Nathanwhit1 Posted Tuesday at 09:42 PM Share Posted Tuesday at 09:42 PM Evening all my mate has an ultra liner and struggling with the handbrake. The truck is building up too full pressure but the hand brake won’t release. We think there’s a valve sticking what’s stopping the air tank filling as the air suspension won’t inflate either. Does anyone know the location of the valve or which air tank feeds the hand brake system and suspension system. cheers Nathan Quote Link to comment https://www.bigmacktrucks.com/topic/75090-v8-ultraliner-m-h-613-hand-brake-fault/ Share on other sites More sharing options...
D-Day Posted Tuesday at 11:16 PM Share Posted Tuesday at 11:16 PM Make sure all air tanks are drained I have found some so full of oil and water nothing would work also some air tanks are divided vertically so both ends need drained Quote Link to comment https://www.bigmacktrucks.com/topic/75090-v8-ultraliner-m-h-613-hand-brake-fault/#findComment-568045 Share on other sites More sharing options...
