I have a little B series Ic bus with hydraulic brakes . THe bus has onspots and nothing works . I can by pass the switch compressor runs but chains don't come down . Then the compressor will lock up because the air isn't releasing . Make sense does this setup have the same valve as the buses with air brakes ? Thanks
You can look up your parts breakdown on the On-Spot page. Do a quick Google search of "On Spot Chain parts" and you should find a page that is a pdf. You should be able to find all the components and figure out what part you are looking for to see if it is the same valve.
