Instructions
Loosen the cover on the front fork
Start by removing the front fork cover. You'll find the screws you need at the joint where the two sides meet.
Remove the screws behind the reflectors
There are additional screws behind the two reflectors. Remove these as well so that you can completely remove the cover.
Disengage the drum brake
Next, disengage the drum brake. To do this, loosen the drum brake adjustment screw.
Be careful while working so that you don't damage any parts of the brake mechanism.
Remove the front wheel
If you loosen both nuts now, you can remove the front wheel and pick it up.
Set all the disassembled parts aside in an orderly manner so that nothing is missing when you put them back together.
Clean or replace the drum brake
Once you've removed the front wheel, you can replace the drum brake with a new one or clean it.
To do this, open the drum brake and wipe it down thoroughly. Never use greasy or soapy cleaners. A brake cleaner combined with paper towels works best.
Prepare the tire and completely deflate it
To change a tire or inner tube, remove the tire and place it on a stable surface or carefully mount it. Be careful not to damage the axle.
Apply a generous amount of mounting compound to the tire and completely deflate it.
Remove the tire from the rim and take out the tube
Carefully place the tire lever against the tire and pry the tire off the rim little by little. Then unscrew the valve and remove the tube.
If necessary, clean the inside of the rim before installing the new parts.
Install a new inner tube or tire
Insert a new tube and make sure it isn't twisted. Apply mounting paste to the rim and the new tire again.
Use the tire levers to mount the new tire back onto the rim.
Inflate the tires and finish the installation
Inflate the tire to about 3.5 bar using the air compressor. Then, if necessary, let some air out until the desired pressure is reached.
Then remove any remaining thermal paste.
Reinstall the front wheel and drum brake
Reinstall the front wheel in the reverse order. Tighten both nuts, reattach the drum brake, and reinstall the cover on the front fork.
Finally, check that all screws are tight and that the brake is working properly.
Check the result
After assembly, check that all relevant parts are properly installed and functioning correctly. Pay particular attention to ensuring that the front wheel is securely fastened, that the drum brake is working properly, and that the tire is inflated to the correct pressure.
Frequently Asked Questions
Here you'll find answers to frequently asked questions about this repair.
Can I just clean the drum brake instead of replacing it?
Yes, if the drum brake isn't damaged or severely worn, it may be a good idea to clean it thoroughly with brake cleaner. Do not use lubricating or soapy cleaners.
What should I keep in mind when installing a new hose?
Make sure the tube isn't twisted when you put it in and that it doesn't get pinched when you mount the tire. Otherwise, it could get damaged right away.
What should I do if the brake doesn't work properly after reassembly?
Check again to make sure the drum brake is properly engaged and adjusted. If the braking performance is still not satisfactory, have the VMAX E-Scooter inspected E-Scooter a service center.
