HC Deb 08 December 1981 vol 14 c379W
Mr. Skeet

asked the Secretary of State for Transport whether he is satisfied that there is available a material other than asbestos which is wholly satisfactory for brake linings incorporated in drum and disc braking systems.

Mr. Kenneth Clarke

No. I am not aware of any asbestos-free friction material with all the characteristics necessary to ensure efficient and safe braking of road vehicles generally. Blue asbestos is not used in brake linings.
