What should you inspect visually about the brake chambers and slack adjusters during a pre-trip walk-around?

Pick an answer

1. Only their serial numbers, not their physical condition, skipping the visual check that would actually catch damage or wear
2. That they are securely mounted, not visibly damaged, and the pushrod travel looks within normal range
3. That they are covered with a protective cloth whenever the vehicle is parked
4. Only that they are painted the same color as the axle
