FERODO FABRIC FACTS—

The co-efficient of friction of Ferodo fabric is "4 constant
—this increases under speed, pressure and heat.

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.

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.
