Product Information

Full details

The AB Tools Long Life Trailer Brake Cables are designed for trailer owners and mechanics maintaining Knott or Ifor Williams trailer systems who prioritize durability and reliable braking performance. These cables feature a specialized blue protective sleeve that significantly extends the lifespan of the inner cable, though users must ensure their trailer system specifically requires an 1130mm outer sheath length to guarantee proper fitment before installation.

FAQs

Can I use these cables on a non-Knott trailer?

These cables are specifically designed for Knott and Ifor Williams systems; they may not be compatible with other axle manufacturers.

Why is the inner cable sleeve blue?

The blue sleeve is a specialized coating designed to protect the inner wire from corrosion and provide a smooth surface for long-term reliability.

How do I measure my current cable to see if this fits?

Measure the outer metal sheath from shoulder to shoulder. If your measurement is 1130mm, these cables will fit.

Do I need to grease the cable after installation?

No, these cables come pre-lubricated from the factory and are ready to use immediately.

Does this pack contain everything I need?

Yes, this is a pair of cables including the M8 spherical nuts required for installation.

Is it necessary to replace both cables at the same time?

Yes, replacing them in pairs is standard practice to ensure balanced braking performance and prevent the trailer from pulling to one side.

Troubleshooting

Brakes feel 'soft' or travel too far before engaging

Adjust the M8 threaded nut at the equalizer to increase tension on the cable.

Brake does not release fully

Check that the cable is not kinked and verify that the brake shoe return springs are functioning correctly.

Difficulty fitting the Knott end

Ensure the brake lever is fully in the 'off' position to allow maximum slack in the cable.

Pros and Cons

Pros

  • High-durability blue protective sleeve prevents inner cable seizing
  • Pre-lubricated for immediate installation without extra effort
  • Includes M8 spherical nuts for a complete mounting solution
  • Professional-grade construction suitable for frequent use

Cons

  • Specific 1130mm length must match existing setup perfectly
  • Not compatible with braking systems requiring non-detachable cable designs
  • M8 threaded end requires precise tension adjustment

Setup, Compatibility & Care

Installation requires basic mechanical knowledge and an understanding of your trailer's brake adjustment procedure.

  1. Ensure the trailer is securely jacked and supported on axle stands before removing wheels.
  2. Disconnect the old cable from the equalizer and the brake backplate.
  3. Feed the new cable through the housing, ensuring the blue protective sleeve is correctly positioned to avoid kinking.
  4. Secure the Knott detachable end to the brake mechanism and thread the M8 end through the equalizer.
  5. Tighten the included M8 spherical nuts until the slack is removed, then test the brake lever or overrun damper to ensure even tension.

Regular care involves checking the blue protective sleeve for cracks or tears during your annual service interval. If the sleeve is compromised, replace the cable immediately to prevent moisture ingress.
