Maintaining your trailer is crucial for safety, optimal performance, and preventing unexpected issues. Regular upkeep extends its lifespan and ensures it's ready for any journey. This guide outlines essential maintenance areas to keep your trailer in excellent condition.
1. Inspect and Maintain Your Trailer Brakes
Regular inspection of trailer brakes is vital, particularly after extended storage periods, to ensure they function correctly and safely.
- Test the braking system before every trip to ensure it engages smoothly and does not stick
- Inspect brake cables for wear, fraying, or rust
- Check brake drums and shoes for uneven wear and replace if necessary
- Ensure the handbrake engages and releases correctly without resistance
Over time, brake components can seize or wear down, making it harder to stop safely. If you notice reduced braking performance or unusual noises, servicing the brakes should be a priority.

2. Check Tyres for Wear and Proper Inflation
Tyres are the only point of contact between your trailer and the road, making them essential for safe towing. Underinflated or damaged tyres can cause blowouts, poor handling, and increased wear on suspension components.
- Check tyre pressures regularly and inflate to the manufacturer’s recommended PSI
- Inspect the tread depth to ensure it meets the legal requirement of at least 1.6mm
- Look for signs of cracking, bulging, or uneven wear, which could indicate suspension issues
- Ensure the spare tyre is in good condition and properly inflated

Maintaining the correct tyre pressure is crucial for stability and safety. Refer to the chart below for the correct pressures for different trailer wheel sizes
3. Test Trailer Lights and Electrical Connections
Faulty lighting and wiring issues are common causes of trailer-related MOT failures and road safety hazards. Ensuring that your trailer’s electrical system is functioning correctly is a key part of regular maintenance.
- Plug in the trailer electrics and check that brake lights, indicators, and sidelights are working correctly
- Inspect the wiring for damage, frayed connections, or corrosion
- Clean the plug and socket to prevent poor connections, particularly after winter storage
- If the trailer lights flicker or fail to work, a new towbar electrics kit or 13-pin plug realignment may be needed

4. Inspect Couplings and Hitch Components
The coupling system is what keeps your trailer securely attached to your tow vehicle, so it’s essential to check for wear and damage. A poorly maintained hitch can lead to dangerous towing instability.
- Ensure the tow hitch engages and locks securely onto the towball
- Check the coupling damper for signs of wear or resistance
- Apply grease to the tow hitch mechanism to ensure smooth operation
- Inspect the breakaway cable to confirm it is in good condition and properly attached
If your trailer knocks or jolts when braking and pulling away, it may indicate a worn coupling damper that needs replacing.

5. Check Suspension and Load Balance
A well-maintained suspension system ensures smooth towing and reduces wear on other trailer components. Poor suspension can cause instability, excessive tyre wear, and uncomfortable towing.
- Inspect leaf springs, shock absorbers, and axle components for damage or corrosion
- Make sure the trailer is evenly loaded, with heavier items positioned over the axle
- Avoid exceeding the trailer’s weight capacity, as this can damage suspension and braking systems

6. Keep Your Trailer Secure with Proper Locks and Safety Measures
Trailer theft is a major concern for owners, particularly for valuable or high-use trailers. Investing in security devices can help deter thieves and keep your trailer safe when not in use.
- Use a hitch lock to prevent unauthorised towing
- Fit a wheel clamp for additional security when parked
- Store your trailer in a secure location and use a tracking device if necessary
