Understanding Caravan Brakes
Caravans in the UK use over-run brakes, a type of braking system that activates when the tow vehicle slows down or stops, and is required for all caravans and trailers rated above 750kg weight capacity.
What Kind Of Brakes Are Used For UK Caravans?
In the United Kingdom, most caravans have an ‘over-run’ braking system specifically tailored for safe towing. This system ensures reliable and smooth stopping power when you need it.
The beauty of over-run braking systems lies in their simplicity and efficiency while on the road. As your tow car slows down, the caravan’s momentum presses against the sprung draw-bar, activating the caravan’s brakes automatically.
Understanding The Function Of Overrun Brakes
Over-run brakes play a crucial role in ensuring the safety of campers towing caravans behind their vehicles. As a camper, it’s essential to understand how these brakes work and why they’re critical.
Over-run brakes automatically apply the caravan’s braking system when you slow down or come to a halt with your tow car.
The critical component of the over-run brake system is the ‘overrun device’, which generates draw-bar force. The device is located inside the hitch lock of the caravan, and uses the forward momentum of the caravan to move a rod which activates the brakes when the tow car slows. To help visualize this process, imagine yourself walking backward with a shopping trolley: when slowing down or stopping abruptly while pulling the trolley, its momentum would cause it to bump into you – this same concept applies to your tow car and caravan.
Incorporating over-run brakes into your towing setup enhances overall safety and provides peace of mind during long journeys or heavy traffic situations where frequent stops may be required.
Furthermore, using additional features like a breakaway cable alongside over-run brakes can mitigate potential dangers if an unlikely detachment between your car and trailer occurs.
What Is The Breakaway Cable?
A caravan breakaway cable is a safety device for towing caravans or trailers. It is designed to activate the brakes on the caravan or trailer if it becomes detached from the towing vehicle while in motion. The breakaway cable connects the towing vehicle and the caravan or trailer’s braking system.
If the caravan or trailer becomes detached from the towing vehicle, the breakaway cable will be pulled taut, activating the brakes and bringing the caravan or trailer to a stop. This helps prevent the runaway of the detached caravan or trailer, reducing the risk of accidents or damage.
According to UK law, all towed vehicles, such as caravans, must have a breakaway cable that adheres to appropriate standards and practices. Ensuring this cable is correctly installed and securely attached is paramount for safeguarding yourself and others on the road.
To provide guidance on proper attachment techniques, The Caravan Club has compiled an invaluable resource detailing best practices for fitting breakaway cables.
How Caravan Brakes Work
Caravan brakes work through the use of brake pads and shoes, which are pressed onto the brake rotors or drums to slow down or stop the trailer when activated by the over-run brake mechanism.
Brake Pads And Shoes, Brake Rotors And Drums
It’s important to have a basic understanding of how caravan brakes work. One essential component is knowing about the different parts that make up the brake system. Here’s what you need to know about brake shoes and drums:
- Brake shoes: These components press against the brake drum to slow down or stop your caravan. Brake pads are used with disc brakes, while brake shoes are used with drum brakes. They wear over time and will need to be replaced periodically.
- Brake drums: These are cylindrical surfaces that rotate along with your wheels. When you apply your brakes, brake shoes push against them, which creates friction and slows down your caravan. Over time, brake drums can become worn or develop grooves, affecting their performance.
Understanding these components and how they work together can help you better maintain your caravan’s braking system, ensuring you can travel safely on your adventures.
What is a Caravan Handbrake?
The caravan handbrake, or the parking brake or emergency brake, is a mechanical braking system designed to keep the caravan stationary when it is not being towed. It operates independently of the towing vehicle’s braking system. Here’s how the caravan handbrake typically works:
- Lever or Pedal: The handbrake is usually operated by a lever or pedal within the caravan’s interior. It is commonly located near the driver’s seat or on the dashboard.
- Cable or Rod Mechanism: When the handbrake lever or pedal is engaged, it activates a cable or rod mechanism that extends to the caravan’s braking system.
- Brake Shoes or Pads: When engaged, the cable or rod mechanism applies force to the caravan’s brake shoes or pads. These brake shoes or pads press against the inner surface of the brake drum or rotor, creating friction and generating braking force.
- Holding the Caravan: Once the brake shoes or pads are engaged, they prevent the wheels from rotating, effectively holding the caravan in place. This ensures the caravan remains stationary, even on inclines or uneven surfaces.
- Releasing the Handbrake: The lever or pedal is disengaged to release the handbrake, which releases the tension on the cable or rod mechanism. This allows the brake shoes or pads to retract from the drum or rotor, allowing the wheels to rotate freely again.
It’s important to note that the caravan handbrake is not designed to provide the same braking force as the towing vehicle’s brakes while in motion. Its primary purpose is to secure the caravan when parked and prevent it from rolling or moving unintentionally. Regular maintenance and inspection of the handbrake system are essential to ensure its proper functioning and maintain the caravan’s overall safety.
Brake Shoe Inspection And Replacement
A critical aspect of maintaining your caravan brakes is to inspect and replace the brake shoes when needed. Here are some tips to help you with this process:
- Inspect the brake shoes regularly: It’s essential to inspect them regularly so you know when they need replacing. Look for signs of wear, such as cracks or thinning of the lining. If in doubt, it’s always best to get them checked by a professional mechanic.
- Check for dust: Caravan brakes generate a lot of dust, which accumulates on the shoe linings. This dust can cause uneven wear on the brake shoes and reduce their effectiveness. To prevent this, make sure that you clean out any dust from inside the brakes during your maintenance routine.
- Replace when necessary: When you notice significant wear or damage to your caravan brake shoes, it’s recommended that you replace them as soon as possible. It can lead to more expensive repairs down the road.
By following these steps and keeping your caravan brakes well-maintained you can ensure that you’re safe on the road and get maximum performance from your braking system.

How To Brake Your Tow Car In An Emergency
If you ever find yourself in an emergency while towing your caravan, knowing how to brake your tow car safely and effectively is crucial. The first step is to avoid slamming on the brakes suddenly, which can cause the tow rope or trailer to jolt and become unstable.
It’s essential always to keep a safe distance from other vehicles when towing, so you’ll have enough time to react appropriately in case of any sudden braking by others.
Additionally, ensure that your handbrake is functioning correctly before embarking on any journey, as this will act as an additional safety measure in case of brake failure.
Importance Of Weight Distribution
One of the essential factors to remember when towing a caravan is weight distribution. Without proper weight distribution, you risk your caravan becoming unstable, making it difficult to control and increasing the likelihood of an accident.
To avoid this, make sure that you distribute your load evenly throughout your vehicle and trailer. A weight distribution hitch can help with this by spreading the weight across your car and the trailer, ensuring they both ride smoothly on the road.
Regularly checking tire pressure and inspecting suspension components can ensure that your load is distributed correctly and minimize any potential risks on the road.
How To Test Caravan Brakes
As a camper, ensuring that your caravan brakes work effectively before embarking on a journey is important. Here’s how to test them:
- Find a safe and level area: Look for a flat and open space where you can safely perform the brake test without any obstacles or traffic nearby.
- Disconnect the breakaway cable: Before testing the drum brakes, ensure the breakaway cable is disconnected from the towing vehicle to prevent the brakes from activating during the test.
- Engage the caravan handbrake: Ensure that the handbrake on the caravan is engaged. This will help keep the caravan stationary during the brake test.
- Gradually apply the towing vehicle brakes: Get into the towing vehicle and slowly apply the brakes. Observe how the caravan responds to the braking force. It should gradually slow down and come to a stop without any pulling or uneven braking.
- Listen for unusual noises: While applying the brakes, listen for any unusual noises such as grinding, squealing, or rubbing. Unusual noises may indicate issues with the brake components that require inspection or maintenance.
- Check for consistent braking: Ensure that all caravan wheels are braking evenly. If you feel uneven braking or pulling to one side, it may indicate an adjustment or maintenance issue with the drum brakes.
- Perform a visual inspection: After the brake test, inspect the drum brakes for any signs of excessive wear, damage, or oil leakage. If you notice any problems, it’s advisable to have a professional inspect and service the brakes.
Remember, regular maintenance of your brakes is crucial for safe and enjoyable travels with your caravan. Be sure to follow manufacturer guidelines for servicing and always prioritize safety when towing on the roads.
