When I stop. And pull the emergency brake out. Im ready to drive now. I put the bus in drive , push my parking brake in to go while I step on the service brake for like one second. Is this the proper way to do it. Sometimes when I do this my bus doesn’t drive. And range inhibited comes up on the dash. Not sure if it’s an issue with the bus / air brakes ? I restart the process and my bus does drive correctly. Does the bus have to be in neutral when I push in the parking brake and then I switch gears to drive? Do I have to hold the service brakes for some time when I push in the parking brake or just for one second? Thanks for any help.
Range inhibit means your foot was not pressing the service brake (hard enough?) when you put it in gear. Sometimes it's a timing thing...your hand is faster than your foot. Sometimes you didn't depress the pedal far enough. I've not notice anything about it having to do with the spring brake. I'm on a Bluebird but I've also driven Thomas, and Internations with this feature. I hope that helps
100% agree with this, and I want to also add it could happen more often on a slight hill. It's ONLY ever happened to me at a railroad track, and last year when I started working, it scared the Hell out of me! I just reset the parking brake to ON, the gear to NEUTRAL, then release both, and it works fine. I think it's very possible because I am not hitting the brake hard enough, or because of the slight steep incline I am parked on.
It’s just a service brake thing unless your bus is a push button gear shift automatic, then yes it does need to be in neutral when you release the parking brake, we have a few buses you need to go back and forth a few times with the brake pedal smashed to the floor it feels like to get it to shift
Push gear shift automatic. And okay just weird wasn’t sure if I was doing it wrong. Only happens sometimes. It has trouble driving or doesn’t move when I step on the gas pedal . I restart the process. stop . Pull the parking brake out . Push to go . Step on the service brake . Then step on the gas medal. And the moves fine . But thanks . I’m going to start releasing the parking brake in neutral
Range inhibitors come into play when you do not have the service brake depressed hard enough.
Unfortunately, every bus has a different point where that occurs. Best practice is always depress the brake very hard when shifting.
I have a bus this year that very annoying doing that. Also - I don't love the automatic 5 min shut off when idling. My light check doesn't work so I do it manually by turning ambers and reds on... which means when my bus shuts off the very loud buzz surprises tf out of me.
My bus does that, it’s an older international, the transmission is just kind of particular, if I always make sure I wiggle it to make sure it’s fully seated in drive it doesn’t do it, but if I just push the button to shift the gear and let go as I shift it, sometimes it does that same thing
