SAFE BRAKES FOR PASSENGER CARS 530256

THE bonded bimetallic brake drum has been developed to help solve the increasingly difficult problem of providing satisfactory braking service for modern cars.
These drums have an aluminum-alloy housing bonded to a cast-iron liner.
In this combination, the cast iron provides the wearing surface and the aluminum alloy provides the high heat conductivity and low weight. The result is an improvement in the rate at which heat is dissipated and a lower unsprung weight for the car. These brake drums have also been found to help considerably in eliminating squeal.
In England, it is reported, several car manufacturers are already using these drums successfully.
