Hydraulic brakes system
A typical brake system consists of disk brakes in front and either disk or drum brakes in the rear connected by a system of tubes and hoses that link the brake at each wheel to the master cylinder.
When the driver steps on the brake pedal, he is actually pushing against a plunger in the master cylinder, which forces brake fluid through a series of tubes and hoses to the braking unit at each wheel.
• Disk Brakes (at front and rear) fluid from the master cylinder is forced into a caliper where it presses against a piston. The piston squeezes two brake pads against the rotor which is attached to the wheel, forcing the vehicle to slow down or stop.
• Drum Brakes (at rear) fluid is forced into the cylinder, which pushes the brake shoes out so that the friction linings are pressed against the drum, attached to the wheel, causing the vehicle to slow down or stop.
