The rear wheel get most effort

The brake force is reduced at rear when loaded

The brake force is increased at rear when loaded

The force is distributed 60:40 across rear axle

sensing the speed and rate a driver presses bake pedal

detecting vehicle in front has stopped

detecting motion in front of vehicle

the safing sensor signals it

Electronically applying handbrake

On Hill starts

extra hydraulic pressure, to wheels with most grip

flashing a worning on brake lights

Cable type

Caliper type

Hydraulic type

Gear type

Static friction needs to be greater than kinetic friction

Kinetic friction needs to overcome static friction

We use a low torque gear

We use a high speed gear.
