A brake is an object or device used to apply force to a moving object in order to reduce its motion and bring it to a halt. Brakes used on vehicles commonly bring a moving surface into contact with a stationary surface to generate friction, which slows and eventually stops the vehicle. The brakes used on cars at the beginning of the 21st century are usually either disc or drum brakes, with some manufacturers choosing a combination of the two.

Drum

The drum brake was the first new method of braking introduced in the late 19th century with components such as the brake shoes housed in a drum that spun with the wheel. When the brake pedal of a motor car is depressed, the brake shoes are forced against the drum slowing the wheel and the car.

Disc

Disc brakes were introduced in the 1970s as a way of increasing the efficiency of braking on cars used for racing, which over the subsequent years has trickled down to cars used for everyday purposes. A small caliper holds two brake pads, one on either side of a rotor which is attached to the wheel. When the brake pedal is depressed, the caliper clamps the two brake pads to the rotor creating friction and heat that slow the wheel.

Brake Fluid Level

The brake fluid container has “MIN” and “MAX” marks on it. The fluid level in the brake fluid container should not be lower than “MIN” mark, normally it should be close to “Max” mark. The brake fluid container should not have any leaks. If the brake fluid level is low, this might be an indications that brake pads are worn out. Another possibility, there might be a leak in the brake system. Either way, if you find that brake fluid level is low, have your car inspected as soon as possible, in some cases a car may be unsafe to drive.

Symptoms Indicating A Brake Problem

 

We cannot list all possible symptoms. If you suspect you have a problem with your brakes, have your car inspected as soon as possible. Below are just a few most common symptoms that indicate a brake system problem:

  • brake warning light comes on while driving
  • brake fluid level is low
  • ABS warning light comes on while driving
  • the vehicle pulls to one side during braking
  • the brake pedal pulsates and (or) the vehicle vibrates during braking – (mostly you can feel it from the steering wheel)
  •  the brake pedal is too hard or too spongy
  • the brake pedal goes down too far
  • any kind of noise while braking
  • (screeching, squeaking, grinding)
  • the brakes drag
  • (the car does not roll freely)
  •  smell of burnt brakes
