HC Deb 17 December 1975 vol 902 c635W
Sir A. Meyer

asked the Secretary of State for the Environment whether he is satisfied that present regulations governing the materials used in braking systems provide adequate protection against a combination of corrosion and fracture; and whether he will stipulate that on heavy goods vehicles braking pipes should be constructed of metal tubing encased in plastic.

Dr. Gilbert

I have no evidence that the materials used in the construction of braking systems are generally unsatisfactory; but an EEC Directive on braking, the implementation of which I am currently discussing with the industry, includes a requirement for braking systems to be designed and constructed to resist corrosion and vibration.
