Electronic device controlling the hydraulic pressure in the braking circuit, to prevent the wheels from locking.
See antilock braking system (ABS) in : french | spanish
pump and motor assembly
Pump driven by an electric motor, circulating the brake fluid from the accumulator to the master cylinder.
brake pressure modulator
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
Set of electric wires transmitting the signals from the sensor to the electronic control unit.
wheel speed sensor
Device sensing the rotation speed of a wheel and transmitting that information to the control unit.
electronic control unit
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
Reservoir supplying the master cylinder with the fluid that transmits pressure to the brakes after the driver presses the brake pedal.
braking circuit
System of tubes containing a fluid that activates the brakes when they come under pressure from the pedal.
brake pedal
Lever that the driver presses with the foot to activate the brake system.
brake booster
Mechanism amplifying the force exerted by the driver on the brake pedal.
master cylinder
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
Braking mechanism comprising a disc attached to the wheel, whose rotation is slowed down when the brake pads exert friction on it.
