cruiseliner64 Posted 1 hour ago Share Posted 1 hour ago Hi guys,The parking brake on the Cruiseliner wont release.Iv checked and rechecked that I have any pipe work that was moved during painting connected properly(took loads of pics as well as marking them)What I have found is Iv no air at all up at the parking brake control valve on the dash.Im wondering where the valve is fed from or any other ideas you might have.....

Geoff Weeks Posted 1 hour ago Share Posted 1 hour ago Do both air tanks (primary and secondary) have pressure? Quote Link to comment https://www.bigmacktrucks.com/topic/76244-more-air-problems/#findComment-587368 Share on other sites More sharing options...
Geoff Weeks Posted 1 hour ago Share Posted 1 hour ago What type of valving does the truck have, a multi function valve with both red and yellow knobs or individual buttons ?

cruiseliner64 Posted 54 minutes ago Author Share Posted 54 minutes ago Yes all tanks have full pressure but the parking brake is a europian type lever with 3 pipes.As I remember one is a supply pipe and should have air at all tines the other pipes direct that air to valves to release or apply the parking brake depending on lever position.I was wondering where that air is supplied to the lever comes from.The pipes are not colour coded and will require a lot of work to follow them but if I have to I will do it.The dash would need to be partly removed a job Id rather not do this side of Christmas.

Geoff Weeks Posted 50 minutes ago Share Posted 50 minutes ago Ahh, well I don't have a clue on how it is done over there. The British buses used a mechanical hand brake and the Austrian were similar to the US in having a button that pops out on loss of pressure.
