Cara Kerja Rem Tromol Pada Motor

Summary

This video explains the mechanics of the rear drum brake system commonly used in automatic scooters. It covers the components inside, including the two brake shoes and the lever that moves them. The system operates by creating friction between the stationary brake shoes and the rotating drum, pushing the shoes outward to stop the vehicle. The video highlights the benefits of drum brakes, such as better protection from external elements, larger friction surface for stronger braking, and lower wear, making it ideal for heavy loads. It also details how the system works with simple, durable components.

Takeaways

• 😀 The rear brake system on automatic motorcycles typically uses a drum brake mechanism.
• 😀 Drum brakes are made up of two main components: the brake shoes and the lever that moves them.
• 😀 The drum brake mechanism operates through friction between two moving components: the drum and the stationary brake shoes.
• 😀 Unlike disc brakes, drum brakes use an outward motion to push against the drum, creating braking force.
• 😀 Drum brakes are more enclosed, protecting them from external elements like water and dirt, which improves reliability.
• 😀 The brake shoes of a drum brake are wider than disc brake pads, creating a larger friction area for better braking power.
• 😀 The larger friction area in drum brakes results in stronger braking performance, especially when carrying heavy loads.
• 😀 Drum brakes have a lower wear rate due to the larger friction surface, making the brake shoes last longer.
• 😀 The braking action in a drum brake is initiated by a cable that moves a lever when the brake lever is pulled.
• 😀 When the brake lever is released, a spring mechanism automatically returns the brake shoes to their original position, ready for the next braking action.

Q & A

What components are found inside the rear drum brake system of a scooter?

The rear drum brake system consists of two brake shoes and a lever to move them.

How does a drum brake work?

A drum brake works by using friction between two components: the drum, which moves, and the brake shoes, which are stationary. This friction slows down the wheel.

What is the difference between drum brakes and disc brakes in terms of friction mechanism?

In drum brakes, the friction causes the drum to push outward, whereas in disc brakes, the friction works by clamping the disc.

Why is the drum brake system considered safer from external disturbances?

The drum brake system is more enclosed, making it less susceptible to external elements like water or dirt, which can affect performance.

What makes drum brakes more reliable for heavy loads?

The wider surface area of the brake shoes in drum brakes provides a larger frictional contact area, making them more effective for vehicles carrying heavy loads.

How does the brake shoe's size affect the braking power in drum brakes?

The larger surface area of the brake shoe in drum brakes increases the contact area with the drum, which results in stronger braking power.

Why do drum brakes wear out slower compared to disc brakes?

The increased surface area in drum brakes leads to lower pressure per area on the brake shoes, causing slower wear compared to disc brakes.

What happens when the brake lever is pulled in a drum brake system?

When the brake lever is pulled, a cable moves the lever, which then activates a mechanism that pushes the brake shoes outward to contact the drum and initiate braking.

How do the brake shoes return to their original position after braking?

The brake shoes are equipped with springs, which automatically pull them back to their original position when the brake lever is released.

What is the main advantage of the drum brake system in terms of maintenance and cost?

Drum brake systems are more cost-effective and require less frequent maintenance due to their design, which results in slower wear and tear of the brake shoes.
