My 4 wheel hubs are rusty. Except for the fact that it doesn't look great, can this have any practical negative impact?

Also, there's a particular speed (very slow, close to stop) where braking makes some annoying, loud noise. Can this be related to the rust?

As the image actually shows the outer surface of a drum brake, that can have surface rust on it with no issue, the interior surface however must not be rusty. The other surface that must not be rusty is the surface where the wheel mounts - rust there can mean wheels work loose.

For disc brakes, the hubs can show a surface coating of rust, which is fine. If it becomes pronounced, then the disc can separate from the hub making the brakes useless...

However, The braking surface must not be rusty, a good drive with sufficient braking usually sorts this out, if the rusty surface is only due to a short period of non-use. If the rust is heavy, then the discs should be cleaned or surface ground and measured before being put back into service with new pads.

  • May want to add something about drums, since that photo looks like a drum brake.

  • This can be fixed by having a solid wheel cover so you cant see the rust on the outside of the drum. Nov 19, 2018 at 15:28
  • Or a coat of paint over the outside of the drums is perfectly fine. Make sure you don't paint disks though ;)
