Which risk increases when a hydraulic braking system operates under heavy braking?

💡 Explanation

Pump cavitation increases because the rapid pressure drop induced by the brake actuation causes vapor bubbles to form in the hydraulic fluid. Therefore cavitation increases the risk of brake failure, rather than increased fluid density or viscosity changes.
