don?t. 
Driving the Imp in a moderate manner and  caring about the huge drum brakes
is sufficient.
I?m not convinced that a disk system fitting to 14 ? or 15? wheels   will
improve braking power. 
Disks are more easy to maintain  and the knowledge to  maintain and adjust
drum brakes has become rare. 
I read many offers in the US market saying: ?easy to install?, ?one hour
job?, ?life time warranty? ? I?m not convinced that this is the truth.

I have to agree with Kenyon - NEVER lick the brake dust from your wheels.
 That said, well-maintained stock drum Imperial brakes work pretty darn
well.  I can say that they even tolerate a fair level of hard use, judging
from their performance in my 61 softtop (coast-to-coast road rally, 4,000
not-exactly-gentle miles in two weeks, summer of '06).  Given the modest
mileage on yours, I'd say replace the rubber and ride!

Now here's a question - given the relative simplicity of disc brakes, how is
it that the remarkably complicated drum brake systems ever became standard.
 One argument is that they are self-energizing; a useful trait before
reliable power boost; but that hardly explains why they lingered on for
decades after power brakes were introduced.  That they stayed on cheaper
models longer suggests they're cheaper to make, but just looking at the
parts count and total mass of the two systems, that seems impossible.  Any
ideas why discs didn't own the world earlier?
