Observation, anticipation and generous following distances should make the need for emergency braking rare. Keep your skills sharp by practicing emergency braking, when the road is clear ahead and behind.
Better still, practice off the highway and away from other vehicles. Occasional hard braking also stops pads and disks from glazing, maintaining maximum effectiveness.
You need to look for an escape path that will allow you to brake as hard as possible and avoid obstacles. Don’t get fixated by the source of danger - head around it.
Overall technique is just like normal braking but there are a few differences:
Having avoided one accident, make sure you don’t get involved in another. Check your mirrors and surroundings, then tap down the gearbox before riding away.
ABS can be a lifesaver in emergency braking, countering a locked wheel and allowing the rider maintain some control. But it can’t beat the laws of physics - you’ll still need distance to stop and you can still slide off in a corner.
Linked braking systems are usually combined with ABS to apportion braking forces between both wheels. Without ABS, linked systems can be prone to rear-wheel lock up. In low-speed manoeuvring, when you really only want the back brake, be very gentle on the pedal with a linked system. Some of the latest systems decouple at walking pace, earlier versions do not.
