On Monday the 15th of September, LHM Fuel Truck #06 brake failure while traveling down the ramp at A-2 pit. Mr Prapad felt the brakes were starting to have very little effect and the truck speed started to increase. He then pulled on hand brake but can not slow truck down. He continued down the ramp and up the adjoining ramp to the -10RL where the truck came to a momentary stop. The truck then started to roll backwards he turned the steering wheel right hand down and the truck came to a stop when the high wall was contacted.
