CNH 731159034 Pneumatic Trailer Brake UK Type Installation Instructions

On tractors and ag machines that spend their days hauling loaded trailers on roads and in the yard, the pneumatic trailer brake system has to be installed right the first time. This CNH installation instruction set helps you route the lines, mount the components, and hook into the machine’s existing hydraulic and air circuits correctly for UK‑type trailer brakes. When a trailer isn’t braking evenly or an air line’s been disturbed during other repairs, I’d pull this document to verify the connector locations, washer counts, and pipe routing before I start cracking fittings loose.

Applications & Use Cases

• Install a new trailer brake kit on a compatible CNH tractor, following the correct mounting points and connections.
• Trace and verify air and hydraulic connections when you’ve got a braking imbalance or a trailer that’s slow to respond.
• Confirm the correct routing of air pipes to avoid chafing, tight bends, or interference with other components.
• Identify hardware like washers and connectors so you don’t mix up similar-looking parts during reassembly.
• Check your work after repairs to ensure the pneumatic brake system matches factory layout before road testing.

FAQ

Q: Can I use this on a tablet in the field?

A: Yes, it’s practical to keep a digital copy on a tablet or phone so you can zoom in on diagrams right next to the machine.

Q: Is it worth printing this out?

A: For installation jobs, a printed copy is handy—you can mark it up, tape key pages to the cab, and keep greasy hands off your device.

Safety Note

Always depressurize both air and hydraulic systems and secure the machine and trailer before loosening any brake lines or fittings.
