Master cylinder components:ππ
- Brake Fluid Reservoir: This holds the brake fluid, which is essential for the hydraulic brake system to function. It is usually made of transparent plastic to allow easy monitoring of the fluid level.
- Master Cylinder: The master cylinder converts mechanical force from the brake pedal into hydraulic pressure. When the brake pedal is pressed, it pushes a piston inside the master cylinder, which pressurizes the brake fluid.
- Brake Hose: These flexible hoses transport brake fluid from the master cylinder to the brake calipers at each wheel. They need to be durable and flexible to withstand high pressure and constant movement.
- Brake Pedal: The brake pedal is what the driver presses to activate the braking system. The force applied to the pedal is mechanically amplified and then transmitted to the master cylinder.
- Brake Pad: Brake pads are friction material pressed against the rotor to slow or stop the wheel. They are a wear item and need to be replaced periodically.
- Rotor: Also known as a brake disc, the rotor is a metal disc connected to the wheel hub. The brake caliper squeezes the brake pads against the rotor to create friction and slow the wheel.
