How do the disc brake operate in a motor cycle.

When we use disc brake, it gives more pressure on both sides of the plate with bigger brake application area than the drum brakes where pressure applied is less, only at a single side with smaller application area with a chance of more slippery after brake fad become smooter and thinner. This is part of my immagination after all I am not a engineer of any discipline. So my answer is only a theoretical . But something is better than nothing.

Disc Brakes are hugely more effective than drum brakes.
I will try and explain the workings as only then you would be able to understand the diffrence..
In a Drum Brake, there is an outer cylinder (which you can see as the outermost part of the hub of the wheel). The cylinder is free to rotate but is attached securely to the wheel.
Within that cylinder, there is a thing called a brake shoe. The shoe is stationary at all times. i.e. It does not rotate when the wheel rotates. When you press the lever for braking, the brake fluid forces the shoe to come in contact with the cylinder's inside wall and due to friction, the wheel stops which in turn makes the bike stop.
Now for Disc Brake: In a disc brake, there is the steel disc which you can see which is allowed to rotate with the wheel. It is the one with small holes on its surface.
On indian bikes, the clamps are Black in color. Within these clamps, there are tiny pads on both sides of the disc.
When you press the brake lever, the pads come in contact with the disc making the wheel stop which in turn makes the bike stop.
So now, in a drum brake, even though the contact match is larger than on a disc brake, the friction created is not so much. The reason for this is that the friction is just being created by a rubing effect.
In a disc brake, you basically clamp the disc, which creates a lot of friction. In this case, the friction is being created in a totally different plane to the motion.

The way a disc brake works is pretty simple if you examine one - the caliper has two brake pads inside it. Hydraulic pistons (or sometimes little levers) squeeze the pads against the disc to slow down the bike.
The biggest advantage of disc brakes is the way the braking surface is open to the passing air, letting it cool very quickly. My experience is that they're generally better than drums.

Disc brakes are definitely more effective than drum brake as the former evenly takes the load on all the spokes so that the vehicle comes to halt soon as compared to the drum brakes which applies to the rim and the load is also not equally distributed.

Disc Brakes dissipates heat build up, and give you more modulation over the drum brakes. They also give you more braking surface in turn give you more stopping power.

Yes

They are meant for stopping the bike instantly. ...... But they have taken the life many a riders.....
