The master cylinder is a control device that changes non-hydraulic pressure from a driver’s foot into hydraulic pressure.in doing this, it controls another component called the slave cylinders located at the other end of the system.
As pistons passes along the bore of the master cylinder, this movement is translated through the master cylinder to a movement of the slave cylinder(s) through the hydraulic fluid. The pressure created by moving a piston toward the slave cylinder(s) forces the fluid evenly.
The most common cases of master cylinders uses are in brake system and clutch systems. In the brake situation,, the devices are cylinders found inside of brake calipers and/or break drums; these are called slave cylinders, and they push the brake pads towards a surface that turns with the wheel this could be a drum, or a disc most often referred to as rotor until the stationary brake pad(s) causes friction against that turning surface. In the clutch system, the device that is controlled by the master cylinder is called the slave cylinder this moves the throw out bearing till the high-friction component on the transmission’s clutch disengages. For hydraulic brakes and clutches alike, flexible high-pressured hoses or inflexible hard-walled metal tubing is often used however the flexible kind of tubing is still essential for a short length adjacent to each wheel. Whenever the wheel can move relative to the car’s chassis
There’s a reservoir above each master cylinder that supplies the master cylinder with enough brake fluids to avoid entrance of air into the master cylinder. Now almost all light trucks and passenger vehicles have one master cylinder for the brakes which has two piston but many racing vehicles, as well as some classic have two separate master cylinders, each with only one piston. Each piston in a master cylinder works like a brake circuit, and in the case of modern light trucks and passenger cars, usually a brake circuit are connected to a brake caliper or shoe on only two of the cars’s wheels, while the other brake circuit provides brake-pressure to power the other two brakes.
