Brakes may apply without warning: Processing bores of the manually operated brake valves have been closed using balls, but in somecases, the balls have not secured properly in the housing and may work loose. Then the valves may bleed air and activate the parking brake or anti-jack knife brake. Recall the vehicles likely to be affected to check if an affected valve is fitted. For affected valves check the crimping is correct and fit caps to the valves where the crimping is not correct. Affected existing spare parts stock is to be returned. The vehicles supplied with new valves must also be checked and fitted with caps as necessary.
