What is a Drum Brake?
A drum brake is a brake that uses friction by a couple of shoes or pads that press circle shaped drum is called drum brake. Nowadays heavyweight vehicle use this braking system for best results. For heavyweight vehicle it is more useful than disc brake. In this blog we will show you what is the components of a drum brake and how it's actually work.
Components of a drum brake:
There are many components in a drum brake system. Main components are brake shoes or pads, drum, master cylinder, returning spring, backing plate and lever also.
How does a drum brake works?
When the driver push brake padal down, master cylinder pressurized hydraulic fluid and this fluid goes to the wheel cylinder and push pistons outward. For that brake shoes expand and it friction by the drum which is rotating with wheels. This rubbing action reduces the rotation of drum which is coupled to the wheel. After it reduces the rotation of wheels vehicle stop running and when driver release brake padel, pressure of hydraulic fluid decreases. For that wheel cylinder back to his place and brake shoes are returned by returning spring. That's how a drum brake works. But how does a parking brake system works in drum brake system?
Parking brake or Mechanical brake system:
Parking brake system also called mechanical brake system. It actually works mechanically that's why it's called mechanical brake system. In this system it has an another component which is lever. Parking brake is connected with lever by a wire. When the driver pulls parking brake it also pull the lever by wire and lever press drum manually and it causes friction which stop the wheel rotation.
