• Question: How does a formula 1 car over come vapour locking in the braking system as their braking systems are under extreme pressure?

      Good question, although I’m not sure of the answer!

      Hi, not my strongest subject, formula one but even a numpty knows that vapor lock occurs in the fuel system, not the braking system. Vapour lock is when fuel under pressure goes form a liquid to a gas, making it difficult for the fuel pump to move it into the engine, causing loss of power or even problematic stalling.
      Formula 1 cars use disc brakes much like any high quality road car but the hydraulic fluid utilised is not prone to vapourising so an issue similar to vapour lock is unlikely.
