When the car is being driven fast, as soon as the electronics detect excessively light loads on wheels on the inside of a bend, the
hydraulics of Electronic Stabilisation Program (ESP) apply
brake pressure to this wheel to restore optimal traction.
A leak in the
hydraulic system can cause the Ford
brake caliper to operate less efficiently, leaving it without enough fluid pressure to cause the
brake pads to move into contact with the
brake disc, or to retract away from the disc
when the
brake is released.
Both
brake types use a
hydraulic braking system as well as a
brake pad or
brake shoe to create friction and cause a vehicle to stop
when the driver applies pressure to the
brake pedal.

When the ECU determines that friction
braking is needed, the dual
hydraulic master cylinder pumps
brake fluid through the system.
Just like the gearbox, it works silently but efficiently in the background so you don't really know
when the system swaps between the
hydraulic and regenerative
braking phases.

When the driver applies the
brake pedal, a signal is sent to the vehicle's Electronic Control Unit (ECU), which determines the appropriate amount of
braking force to assign to regenerative
braking through the electric drive motor and to the
hydraulic friction
braking system.
Hudson automobiles used an unusual hybrid
hydraulic - mechanical dual -
brake system which operated the rear
brakes through the otherwise conventional mechanical parking
brake system
when a failure of the
hydraulic system allowed the pedal to travel beyond its normal limit.
When a tire begins to lose traction, the sensor sends a signal to the electronic control unit, which instructs the
hydraulic modulator to reduce the amount of

Additionally
when the
hydraulic wheel
brakes are subject to high loads, the controllable cool - air inlet opens and releases two ducts which channel the cooling air into the front wheel arches to the
brakes.
A pressure sensor in the ESP
