Possibly. Please share your wheel drawing or 3D model so we can confirm there is no interference between wheel, caliper, and disc.

A drum brake system uses internal brake shoes that press outward against a drum to stop the vehicle — similar to using your hands to press inside a spinning barrel.

A disc brake system uses calipers to squeeze brake pads against a rotating disc — like pinching a spinning plate with tongs to stop it.

Drum Brakes: Better for low-speed, low-load vehicles. Cost-effective and easy to maintain.

Disc Brakes: Suitable for high-speed or heavy-load vehicles. Offer stronger, more responsive braking.

It uses a worm screw to engage with a gear and create friction that locks the wheels — much like tightening a bolt to hold something in place.

To engage: The worm rotates to lock the gear, preventing wheel movement.

To release: Reverse rotation frees the gear, allowing movement again.
