How To Adjust Knott Trailer Brakes

Properly adjusting your Knott trailer brakes is essential for ensuring safe towing, optimal braking performance, and prolonging the lifespan of your trailer’s braking system. Whether you're a seasoned professional or a casual camper, understanding the correct procedure for adjusting trailer brakes can save you time and money. This comprehensive guide will walk you through the steps required to adjust Knott trailer brakes effectively, ensuring your trailer operates smoothly and safely on the road.

Understanding Knott Trailer Brakes

Knott Manufacturing Company has been a trusted name in trailer brakes and suspension systems for decades. Their trailer brake assemblies are designed to provide reliable stopping power and durability. Before diving into adjustment procedures, it’s important to understand the basic components of Knott trailer brakes:

• Brake Drum: The rotating part that houses the brake shoes and friction surfaces.
• Brake Shoes: The components that press against the drum to create braking force.
• Adjuster Mechanism: A device that allows for the tightening or loosening of brake shoes to maintain proper clearance.
• Brake Actuator: The mechanism that applies force to the brake shoes when the trailer is hitched to a towing vehicle.

Proper adjustment ensures that the brake shoes make adequate contact with the drum without causing excessive wear or drag. Over time, brake shoes wear down, which can lead to decreased braking performance. Regular adjustments are necessary to maintain safety and efficiency.

Tools and Materials Needed

• Screwdriver or Brake Adjuster Tool: For turning the adjuster mechanism.
• Jack and Jack Stands: To lift and support the trailer safely.
• Wheel Wrench: To remove wheels if necessary.
• Gloves: To protect your hands during the process.
• Safety Glasses: To protect your eyes from dust and debris.
• Lubricant or Brake Cleaner: Optional, for cleaning parts if needed.

Preparing for Brake Adjustment

Before starting the adjustment process, ensure your trailer is parked on a level surface and securely supported with jack stands. Always follow safety precautions to prevent accidents. Here are the initial steps:

• Engage the trailer’s parking brake if applicable.
• Chock the wheels that are not being lifted to prevent movement.
• Use a jack to lift the trailer axle, then support it securely with jack stands.
• Remove the wheel to access the brake assembly, if necessary.

Note: Some trailers allow for brake adjustment without removing the wheel, depending on the design. Check your trailer’s manual for specific instructions.

How To Adjust Knott Trailer Brakes

Adjusting Knott trailer brakes involves setting the brake shoes’ clearance to ensure proper contact with the brake drum during operation. The goal is to have just enough clearance so that the shoes lightly contact the drum when the brakes are not applied.

Step 1: Identify the Brake Adjuster

Locate the brake adjuster mechanism. It is typically found at the back of the brake assembly, accessible through the backing plate. Depending on your trailer model, it may be a star wheel or a screw-type adjuster.

If your trailer has a manual adjuster:

• Look for a small wheel or screw that can be turned to tighten or loosen the brake shoes.
• Some models have a slot or opening to insert a screwdriver or brake adjuster tool.

Step 2: Turn the Adjuster to Set Clearance

Using the appropriate tool:

• Turn the star wheel or adjuster mechanism in the direction indicated by the manufacturer to tighten the brake shoes. Usually, this involves turning the wheel upward or clockwise.
• As you turn, observe the brake shoes moving closer to the brake drum.
• Continue adjusting until the shoes are just about to contact the drum lightly, or until you feel resistance when turning the drum manually.

Important: Do not over-tighten, as this can cause brake drag and uneven wear.

Step 3: Check the Brake Shoe Contact

After adjusting, manually rotate the wheel or drum to ensure the shoes are close but not rubbing excessively. There should be a slight drag or resistance without forcing the wheel to turn.

If the wheel does not rotate freely, back off the adjuster slightly to prevent overheating and excessive wear.

Step 4: Repeat the Adjustment on All Wheels

Repeat the above steps for each wheel on your trailer, ensuring consistent brake shoe clearance across all axles. Proper synchronization helps maintain even braking performance and trailer stability.

Step 5: Test the Brakes

Once adjustments are complete:

• Reinstall the wheels and lug nuts securely.
• Lower the trailer from the jack stands carefully.
• Take the trailer for a slow test drive in a safe area to verify brake performance.
• Apply the brakes gently to check for smooth, effective stopping power.

If you notice abnormal noises, dragging, or poor braking, revisit the adjustment process or inspect for worn brake components.

Additional Tips for Maintaining Knott Trailer Brakes

• Regularly inspect brake shoes and drums for wear and damage.
• Lubricate adjuster mechanisms with appropriate grease to prevent seizing.
• Clean brake components with brake cleaner to remove dust and debris.
• Replace brake shoes and drums if they are excessively worn or damaged.
• Follow your trailer manufacturer’s recommended maintenance schedule for brake systems.

Common Troubleshooting Tips

• Brake Shoes Not Adjusting Properly: Check for dirt, rust, or debris in the adjuster mechanism. Lubricate or replace if necessary.
• Brake Drag: Over-tightening the shoes can cause dragging; back off the adjuster slightly.
• Uneven Brake Wear: Inspect for sticking components or misalignment.
• Inconsistent Braking: Ensure all brakes are properly adjusted and functioning equally.

Conclusion

Adjusting Knott trailer brakes is a straightforward yet vital maintenance task that ensures your trailer's braking system is responsive and reliable. Regular inspections and adjustments help prevent brake failure, reduce wear, and enhance safety during towing. Always refer to your specific trailer’s manual for model-specific instructions and safety guidelines. With proper care and maintenance, your Knott trailer brakes can deliver optimal performance for years to come, giving you peace of mind on the road or at the campsite.
