Why is it dangerous to use compressed air to blow off dust from a brake caliper assembly during service?

1. It can aerosolize brake dust, which may contain hazardous materials like asbestos or heavy metals, risking inhalation
2. It will force brake fluid out of the master cylinder reservoir
3. It will warp the brake disc due to rapid cooling
4. It can damage the caliper's sliding pins by pushing them out of alignment
