Brake Master Cylinder

The master cylinder is an essential device which helps convert the force from the driver's foot on the pedal to hydraulic pressure. The pressure makes the piston in the calipers force the brake pads to clamp down the brake rotor and drums. Common vehicles usually use the master cylinder in brake and clutch systems and each master cylinder has a reservoir as well as pistons to help the braking system.

Brake and clutch systems

The brake system is operated by the cylinder inside the calipers, and they push the brake towards the rotor causing friction. The clutch system is a device which has the master cylinder function with the use of the slave cylinder. It usually has the throw out bearing move, so the transmission's clutch separates from the flywheel.

Brake fluid reservoir and pistons

The reservoir is used in each master cylinder as it helps store enough brake fluid to prevent air from entering the master cylinder. Also, the primary piston can generate enough pressure to allow the secondary piston to bottom the cylinder bore. By then the main piston will have enough pressure to make the brakes function.

Common issues with a brake master cylinder

A faulty brake master cylinder can lead to fluid leaks, air infiltration, and can cause corrosion within the master cylinder.
