Today, we’re going to talk about the part of your car that you use numerous times a day and that, if it broke, would probably kill you or seriously hurt you.
Your brakes are what I’m talking about.
Schedule cheap car brakes repair every month or two at least. So, where can you repair your brakes for the least amount of money? Regular maintenance will be reasonably priced, but a replacement project will undoubtedly cost more.
Making heat out of motion
The science behind brakes is pretty easy to understand. To divert down or stop your automobile, the friction between your brakes and the wheels changes the kinetic energy of your wheels’ movement into heat energy. Once the brakes have turned all the energy of the tyres into heat energy, your car stops.
How a car’s brake system works:
1. Brake pedal
It’s the lever that your foot presses to slow and stop the car.
2. Brake booster
Most cars today have something called power brakes. When you amble on the brake pedal, the power brake system increases the force that is sent to the remaining portion of the brake pedal. What helps make power brake pads work is the brake booster.
3. Master cylinder
If you’ve ever looked under your car’s hood, you’ve probably seen the cylinder but didn’t know what it was called. The master cylinder is the storage of brake fluid. Your car’s brake fluid goes to each wheel through brake lines. Once you step on the pedal, the energy is enhanced by the brake booster. This moves a piston within the cylinder, which forces transmission fluid out of the cylinder and then into the brake pads that go through each wheel. The brake pads on your tires are then turned on by the fluid.
4. Brake lines
Brake lines are metal tubes that go from the cylinder to the 4 brakes on each wheel of your car. The brake fluid gets to a brake drum or a disc brake through the brake lines. The brakes work because of the force from the fluid.
5. Drum brakes
Since 1900, cars have had drum brakes, and they are still used today. Drum brakes are put on wheels. Inside the drum are two pads called brake boots that can handle the heat. When you step on the brake pedal, the liquid is pumped into the wheel cylinder of the drum brake. The fluid then moves usually two pistons within the wheel cylinder, which forces the brake shoes outside and pulls them against the brake drum. The pads slow down the drum, and since the drum is connected to the wheel, it also slows down the wheel.
6. Disc brakes
One bad thing about drum brakes would be that they don’t need anything else to work. The heat that is made when the brake pads rub together stays within the drum brakes. Drum brakes can become very, very hot in tough conditions and when they are used a lot. If the brakes become too hot, they won’t be able to make enough friction to slow down the car. Engineers came up with the disc brake to solve this problem.
So let’s put the brake system parts together
You put your foot on the brake. This turns on the brake stimulant, which makes the brake pedal’s force stronger. This force moves to the cylinder. The master cylinder has a piston that pushes brake fluid to each wheel through brake lines.
If a tire has a drum brake, the fluid flow will move a piston in the cylinder, which will move a whole other nozzle, which will push the brake pads against the brake drum. The car stops or slows down. When you let go of the brake pedal, the braking system fluid will flow back into the cylinder, and the brakes will release.
If the tire does have a disc brake, the brake fluid will move a piston that squeezes brake pads against a disc, or rotor, attached to the shaft. This slows the car down. When you let go of the brake pedal, the wheel fluid flows back into the cylinder. This makes the callipers on the brake disc open up again.
In short, that’s how the brakes on your car work.
