§ Sir A. Meyerasked 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. GilbertI 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.
