antilock braking system (ABS)![click to hear](/images/speaker.jpg)
Electronic device controlling the hydraulic pressure in the braking circuit, to prevent the wheels from locking.
pump and motor assembly ![click to hear](/images/speaker.jpg)
Pump driven by an electric motor, circulating the brake fluid from the accumulator to the master cylinder.
brake pressure modulator ![click to hear](/images/speaker.jpg)
Hydraulic unit fitted with electric valves that, depending on the signals received from the electronic control unit, adjusts the pressure in each wheel cylinder.
sensor wiring circuit ![click to hear](/images/speaker.jpg)
Set of electric wires transmitting the signals from the sensor to the electronic control unit.
wheel speed sensor ![click to hear](/images/speaker.jpg)
Device sensing the rotation speed of a wheel and transmitting that information to the control unit.
electronic control unit ![click to hear](/images/speaker.jpg)
Device that, as a result of signals received from the wheel speed sensor, controls the brake pressure modulator to give the optimal hydraulic pressure.
brake fluid reservoir ![click to hear](/images/speaker.jpg)
Reservoir supplying the master cylinder with the fluid that transmits pressure to the brakes after the driver presses the brake pedal.
braking circuit ![click to hear](/images/speaker.jpg)
System of tubes containing a fluid that activates the brakes when they come under pressure from the pedal.
brake pedal ![click to hear](/images/speaker.jpg)
Lever that the driver presses with the foot to activate the brake system.
brake booster ![click to hear](/images/speaker.jpg)
Mechanism amplifying the force exerted by the driver on the brake pedal.
master cylinder ![click to hear](/images/speaker.jpg)
Mechanism composed of a cylinder and pistons that converts the mechanical force of the brake pedal into hydraulic pressure that is transmitted to the brakes.
disc brake ![click to hear](/images/speaker.jpg)
Braking mechanism comprising a disc attached to the wheel, whose rotation is slowed down when the brake pads exert friction on it.
accumulator ![click to hear](/images/speaker.jpg)
Device temporarily holding the hydraulic brake fluid while the modulator lowers the pressure.
