Brake shoes for SBS trailer, Alko axle?

You cant tell from the weight plate . Most Al Ko 1600 kg axles use the 200 x 51 hubs but not all . The 51 is the width of the shoe , so 1st has the axle got sealed bearings if so it should be the euro 2051 kit but if non sealed bearings are used you will have to take the hub off and check how wide the shoes are and post back on here and I should be able to tell which ones you have.
 
"apparently" there are only 2 types of brakes which are fitted on Boat Trailer Axles.
As I found when I needed brake shoes for my French "Satellite" Trailer.
There is ALKO and Knott.
Indenspension Trailers stock parts for both axles.
You may also find that places which sell Ivor Williams Trailers carry the same parts as they use the same axles.
