§ Mr. Greville Jannerasked the Secretary of State for the Environment whether he will require standardisation of all roller brake testers so as to ensure uniformity of results, before authorising such brake roller testers to be used at testing stations; and, alternatively, whether he will require such changes to be made as may be necessary in order to ensure that testing stations are able to apply uniform standards in brake testing on such brake roller testers.
§ Dr. GilbertSince 1973 roller brake testers have not been acceptable as items of equipment in an MOT testing station unless they have met the technical standards laid down by the Department, whose engineers co-operate closely with manufacturers and garage associations concerning the performance and accuracy of this equipment. I am having investigated a report of discrepancies between measurements made on different types of roller brake tester, but my present information is that the current arrangements have ensured the consistency of the test results.
