Knott Single Axle Balance Bar Kit - OEM Number: 572013

The Knott Single Axle Balance Bar Kit (OEM 572013) is a genuine replacement trailer brake compensator kit designed for use on Knott and Knott Avonride single axle braked trailers. It forms a critical part of the mechanical overrun braking system, ensuring that braking force is distributed evenly between the left and right brake cables for balanced, consistent, and safe braking performance.

Manufactured to OEM specifications, this balance bar kit is engineered for durability, corrosion resistance, and reliable operation in demanding road, agricultural, commercial, and plant trailer applications. The galvanised steel construction provides long-term protection against rust while maintaining smooth and accurate brake cable movement.

FUNCTION AND OPERATION

• Equalises braking force between both trailer wheels
• Connects the overrun brake rod to the brake cables
• Helps ensure balanced and efficient trailer braking
• Reduces uneven brake wear and improves braking stability
• Suitable for both threaded and Pronto-Fit brake cable systems
• Designed for reliable operation in commercial and heavy-duty trailer applications

IMPORTANT INFORMATION

Always confirm the correct OEM part number, brake system type, and cable configuration before ordering, as Knott has produced several balance bar designs with different centre dimensions and cable arrangements. OEM 572013 is designed for single axle Knott 55-centre systems and differs from the older Avonride 65-centre compensator kits and twin axle variants. Worn or seized balance bars can cause uneven brake application, premature brake shoe wear, reduced braking efficiency, and trailer instability under braking. When replacing the balance bar kit, it is recommended to inspect the brake cables, overrun linkage, return springs, and brake adjustment to ensure optimum braking performance and long-term reliability.
