Replacing the trailer or caravan brake drum
Besides the brake shoes, the brake drum also wears out over time. You can replace it relatively easily yourself. However, it is important to know which Axle is under the Trailer or caravan. We have the most common brake drums directly available from stock.
Always replace the Axle brake drum with the same brand.
What brand of brake drum does the Axle have?
Every brand of Trailer uses a few manufacturers for the undercarriage. The fact that there are only a few options also makes it easier to determine which brake drum you need. The leading brands are:
- BPW ( now also part of Al-Ko)
Checking the dimensions of the drum
The brake drum has a bearing which is often already pressed in. It is important that it matches the existing bearing. It is also important to measure the diameter and depth of the drum. This is the same when you also replace the brake shoes. If you know what brand of Axle you have and you measure the diameter and depth of the drum, you can hardly go wrong. Still in doubt? Then contact us to make sure you order the right parts. We will be happy to help!
How does the drum brake work?
When braking, the brake shoes press against the drum in order to brake the wheels. Logically, the brake shoes wear out faster than the cast iron drum, but over time the brake drum will also wear out. We always recommend replacing the Brake drums with the same brand as originally fitted to the Axle.
Detaching the Brake drum from the Axle
To detach the Brake drum from the Axle, you should first unscrew the brake completely with the adjustment screw at the rear. This will prevent the drum from getting stuck behind the brake shoes. then, after removing the hub caps, you can unscrew the hub nut and loosen the brake drum. You can then replace both the brake drum and the brake shoes.
