The brake pedal is a component in the brake system that is used by the driver to brake. The function of the brake pedal plays an important role in the brake system. The pedal height must correspond to the specified height. If it's too high, the driver will take longer to move his foot from the gas pedal to the brake pedal, which can cause braking to be delayed. Vice versa, if the brake pedal position is too low, the reserve distance will be reduced and the braking force will be insufficient.
The brake pedal must also have sufficient free travel. Without this free movement, The master cylinder piston will always be pushed out and will cause the brakes to work continuously. This is due to hydraulic pressure that occurs in the brake system. Besides that, There must be sufficient reserve distance when the brake pedal is pressed so that braking can run smoothly.
Drum Brakes
Drum brakes are a type of brake that is most often found in vehicles such as cars and motorbikes. There are several components to this type of brake, like brake linings, cam, and the drum itself.
The function of the brake pedal when pressed on a drum brake is to create cam push the brake pads outward. Furthermore, The outer side of the brake lining will press the drum so that braking can occur. When the brake pedal is released, The brake lining will be pulled back in by the spring to return to its original position.
Disc brakes
As the name suggests, The main component of this type of brake is a disc that is attached to the wheel. Apart from discs, there is also a caliper component with a piston in it which works with the help of hydraulic lubricant pressure.
When the brake pedal function is operated, Hydraulic lubricant will push the piston in the caliper to clamp the disc. The friction that occurs between the two will automatically carry out the braking process, or slow down the vehicle.
When compared, Disc brakes have a number of advantages compared to drum brakes. One of them is the ability to maintain a working temperature that is not too high. Therefore, The braking process can be more stable.
Parking Brake
The parking brake or hand brake has different functions, its existence is not designed to stop or slow down the vehicle. As the name suggests, The parking brake is used to keep the car from moving when parked. even so, Its existence can be considered as a backup brake when the main brake really doesn't work.
In certain cases, Parking brakes are also needed for cars with manual transmission when stopping and going uphill. Most parking brake operations are mechanical. When the brake lever is pulled, there is a cable that operates the rear brake. On the lever there are teeth which are useful as a locking mechanism.
