BRAKES



BRAKING
Brake Pads

The braking systems of cars and trucks are made up of a number of parts, these parts transfers the driver's actions into the force that stops the vehicle, one of those brake parts is your vehicle's brake pads.

Brake pads play a key part, they are the component that applies pressure and friction to a vehicle's brake disc, (those shiny discs that you can often see just behind the wheels)

The pressure and friction applied to the brake disc is what slows and stops the wheel, and depending on how fast a vehicle's wheels are rotating and how much the vehicle weighs determine how much stress the brake pads endure.

A high quality BRAKE PAD is therefore vital to ensure the car is brought to a halt as quickly and as safely as possible, when you don't know what's around the next corner fit the best.

Brake Discs
Most modern cars have brake disc on the front wheels, some have discs on all four wheels, these in conjunction with brake pads do the actual work of stopping the car.

The brake pads squeeze the brake disc and friction between the brake pads and the brake disc slows the disc down and brings the vehicle to a stop. A moving car has forward motion (kinetic energy) and the brakes have to remove this energy from the car in order to stop it.

Brakes have to convert the kinetic energy to heat, the heat is generated by the friction between the brake pads and the brake discs. Many modern cars have vented discs, a set of vanes in-between the two sides of the disc, allowing air to pass through to provide more effective cooling of the disc.

Brake Drums

Brake drums work in a very similar way to brake discs, the brake shoes are pressed against the inner edge of the rotating drum creating the friction needed to bring the vehicle to a stop, many cars have brake drums on the rear wheels and disc brakes on the front.

Brake Drums generally have more parts than disc brakes and are harder to service but the reason for retaining drums at the rear is that a drum is more effective than a disc as a parking brake.

Brake Shoes

The brake shoe carries the brake lining, the brake lining is usually riveted or glued to the shoe, when the brake is applied, the shoe moves and presses the lining against the inside of the drum. The friction between lining and drum provides the braking effort, energy is dissipated as heat and the vehicle slows down.
