What protects the braking system on the main gear wheels of the A320?

The primary mechanism that protects the braking system on the main gear wheels of the A320 is anti-skid protection. This system is essential in preventing the wheels from locking up during braking, especially on wet or slippery runways. The anti-skid system continuously monitors the wheel speeds and compares them to the aircraft's forward speed. If it detects that a wheel is about to lock up, it automatically modulates the brake pressure on that wheel to optimize braking efficiency and maintain traction.

This capability significantly improves the aircraft's stopping performance and enhances safety during the landing phase. By ensuring that the wheels do not skid, the anti-skid protection allows for more controlled and effective braking while also reducing wear and tear on the tires and brake components. This system is an integral part of the aircraft's overall braking strategy, ensuring that the aircraft can stop promptly and safely in various conditions.
