FERODO FABRIC FACTS

Invented 20 years ago, Ferodo Fabrics are to-day as
superior to other friction surfaces as they were in
those days to the “ makeshifts ” they displaced.

Ferodo fabric absorbs more lbs. of energy per
sq. in. than any other brake or clutch lining.

It permits of maximum acceleration and deceleration.

It gives rapid dissipation of heat.

It is three times more durable than chilled iron—
five times more durable than leather.

It cannot carbonise, cannot slip nor seize, cannot
spark, cannot throw off metal dust.

It gives equally effective service when first fitted and
when worn to the thickness of a piece of paper.

List

Ferodo fabric has been exclusively used for many years
by the London and Paris Underground Railways.

It stops the London Underground trains, travelling at thirty
miles an hour, in five seconds without jerk or noise.

On the London Omnibuses the average life of the Ferodo
brake lining is 50,000 miles.

It is used on cranes and winches, winders and haulages,
hoists and friction drives, clutches for every purpose, on
every duty where an efficient friction surface is essential.

It is thoroughly tested in our laboratories before sending out.

It is stamped with the name “Ferodo fabric” to guard
against substitution. All imitations have been proved
by independent tests to be inferior. Insist on genuine
Ferodo fabric for brake and clutch linings.
