1

Loosen the brake cable

First loosen the nut on the brake cable using a 14 mm wrench. This nut holds the brake cable attached to the drum brake.

As soon as the nut is removed, you can pull the brake cable out of the holder and detach it from the brake drum.

Then carefully remove the spring and the rubber cover from the brake cable.

2

Remove the front wheel

Now loosen the two nuts on the wheel axle using a 17 mm wrench (one nut on the left and one on the right).

Once both nuts have been removed, you can carefully remove the front wheel from the fork.

3

Remove the spacers and brake drum

Now carefully remove the spacers on both sides of the axle.

Then pull the old brake drum out of the wheel.

4

Insert the new drum brake

Insert the new drum brake into the wheel.

Make sure that the notch in the drum brake is facing upwards. This position is important for the brake to function correctly.

5

Fitting the wheel and adjusting the brake

First push the spacers back onto the axle.

Important:
In the direction of travel, there should be 1 spacer on the right and 2 spacers on the left. Pay close attention to this arrangement when reassembling so that the wheel sits correctly and the brakes work properly.

Then carefully reinsert the wheel into the fork and tighten the axle nuts with the 17 mm wrench.

Then reinsert the brake cable and secure it with the 14 mm nut.

Bremskabel wieder montieren

First push the spring and then the rubber cover back onto the brake cable.

Set the brake correctly: The handlebars should be in the upright position. Apply the brake until it is just before it starts to drag. This will give you an optimum braking effect.

Check the result

After assembly, check that all parts are correctly fitted and that the wheel can turn freely.

Then carefully test the brake function to ensure that the drum brake engages properly.

After the repair, test your VMAX e-scooter carefully when stationary or on a short distance before using it normally again in everyday life.

Frequently asked questions

Here you will find answers to frequently asked questions about replacing the drum brake.

Why does my drum brake grind after installation?

In most cases, the brake cable is too tight. Loosen the adjusting nut slightly until the wheel can turn freely. The brake should only engage when you pull the brake lever.

My brake barely grips - what could be the reason?

First check the adjustment of the brake cable. Tighten the adjusting nut slightly until the brake lever has noticeable resistance. Make sure that the handlebars are in the upright position so that the adjustment is correct.

What happens if the spacers are fitted incorrectly?

If the spacers are not fitted correctly, the wheel will not be centered in the fork. This can cause the brakes to drag or the wheel may not run smoothly. In the direction of travel, one spacer should be fitted on the right and two on the left.

Does the notch in the drum brake really have to point upwards?

Yes. The notch ensures that the brake sits correctly in the bracket. If it is positioned incorrectly, the brake cannot grip properly or even come loose.
