Inside this article, we will talk about what is disc brake and what is disc brake working principle. Friends, most people prefer disc brake bikes. Because it is very good to see. And drum brakes are not visible from being inside the tire. While disc brakes remain outside the tire and are easily visible. Which adds to the beauty of the bike. Often you have noticed that there are disc brakes inside expensive vehicles. And the bikes that come inside the low price. In them, the company only provides drum brakes.

While disc brakes are provided only in the front tires inside some bikes. This is done because if the rear tire has disc brakes, it will not be easy to remove and set it.

However, it is not that disc brakes only work to enhance the beauty of the bike. They also have many advantages. Below we will talk about their benefits. By the way, you must have seen disc brakes. If not, then you must have missed seeing the picture.

The use of disc brake is nowadays used in all types of trains. Disc brakes are being used even inside the train. There is a rotor inside the disc brake. Which is slowed down with the help of calipers. However, heat is produced inside this method. Which is spread. Hydraulically activated disc brakes are the most commonly used form of brake for motor vehicles, but disc brakes can be applied to any rotating shaft.

Design of disc brake

First of all, in 1890, disc time brake designing started in England. Then in 1902, Lanchester Motor Company designed brakes that looked similar to a modern disc-brake system. Before World War II, the airplane featured disc brakes that were successful, and even the German Tiger tank was fitted with a disc in 1942. Disc brake brakes appeared well within 1953.

 Disc brakes were used inside the man's race. The Jaguar racing team won by using cars equipped with disc brakes, as rivals were using only drum brakes. And his performance was poor.

The first caliper-type automobile disc brake was patented by Frederick William Lanchester at the Birmingham factory in 1902 and used inside Lanchester cars. Within this time copper was used inside the disc brake.  But the use of copper inside the disc brake could not be very successful because the copper did not work properly due to the rough terrain and dust turbulence. In Britain, the Daimler Company used disc brakes on their 1939 Daimler Armored car, disc brakes made by the Girling Company were also used in heavy loads.

In Argus Motörn, Germany, Hermann Klu (1912–2001) patented disc brakes in 1940. In which he introduced disc brakes for every type of shaft. American Crosley Hot Shot is often credited with the first production disc break. American Crosley Hot Shot made a car inside 1950 AD. Inside of which the disc brake was fully used.

However, this system could not become popular as it used to deteriorate due to excessive corrosion during the rainy season. They could be used easily within normal days. Disc brakes were introduced by Chrysler from 1949 to 1953 using a special disc system. The system used twin expanding discs to hold the wheel inside the cast-iron brake drum by rubbing it.

Also, the four-wheel disc brake was built by the Auto Specialty Manufacturing Company of St. Joseph, Michigan, under the patent of inventor HL Lambert and first tested in 1939 at Plymouth.

The first use of the disc brake was done inside the Formula One car in 1951 AD. Disc brakes were then used in the Jaguar C-Type racing car in 1953. These proved to be very helpful in winning the race.

Disc brake production

1. The first mass production of modern disc brakes was used in 1955. Which included the production of several types of disc brakes.
2. Triumph showcased the 1956 TR3 Disc Brake to the public, the first production cars with a Girling front-disc brake were made in September 1956.
3. There is a high demand for disc brakes inside sports cars as it is very important for them to perform well.
4. Between 1989 and 2005, the manufacture of brake discs went mainly to China.

First bike with disc brake

MV Augusta was introduced in 1965 AD by applying a desk brake inside one of its expensive bikes. They introduced disc brakes on the front tires of the bike. After that Honda introduced the CB750 bike. Inside which a disc brake was used. And after that, mopeds and scooters all started using disc brakes.

What is a hydraulic braking system

The hydraulic braking system is used inside the Friends disc brake. So before getting to know about disc brakes, we get to know about the hydraulic braking system. ब्रेक Brake wire is connected to a piston inside the hydraulic brake system.

The piston moves inward when you press the brake. And next to the piston, the oil pump is filled and presses the pad inward and presser. The pad stops the rotating rotor. There is an oil tank above the piston. If you have noticed on bikes with disc brakes, then their brakes have a tank. There is oil inside it. And when pressing the brake, then it forces the oil pad and brakes.

Disk Brake Working Principle

The disc brake mechanism is almost the same in both bike and car and inside the car. So let's understand in a simple way how disc brakes work. Most of the disc brakes are like the brakes of your cycle. There are calipers inside the bicycle. They stick fast on the ream. And doing so stops your cycle. In a way, it is friction between the rim and the calipers.

There is kinetic energy inside a moving car. And to stop the car, the kinetic energy has to be removed from the car. Then it is possible to stop the car. And the brakes do it. When you stop the car, friction between the brake pad and the disc is created. The disc brakes are vented inside the car.

There is a caliper inside the disc brake. Disc brakes are connected to paid calipers. It is moveable. And moves when applying brakes. Also, the disc brake pad works by sticking with the rotor. Disc brakes are fitted with pads to reduce friction. The hub is attached to the rotor. And next to that, Viheel is attached. And is tightened with a nut bolt. Also, the calipers are attached to the piston. The piston works to move the calipers.

In contrast, two or four pistons were used inside old cars. But now this system has been abolished. Now only one piston is used. And he is also more reliable. Mostly inside four-wheel carrying disc brakes are used. It also has an emergency brake. It is quite different from the primary brake. And a cable is used to activate it.

While some cars have a disc brake at the back along with a disc brake at the rear. Which is active only inside the emergency condition.

1. Disk brake pads

The disc brake pad is attached to the calipers. The pad is usually a piece of metal. Your brake pads are fitted with a special material that serves to apply car brakes and reduce friction in the rotor. You can see that the brake pad is replaced if the brake material is damaged. There is also a sufficient amount of friction material inside the brake pad and manufacturers also warn to keep it inside a certain amount. If its thickness is reduced, it is necessary to replace the brake pad.

The brake rotor has a short life span due to friction with the pad. And sometimes the rotors go bad. Their flatness is gone. This causes a shiver in stopping the break. It requires machining of the rotor.

However, the machining of the rotor should not be done every time. Because it reduces its thickness. And it is not advisable to use a rotor of less than standard thickness. When one of the pads seizes inside the caliper bracket, it can cause a number of problems, such as overheating and noise.

2. Brake disc

The disk is mounted on the hub. And the space between the disc and the hub must be clean. Otherwise, the disc brake capacity is affected. In addition, many times when the disc is rusted, the brake cork capacity is affected. There is also a problem with the disc or rotor. That it is hot when you apply the brake. And by doing this, slowly the thickness of the disc starts changing. Meaning the disk becomes thinner than anywhere else. If the disc brake has cracked or has become damaged, it is better to replace it.

a) Air vent

You might have noticed that modern discs are ventilated. This is because when there is friction between the pad and the disc, then a large amount of heat is produced inside. And the ventilated disc provides cooling to the disc by reducing this heat.

3. Brake calipers

Front brake calipers are mounted on the steering knuckles. Rear calipers are bolted to the rear spindle. Brake pads are attached to the calipers. And with the help of calipers, when the brake pads are attached to the rotor, the heat is generated during the time the brake is applied. Which the calipers also have to face. When you change the rotor, you can also check the calipers. If they are spoiled, they should also be replaced.

Types of disk brakes

There are many types of disc brake systems. For example, two pistons are used inside some disc brakes. So some have only one piston used, besides two couplers.

1. Single piston type disc brake

Friends, these are common disc brakes. And only one piston is used inside them. We have told you in detail above about single piston disc brakes. When you press the brake lever, the oil pushes the piston. Causing the brake pads to shrink and stick to the rotor. Whose wheel stops running.

2. Double piston disc brake

Double pistons are two-piston inside the disc brake. And the rest of the work is like a normal disc brake. Two calipers are also used here. Usually, when the brake lever is pressed, the brake pads stick to the rotor due to the piston pressure.

2. 2 calipers type disc brake

Friends are also like common disc brakes. But its special thing is that there are two calipers on a disc inside it. And they work to stop the car. This type of disc system is used especially to prevent heavy vehicles. Because they provide a good braking system.

Type of disc brake according to pressure

Friends, we told you several types of disc brakes above. They were types of disc brakes based on the structure of the disc brake. But most common disc brakes are mechanical and hydraulic disc brakes.

1. Mechanical disc brake

Most of them come inside bikes and bicycles which are quite affordable. Fluids are not used inside them. Because of this, they fall within the low coast. And it is very easy to maintain them. If you want to avoid extra expenses of disc brake, then you can use a mechanical disc brake. But they do not give you more control like hydraulic disc brakes.

2. Hydraulic disc brake

‌‌‌Hydraulic disc brakes are the most common type of braking. What happens inside is that the hydraulic fluid is filled in the cables. This type of disc brake is most commonly used. The control of these breaks is good. But maintenance is more. The cable is replaced every 6 months. In addition, it is also necessary to change the fluid. So that it can maintain its ability to bear hot.
