Electric brake shoes include a primary and a secondary shoe for one 10 inches or 12-inch backing Plate.
Install larger shoe towards the back of the trailer, smaller shoe towards the front of the caravan.
One axle uses two pairs of brake shoes.
The critical thing to look for when inspecting trailer and caravan shoes is the slot or hole in the top of the shoe.
- The park brake attachment is used on slotted brake shoes. (Alko)
- Dexter shoes use a spring on the top to hold shoes together.
Purchase electric backing plates here.
So how do caravan brake shoes work?
When viewing 10-inch shoes, you will notice they are different. It is possible to install caravan brakes shoes back to front.
One shoe is shorter than the other.
- The longer shoe is called the primary brake-shoe, and it faces the rear of the caravan.
- The short shoe is called a secondary brake shoe and faces the front of the caravan.
The magnet, when energised will attach itself to the inside of the moving brake drum and remain connected during braking.
The attached magnet on the drum forces the brakes shoes during a forward motion causing deacceleration.
Tip: If your electric magnet and shoes need replacing, check the other components as they may also be showing signs of wear. A better solution may be to buy an entire backing plate and bolt it onto the weld ring.
