Vehicle Maintenance: An introduction to brake safety
Brakes are a wearing component of your vehicle. We recommend checking them regularly to stay safe on the road.
How brakes work and the different types of vehicle braking systemsAll brake systems use hydraulic pressure to function; a system of fluid-filled pipes that can create and multiply force as it transmits it from one place to another under pressure (like a syringe). When the brake pedal of a vehicle is applied it forces the fluid under pressure through a series of cylinders to the braking system within each wheel.
This pressure generates the force and friction needed to operate the brakes to slow and stop the vehicle. Without the hydraulic system, simply pushing your foot onto the brake pedal would not produce the force needed to bring a fast-moving vehicle to a stop.
These work in a similar way to brakes on a bicycle. When a vehicle driver pushes on the brake pedal, a pad made of hardwearing material clamps onto a spinning brake disc. The disc is attached to a moving wheel hub and when the pad rubs against it, causing friction, the hub rotation is slowed to the point where the vehicle stops. Today disc brakes are increasingly popular as they have greater resistance to fading.
These work in a slightly different way, instead of the brake pad rubbing on a disc; they have a hollow drum that’s attached to the wheel. Inside the hollow drum is a pair of curved brake ‘shoes’ made of hardwearing material. When the brakes are applied, the shoes are forced to expand into the hollow drum and push out, causing friction that slows and stops the vehicle. Some vehicles have drum brakes only on the rear and disc brakes on the front, because under braking, weight is transferred to the front of the vehicle, so requires stronger disc braking.
HandbrakeA car’s handbrake applies the two rear brakes (disc or drum) in a slower, less forceful way to lock the cars brakes and keep the car stationary. The handbrake on older cars is usually a lever located between the 2 front seats. On many newer cars the handbrake, also known as the parking brake, is a button that operates the brake electrically.
