I cannot find brake switch. Lights are not working. I checked fuse box and fuses are good.
air brakes, or hydraulic?
In my 8100 international, the brake switch is on the back wall of the cab, kinda behind the drivers seat down by the floor.
Same place in my 2375s, but they almost the same truck. His is probably a straight truck.
Air Brales
I'll check there
my truck is a bucket truck
I think the switch behind the seat is a tractor thing, so if you don't see it there, look all around the treadle (foot brake) valve which is under the dash if yourpedal hinges from the top. I have also seen them on the outside of the firewall, under the hood.
Forward side of bulkhead. 2 spade switch in a push lock fitting Td into an airline.
Should be 2. One for brake lights and one for cruise disable.
Hi funwithfuel. Not familiar with bulkhead , is it partition behind driver seat
Firewall. Between you and engine compartment. What model truck, 47/4900 ?
4900 4900
So, did ya find it?
I have checked all arroind brake peddle. Nothing there. Checked outside firewall and nothing there
Its got to be in the air line somewhere after the treadle. Follow the wires from the brake lights back toward the cab, and follow the air after it leaves the pedal. Somewhere they meet. Interior pic shows where my switch is in a 8300. Behind the upholstery. Firewall pic, that's supply to the pedal, and the lines out to the brakes. Find which set is going to the brakes and follow them.
No Sir
My outside fire wall resemble yours but i dont see a pressure valve
Will generally look like a automotive oil pressure switch, larger diameter tin with a black plastic contact retainer center crimped in place, two wire connectors. Between the seats is most likely.
Yes, i actually purchased one from international
On the older Internasties Straight Trucks they would bury them on the side of the foot valve under the dash, always less than accessible except for tiny hands/
They would use plunger switches on the pedals but those were strictly for juice brakes. You sure you dont have a tractor protection valve in between the seats on the floor against the back panel?
I will check behind seat tomorrow , i have a full seat all the way across. No bucket seats
Wiil check again, only thing that looks like the brake pressure switch is connected to PTO switch. I will look futher up under dashboard
Hey , it was behind the driver seat. Want to thank all of you for jumping in and helping.
Huh, I thought that was only tractors. Do you have air lines going out through the back wall of the cab? Or trailer air to the back of the frame? Either way, I'm glad you found it. There are so many options on those trucks, nobody can just tell you where it is.
Air lines come from back of frame
I dare say for speed of assembly the Air Brake cabs are all one stop commonality shop assembly, uncertain if to be road tractor straight truck or full truck with trailer combinations.
Any insight on this for a 1998 international 2554 model dump truck? No brake lights also
Behind the driver seat was where IH magically deployed their skills in positioning a switch that would be buried in detritus and filth.
I started a tread a while back about my '79 2574 not having ANY lights except blinkers,I was hoping some of you fellows could help me out,I'm stumped on it.
Start with Headlight Switch, Old School, single body all functions.
I will check on this to know for the future. It’s at a heavy equipment and truck mechanics house now down the road from me. He’s going to help me out with it. I’ll update when I get some info. Thanks!
