Motorcycle cylinder master

What is the role of the master cylinder?

The main role of the brake master cylinder in a motorcycle is to convert the force exerted on the brake handle into hydraulic pressure.

This pressure is then transmitted to the brake calipers, which use this pressure to tighten the brake pads against discs or drums, which makes it possible to slow down or stop the motorcycle.

The master-cylinder therefore plays a crucial role in the safety of the motorcycle by allowing the driver to brake effectively.

What is the role of the motorcycle clutch lever?

The motorcycle clutch lever is a mechanical component that allows couple and decouple The motor of the motorcycle transmission.

It is located on the handlebars, and the driver uses it to activate the clutch. When the driver presses the clutch lever, he moves the engine from the transmission, which allows change speed Or put the motorcycle in a standstill.

When the driver releases the clutch lever, the engine is again coupled with the transmission, which allows the motorcycle to resume its march.

The clutch lever is therefore an important element for the proper functioning and driving of the motorcycle. The master cylinder motorcycle clutch can also be hydraulic as for braking.

What are the types of cylinder master?

There are two main types of brake master cylinder for motorcycles:

• The axial master cylinder (Standard because the most widespread): A piston that pushes the brake oil to the brake calipers. It is generally used on small and medium -displaced motorcycles, as it is simple to make and maintain. It is coupled with axial brake calipers as well.

• The Master-cylinder Radial : which are used on high -end motorcycles, they are lighter, more compact and more aesthetic. They also have a better distribution of pressure and greater braking power.

There are also adaptive masters that are equipped with a system that allowsadjust automatically the distance between the brake handle and the lever. It also allows you to adjust the sensitivity braking (more or less "biting"). This system is used to facilitate the use of the bike for drivers of different sizes and for Improve driving comfort And so the security.

How to distinguish the type of braking on my motorcycle (radial or axial)?

These thermal baths are identical to the name of the brake caliper. You have to take your wheel as a landmark. In thewheel axis So said "axial" and in the sense of wheel So says "radial". If you want to know more, you can consult our blog articles.

Why change the master cylinder?

There are several reasons why it may be necessary to change the brake master cylinder on a motorcycle:

• Normal wear and tear: The master-cylinder is a mechanical component that undergoes considerable forces when the driver presses the brake handle. Over time, parts can wear out and become less effective. If you notice that your motorcycle does not brake as well as before, it is possible that the master cylinder is worn and that it is necessary to replace it. On some high-end masters, there are kits allowing to replace only the failing internal organs.

• Oil leak: The master-cylinder is filled with brake oil which is used to transmit the brake handle pressure to brake stirrups. If you notice a brake oil leak around the brake handle, it is possible that the master-cylinder seal is damaged and that it is necessary to replace it.

• Performance improvement: Some drivers wishes to improve the performance of their motorcycle and replace the master cylinder for a more efficient model which allows better braking power and better distribution of pressure.

It is important to note that these are general cases, it is therefore important to consult a mechanic to check the condition of your master-cylinder and decide if a replacement is necessary.

How to choose the right cylinder master?

There are several factors to take into account when choosing a new brake master cylinder for your motorcycle:

• Compatibility: Make sure that the master motorcycle brake cylinder you buy is compatible. It is important to check the displacement of your engine and the type of braking (disc or drum) to ensure that the new master cylinder is compatible.

• Size : It is important to choose a good-size master cylinder for your motorcycle. The higher the displacement of your engine, the larger the master cylinder must generate enough pressure to brake effectively. Be careful you must always keep homogeneity with the stirrup (s).

• Kind : There are different types of master cylinder, such as the master-cylinder with radial or axial piston it is important to choose the right type according to your needs and preferences.

• Brand : It is important to choose a good quality master cylinder to guarantee reliability and sustainability.

• Facility : It is important to check whether the installation of the master-cylinder is easy and the necessary tools are included. It is also important to check whether the installation instructions are clear and easy to follow.

It is important to note that these criteria are general and it is important to consult a mechanic to verify which master cylinder is best suited to your motorcycle. It may also be useful to consult biker forums and user reviews for information on the different models available.

How to purge the master cylinder? (pay attention to the brake and clutch contactors)

The Master Motorcycle Master Purge is a process which consists in eliminating the air present in the braking system. This is necessary when air has entered the system, which can cause malfunction or reduction in braking power. Here are the general steps to purge a brake master cylinder:

1. Prepare the necessary equipment : You will need a brake bleeding kit, clean brake oil and a tool to loosen the brake fittings.
2. Locate the brake master cylinder: the brake master cylinder is generally located on the handlebars of the motorcycle, it is often covered with a cache.
3. Loosen the brake purges : Use the appropriate tool to loosen the brake purgeurs located on the brake master cylinder and on the caliper. Be ready to collect the oil that will flow when you loosen the fittings.
4. Purge the system : Use the brake bleeding kit to purge the system. Depending on the kit, it may be necessary to press a pump to suck the air or press the brake lever to get the air out.
5. Check the oil level : When the air is evacuated, fill the master-cylinder with clean brake oil to the appropriate level. During the operation, keep liquid in your jar. The type of oil to be used is generally written on the brake tank cap.
6. Reinstall brake fittings : Tighten the brake fittings again and check that the oil leak is absent.
7. Test braking : Test the braking to make sure it is working properly. It is important to do this on a safe ground and with a moderate speed. You can also wait until several hours to check if air bubbles are still present in the circuit. These will go up and your lever will be "pout", it will then be necessary to start again.

It is a major organ in the safety of your motorcycle. We advise you to call on a professional. You can also consult on YouTube A large number of explanatory videos.
