Brake pumps and master cylinders

Brake pump

On motorcycles, the master cylinder is responsible for supplying pressure to the brake system, allowing for effective braking. Brake pumps on motorcycles are usually divided into two types:

Piston pumps: they work by pumping brake fluid through a piston. These are more popular on motorcycles because they are simpler in design and easier to service.
Diaphragm pumps: operate on the principle of movement of a diaphragm that pushes brake fluid through the system. They are less popular on motorcycles because they are more complicated in design and more difficult to service.

Both types of master cylinders can be manual or automatic, depending on the motorcycle. Automatic pumps adjust the pressure to meet the needs of the braking system, while manual pumps require the motorcyclist to adjust the pressure.

Scooter brake pump

A scooter brake master cylinder, which is mounted on the handlebars, is a type of brake lever that is used to activate the scooter's braking system. It is usually connected to the brake caliper via a brake line, and when the lever is pulled, it applies pressure to the brake caliper, which in turn slows or stops the scooter's wheels.

A handlebar-mounted brake master cylinder, called a handlebar brake lever, is the most common type of brake lever used on scooters. This type of brake lever is convenient and easy to use because it allows the rider to control the brakes with a hand that is already on the handlebars. This type of brake lever is generally considered more responsive and easier to use than a foot-controlled brake lever.

It is also important to make sure the brake lever is in good condition, the brake cable and hose are in good condition, and the brake fluid level is at the correct level.

What is the difference between a manual and automatic master cylinder on a motorcycle?

In a manual master cylinder, the motorcyclist must adjust the pressure in the brake system himself, such as by adjusting the lever accordingly. In contrast, an automatic pump adjusts the pressure in the brake system automatically, so the motorcyclist does not have to worry about adjusting the pressure.

What symptoms can signal a defective brake master cylinder on a motorcycle?

Symptoms of a faulty motorcycle master cylinder can include a soft or spongy feeling when trying to brake, difficulty braking and a decrease in braking power. In addition, if the brake fluid level in the reservoir is low or there is a noticeable leak, this may also indicate a problem with the master cylinder.
