Difference between Al-ko and Dexter brake shoes
- Al-ko brake shoes are slotted at the top of the shoes.
- Dexter Brakes shoes have a hole at the top of the shoes.
Install a larger shoe towards the back of the trailer and a smaller shoe towards the front of the caravan.
One axle uses two pairs of 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 Alko park brake has horizontal slots for the shoes
- Dexter shoes use a spring on the top to hold shoes together

So how do electric brakes work?
When viewing 10-inch shoes, you will notice they are different. It is possible to install caravan shoes back to front.
Electric brakes will not work without a brake controller.
Brake Shoe Installation
A common question is "Which way do you put 10-inch brake shoes on".
- The longer shoe is called the primary brake shoe and faces the caravan's rear.
- 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 brake's shoes during a forward motion causing deceleration.
Tip: If your electric magnet and shoes need replacing, check the other components, as they may also show signs of wear. Electric magnets need replacing when the wear holes are no longer visible.
A better solution is to buy an entire backing plate and bolt it onto the weld ring.
The supply cable to the rear tail light globes is only large enough to power 21w, which is 1.75A. The power supply required to power 4 electric brake magnets is 4 x 3.2A or 12.8Amps.
