MET AI creates sparks and gives a very spasmodic brake action. Spoils your brake path and gives an unreliable
lilt I AL brake-power.

lAFAflll creates sparks, smokes, burns, and is thus a constant danger for everybody. Wood wears quickly and you
VVUUU cannot depend on its brake power, because oil, water, grease, or any other liquid affects its co-efficient of
friction noticeably. In most cases you have to use reverse steam.

fabric is absolutely spark-proof, it doubles your brake-power, no need to use
reverse steam. It lasts many times longer than wood or metal. Ferodo fabric
is cheaper in the end. Your men have confidence in your brake, wind faster
and you get more coal every hour of the day. Eerodo fabrics engage sweetly,
they save ropes and machinery. They give instant power and keep the drum
path always smooth and unworn.
