Hello Tom - 

MR>> I wonder why they still use drum brakes in the rear
MR>> wheeltrain when disk brakes are so much simpler and
MR>> effective. Okay they fade more when wet or hot but not
MR>> that much. It can't be cost alone, by now the cost of
MR>> either system is about the same expense. 

TW> It is cost. It is small but Drum brakes are still cheaper.
TW> One might say but how Much. Well in most industries having

TW> unit can be significant. And if it is a fairly high volume
TW> production item even less then a Dollar is significant. 

I was told that people who managed contracts for Chrysler would
dump a supplier with a 20 year history with the company for a
new one that was $.05 cheaper per part. :-) 

Another problem - I remember when european cars had stickers on
them warning "Four Wheel Disk Brakes" to try to stop people
from running into them when they panic stopped.
