To quote Sheldon Brown: “The fastest that you can stop any bike of normal wheelbase is to apply the front brake so hard that the rear wheel is just about to lift off the ground.

What are the disadvantages of disc brakes on bikes?

This leads to longer response times, less efficient braking and less bike control. Disc brakes use calipers mounted to the fork in front and the frame in back, and rotors (the discs) mounted to the wheel hubs. When you squeeze the brake levers, the brake pads inside the calipers squeeze the discs to slow the wheels.
