What ABS does
An anti-lock braking system senses when a wheel is about to lock up under braking and briefly reduces brake pressure. This helps you keep steering and stability when you brake hard or on a slippery surface. You may feel a pulse in the lever or pedal when it works.
What traction control does
Traction control detects a rear wheel that is starting to spin and reduces engine power to restore grip. Many systems have several levels, and some can be switched off. It is useful on wet roads, loose surfaces and when you open the throttle in a bend.
What they cannot do
- They cannot create grip that the tyre and the road do not have.
- ABS does not shorten the stopping distance in every situation, and on loose surfaces it can lengthen it.
- They do not replace good braking technique, tyre care and smooth throttle control.
How to use them
- When braking hard, squeeze firmly and keep the pressure. Do not release because you feel the pulse.
- Read your manual, learn what the dashboard lights mean and practise in a safe place.
- Keep tyres, brake pads and fluid in good condition. See braking technique and brake fluid.
If an ABS or traction control warning light stays on, the system may be switched off. Have it checked by a workshop.
