Which brakes are more efficient, dry or wet, and why?

Question

Accepted Answer

Wet brakes are more efficient than dry brakes due to better heat dissipation and reduced wear and tear.

Wet brakes have a cooling effect due to the presence of water, which helps in dissipating heat generated during braking.
Wet brakes also have reduced wear and tear as the water acts as a lubricant, reducing friction between the brake pads and the rotor.
Dry brakes, on the other hand, generate more heat and can cause brake fade, reducing their efficiency.
Examples of wet brakes include those used in racing cars and heavy-duty vehicles.
Dry brakes are commonly used in motorcycles and bicycles.

In SI engines, the compression ratio typically ranges from 6 to 10, while in CI engines it ranges from 16 to 20. In SI engines, the antiknock quality of the fuel determines the upper limit of the compression ratio, while in CI engines, the compression ratio is high to allow the fuel to ignite at higher temperature and pressure.

Accepted Answer

Dry brakes and wet brakes are both braking systems, but there are some key differences between them. Wet brakes are immersed in oil or transmission fluid, which makes them more efficient and able to handle heat and pressure better. Dry brakes are not immersed in oil and are considered less efficient than wet brakes.
