How do I find out what type of wheel brake and brake shoes my trailer has?
The quickest way is to check the markings on the vehicle. Only if these are missing should you take measurements.
1. Axle type plate — the best source. It is usually located in the centre of the axle tube. Ideally, the type of wheel brake will be stated directly on it. With AL-KO, you’ll often find an ETI number (spare part identification number) — this allows the brake to be uniquely identified. If both are missing, the permissible axle load, manufacturer and type number will help.
2. Anchor plate — the second source. The anchor plate is the mounting plate behind the brake drum. The manufacturer, part number and exact wheel brake type are often stamped on the back. A useful identifying feature: red cover caps on the backing plate indicate a brake with automatic adjustment.
3. Stamped markings on the brake shoes. The manufacturer’s name or a number is often stamped on the removed shoes themselves. Any such number is helpful — we have a database of reference numbers which often allows us to identify the part with certainty.
4. If nothing is legible: take measurements. Two measurements are usually sufficient:
- Inner diameter of the brake drum, for example 200 mm
- Brake shoe or lining width, for example 50 mm
This gives the standard designation 200 x 50. Please also send photos: one of the complete brake assembly, one of the anchor plate, and one of the removed brake shoe.
One thing you mustn’t get mixed up about: it’s the manufacturer of the axle that matters, not that of the trailer. A trailer of brand X may have an axle from AL-KO, Knott, BPW or Peitz. And identical dimensions do not necessarily mean an identical fit — an AL-KO axle requires AL-KO brake shoes, even if another manufacturer offers the same size.
Select by manufacturer: brake pads and brake shoes. You’ll also find matching brake drums and brake cables here.
