§ Dr. David Clark
To ask the Secretary of State for Defence on what date his Department withdrew from service the RB44 Army light vehicle; and on what date his Department was first alerted to the problems with braking mechanisms of the RB44. 
§ Mr. Arbuthnot
The issue of braking first arose during trials in 1989, but the shortcomings were addressed before the production contract was placed in 1990.
The vehicles were temporarily withdrawn from service in June 1992 following problems with braking performance reported by the Royal School of Artillery in May 1992; after modifications, they were restored to service in November 1992. Following the results of further testing under stringent conditions in August 1993, the vehicles were withdrawn from service in December 1993, but were accepted again for service in August 1995.
