Winding Engines fitted with
Ferodo-lined Brakes

possess a 50 °/o greater margin of safety and can be
worked at higher speeds than those fitted with the old
makeshift materials such as wood, leather and hemp.

These relics of an inefficient age have all the short-
comings common to makeshifts. They are adversely
affected by pressure, speed and heat.

Ferodo fabrics give a higher co-efficient of friction, which
enables engineers to raise their standard of production.
