Nowadays, disc brakes are also coming in bikes along with drum brakes. The front and rear tires of the motorcycle are fitted with disc brakes. Disc brake is employed for better and efficient braking. Let us know how disc brake works in motorcycle.

We have seen that the braking mechanism of almost all the bikes is changing speed with time. Gone are the days of drum brakes which are only seen on normal commuters and cost effective bikes. The reasons for the paradigm shift are also appropriate, but the benefits are something that places a great deal of importance on the form and factor. Yes, it is true that its cost is very high as compared to conventional drums.

This is a new braking technique. With the help of this disc, the braking of the motorcycle becomes tremendous. This system brings the motorcycle to a complete stop. The disc brake fitted in the front tire is about 70 per cent more effective in controlling the speed of the bike, while the drum brake fitted in the rear tire works only 30 per cent. Because drum brakes are not very effective in case of sudden braking.

The motorcycle overheats while running. The brake shoe generates more heat due to friction where braking is not very effective. Disc brakes are very effective in this situation. Because it also cools down easily. You can install disc brakes on any bike. It costs about 3 to 5 thousand rupees to install it. Remember, if you apply the disc brakes too hard, accidents can happen.

Disc brake works on the principle of hydraulic pressure and Bernoulli’s principle. Disc brakes require discs to start. It is a metal disc with many cracks and holes over its entire area. Thickness and width depend on the manufacturer, but for the most basic, discs have holes in them. The purpose of those, we will come to later.

To apply force to the disc are brake pads or brake calipers. These are nothing but rough surface plates at both the ends of the disc. These pads are attached to a fluid container that holds brake fluid that flows through a brake fluid pipe from a reservoir located on the bike’s handlebar. Might sound a bit confusing but it really isn’t.

When the brake lever is pulled, it may seem like you’re applying pressure to the disc, but you’re actually opening a valve to allow fluid to flow downward from the reservoir. Since brake fluid is very viscous, it exerts pressure on the brake calipers with the help of the pistons which move to make contact with the disc and rub it. The more pressure from above, the more pressure is generated in the contact force between disc and brake pad and hence the force of friction makes the disc stop rotating and accordingly the bike stops.
