Understanding How Car Brakes System Works

It is common knowledge that the brakes are what stop cars. People rely on these brakes to stop their vehicles when needed. But most people need to learn how their disc brakes or brake pads work. When you use a car service regularly, ask them to take care of your brakes and teach you the mechanics of how your car’s brakes work.

The first part is the brake pedal that you press to stop the car.

The brake pedals are made of strong steel and work on the principle of a lever, and this lever transfers the force of pressing the pedal with your foot to a part called the “Master Cylinder.” There is also an electrical switch on the pedal that turns on the brake lights; pressing the brake will turn on the brake light at the rear of the car.

When depressed, the pedal transmits force to the master cylinder via a push rod. Master cylinders are reservoirs for storing brake fluid and also contain a piston. This piston compresses the brake fluid into the rest of the brake system through the brake lines. These pipes are usually made of copper alloys, a common mistake found during the annual technical inspection.

Most cars these days have four-wheel disc brakes, but older cars have drum brakes on the rear wheels. Pressure from the master cylinder is then transferred to the piston in the brake calipers. The pressure then applies force from the caliper to the brake pads against the brake discs, thus bringing the car to a stop. Read more at https://www.pedders.com.au/.

Brake pads are essential and need to be checked and replaced regularly. The pads are made to take a lot of heat and pressure to handle a modern car’s speed and stopping distance. Brake pads are made of metal and an organic compound to manage these conditions. Older motorists will remember that brake pads were once made with asbestos compounds, now prohibited by law due to cancer-related health and safety concerns.

Brake drums and discs are usually made from high strength steel or cast iron; they should also be checked regularly for wear and can warp over time, causing bad vibrations and poor braking. Brakes are best left to professionals and should be checked at every service interval. The performance of your brakes is tested at every service, but as long as the test doesn’t include a visual inspection, it makes sense if you did.


Many customers don’t know they have a brake problem until they hear a very loud squeal, at which point a lot of damage has been done. It is always best, as stated above, to check your brakes regularly and ensure that the parts being installed are quality from a reputable shop or service center.
