What is the potential hazard if a front fork oil seal is leaking and left unrepaired?

1. Fork oil can drip down onto the front brake caliper, pads, and disc rotor, causing a severe loss of front braking force.
2. The engine oil level will drop rapidly because the fork is connected to the crankcase.
3. The headlight bulb will burn out due to chassis vibrations.
4. The tyre pressure will decrease due to oil contacting the tyre valve.
