Saw a VO3x tires not moving during braking during wet weather

What is this?

Is this the front disc brake? Or the brake locking system?

it’s probably jus a slip of the tires. it’s normal on a rainy day, or else ppl dun have to drive more carefully and told not to speed.

Common problem with multi axle vehicles, especially those container trailers.

When braking force is applied, due to wear/tear, miscalibration, some brakes may "eat" earlier than the rest, resulting in some wheels locking up earlier than the rest. Also depends on the thread of the tires as well.

This is called a 'tyre lock'. It happens when the force applied by the brakes is greater than the ability of the tyres to grip the road surface. Hence, it stops rolling or gets locked in place. The wet weather further increases the chances getting a tyre lock due to a thin layer of water on the road surface. The highly grippy characteristic of Volvo brakes adds to the factor too. Getting a tyre lock is very dangerous because there will not be any traction on the wheels and you lose control of the vehicle. But considering the enormous weight and slow speed of a VO3x, it is not so alarming. Some cars have ABS (Automatic Braking System) to avoid this. A computer will slightly decrease the brake pressure when the tyres begin to lock.

I once saw an LO3X on 74 locking the centre axle. Nothing much, but my esteem in DDs went down at once.
