§ Mr. Greville Jannerasked the Secretary of State for the Environment how much he estimates brake tubing corrosion costs the United Kingdom economy per annum.
§ Mr. MarksThe replacement of corroded steel brake pipes is estimated to cost about £15 million a year. The use of corrosion resistant non-ferrous alloy tubes which would effectively solve this problem would add up to £10 million a year to manufacturers' costs. From the point of view of safety the performance of steel brake pipes gives no cause for concern.
