<VV> LM brake questions

[Sadek Charles H DLVA]

A partial response.

Properly rebuilt as req'd and maintained drum brakes will be fine.  The
factory size MC and wheel cylinders are correct for the application.  They
will stop as well as any street disk brake car other than the great big high
performance disk brake sports cars, etc.  

For legal speeds, drum brakes should be very suitable.

Above 100 mph, under controlled very severe braking as done on track, the
drum brakes can brake with the disk brakes in competition applications.
However, it is difficult to get everything exactly right for that threshold
braking situation. Slightly reducing pedal pressure will result in
controlled braking but longer stopping distances-in the instance I am
talking about.  In other words, at 120 mph at the end of the straight in
#73, the brakes have to be RIGHT ON to brake at the limit.  If not, you have
to ease off, which results in slower lapping times.

This sensitivity to minor imperfections in the set up is not there on disk
brakes.

Rears are actually more important because, due to the bias of weight toward
the rear of the car, they do most of the work.  Actually, the factory drum
brakes are pretty good.  I would suggest you post to FastVairs and ask how
many of the serious race guys are running 4 wheel disc.  Certainly would
look cooler, but I am not sure that that would be your best use of money.
Also, there are two kits from Clarks for the front, and if you go that way,
from what I understand you don't want the cheap set.
