Bedford air over hydraulic brakes.

Would anybody have an exploded view of a Westinghouse hand brake controller for a 1979 TK Bedford. Also does anyone know what air pressure the system should run at. It is air over hydraulic brakes with spring park brake. Many thanks.

Thanks JonD, Could you please tell me what the title of that book is. I have plenty of Bedford manuals but none that cover this system. My valve looks exactly the same but we cannot get it to release the spring brake. We can only release it by the emergency lever. Many thanks for your help .Kevin.

It's the Service and Training Manual.

I once found an online copy but can't find it again. The manaul coveres all sorts of Bedford brake systems.

Might not be the lever but the change over valve???

Thank you very much for all your help. We should be able to get somewhere now. Kevin.

Kevin,

you're welcome. There are a number of different circuits. I thought this was the best fit based on the thread content.
