The Knott Style Brake Cable (PO146) is a high-durability replacement component designed for commercial and private trailer operators, particularly those utilizing Ifor Williams trailers. Its primary benefit is the use of corrosion-resistant stainless steel, which makes it an excellent choice for boat trailers frequently exposed to saltwater or wet environments. While the cable is pre-lubricated and ready for installation, users should carefully verify their existing cup and thread dimensions before purchase, as subtle compatibility differences exist between various trailer brake systems.

Yes, the stainless steel construction is specifically designed to resist rust and corrosion caused by marine environments.
It is compatible with Knott-equipped trailers including Ifor Williams, Bateson, Brian James, and Indespension.
No, the cable arrives pre-lubricated and is ready for immediate installation.
The red sleeve protects the inner cable from premature wear and ensures smoother operation within the sheath.
No, this cable is specifically designed for Knott style braking assemblies.
The cup has an internal diameter of 18.5mm and an external diameter of 22mm.
Loosen the M8 adjuster nut slightly to provide more slack in the inner cable.
Check for stretched cable housing or ensure the Knott fitting is fully seated in the backplate.
Verify the sheath length (1830mm) against your original cable; if they differ, the cable is not compatible with your brake linkage.
To install, ensure the trailer is supported on jack stands and the parking brake is fully released. Remove the old cable by detaching the Knott fitting from the backplate and unscrewing the M8 threaded bar from the balance bar mechanism. When installing the PO146, ensure the cup fits securely (18.5mm internal diameter) into the housing. Do not over-tighten the domed nut initially; adjust until there is minimal slack but no drag on the drum. For care, although the cable is pre-lubricated, an annual inspection for fraying at the cable ends is recommended, especially in high-mileage commercial use.
