How do I know if my caravan brakes are working?
How to test electric trailer brakes
- Check magnet arm for wear.
- Pull the breakaway pin and measure the voltage at all magnets.
- If less than 12v recharge breakaway or upsize cabling to magnets.
- Check for magnet wear inside the drum.
- Install offroad magnets if magnet arms are worn.
How do you check electric caravan brakes?
You can indeed test a trailer’s electric drum brakes by directly applying +12V power from a fully-charged battery. You can apply this power to the hot and ground contacts on the trailer’s plug (see photo please) or to an individual brake assembly’s two wires.
Is a caravan classed as braked or unbraked?
Most caravans are braked (have their own brakes), but some trailer tents and other very small camping trailers may be unbraked. Make sure you select the correct towing capacity for your caravan or trailer tent.
How do you test a brake magnet?
To determine if a brake magnet has an internal short, touch the base of the brake magnet to the negative post of a 12-volt battery. Then, connect one of the brake magnet wires to the negative lead of a multimeter and the positive lead of the multimeter to the positive post of the battery.
How often should caravan brakes be replaced?
A caravan needs to be serviced every 10,000klms or every 12-18 months to make sure the brakes and bearings are all in good condition.
How often should you change caravan wheel bearings?

Which caravans are braked?
Are Caravan’s Braked or Unbraked? Any trailer (caravan) with a weight over 750kg is going to require a braking system. Therefore, for all intents and purposes, all ‘full-sized ‘ touring caravans in the UK are braked. However, most teardrop caravans are below 750kg, therefore may not be fitted with a braking system.
What should I do if my caravan brakes are not working?
Apply the brake fully before checking the balance bar in the centre of the caravan is at 90˚ to the rod from the hitch, and both sides pull evenly and the brake drums cannot be turned. If this is the case, replace the bungs and put the wheels back on, but only loosely tighten the nuts.
How do you check the brakes?

What size wire do I need for a caravan brake magnet?
A small wire size less than 1.5mm supply less than 10v to the brake magnets is not going to stop your caravan in a hurry. The ideal voltage at the magnet, when measured from the source of supply (battery), is 12v. The ideal current is 3.2A per magnet @ 12v.
