Raynal's Reflection

I have learned many things about the car brake. First of all I learned all about the components and the leverage. Also i have learned about the disc and drum brakes are. I have also learned about the friction of the brakes. Most importantly I have learned about what happens with the brake if the temperature changes. Car brakes is such an amazing topic to learn about. Hope all of you people enjoy!

Forrest's Reflection

Doing this project helps me to learn about what I have always wanted to learn car brakes. This is an incredible system because this connects to most of the topic we are learning now. The brakes are using the principle of pressure and compression. Hydraulic brakes uses pressure of liquids to help multiply the power of our legs to stop a car, and the air brakes uses compression of air to push the brake so it would stop the car/truck. This project helped me understand the pressure and the reversed order of pressure and that how it can help our everyday life and make it easier, and what seems ordinary can be one of the most important thing that we rely on for our transport.

Input and Output:

When you step on the foot the oil in the drum and being pushed down, and through that action it multiples the pressure so it will be able to slow down the discs, and there for stopping the car. For air brakes it works completely different from the hydraulic brakes. When the pedals are pushed an air pump pumps air into the side of the brake, and because air must go somewhere or else it will blow up, all the air is pushed towards the brakes to force it to slow down.

    

Affects Of Temperature On Brakes

Temperature has a big impact on brakes. If the temperature is cold the brakes might stick together and it will be hard to stop. If the temperature is hot the brake can lead to brake fading. Brake fading makes the brake bad and cant stop well. Brake fading is caused by hot weather. The hot weather changes the components and makes it hard to stop. 

Leverage

Leverage for the brake is the driver's leg controlling the brake pedal. The brake pedal is connected by rods and levers to the power booster. The driver controls with there leg pushing down on the brake pedal making it slow don or make it to a complete stop. The driver can control on how fast he wants to slow down. For example pressing down really hard will make it to a hard complete stop. But if the driver pushes it down slowly the car will come to a stop slowly. So the leverage of the brake is the pressure of the driver's leg pushing down at the brake pedal.

This is the brake power booster. The brake pedal is connected by rods
and levers to the power booster.

Friction Brake

A friction brake slows or stops the car by using kinetic energy into heat. There are two types of friction brakes: Drum brake and Disc brake. Drum brake is a brake that uses friction to cause the shoe or pad of the wheel to press against a spinning surface. Disc brake is used to stop or slow the rotation of the wheel.
