Brakes are a normal wear item for any vehicle and will eventually need replacing. Many factors affect brake wear, like driving habits, operating conditions and vehicle type. When to book an appointment:

Brakes work by creating friction to slow and stop your vehicle. Every time you depress the brake pedal, the brake shoes or pads rub against the drums or discs, causing wear. So it's essential to have your brakes inspected regularly -- usually every six months or 10,000 km.
Most disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. This brake wear warning sound means that soon the brakes will not work well. Call to have your vehicle serviced. Continuing to drive with worn-out brake pads could result in a costly brake repair.
You may need to have your brakes inspected if: You hear noises when applying pressure on the brake pedal Your vehicle pulls to one side when braking Your brake pedal feels different than normal or if you've noticed any change in the way your vehicle brakes The parking brake doesn't work The dash brake light or ABS light stays on

We all know that pushing down on the brake pedal slows your vehicle to a stop, but how does your vehicle transmit the force from your foot to the wheels?
When you step on the brake pedal, you are actually pushing against a plunger in the master cylinder, which forces the hydraulic brake fluid through a series of tubes and hoses to the braking unit at each wheel. The difference between drum and disc brakes
For drum brakes, the hydraulic brake fluid is forced into the wheel cylinder, which then pushes a set of brake shoes against the inner surface of a rotating brake drum. The rotating drum is connected to the wheel and friction causes it to slow down and stop.
For disc brakes, the hydraulic brake fluid flows into a piston, which presses an inboard pad against the rotor. At the same time, the caliper, which holds the piston and brake pads, presses the outboard pad against the rotor. The pads then squeeze the rotor, which is attached to the wheel, forcing your vehicle to slow down or stop.
