Rem Blong, Ternyata Ini Biang Keroknya

Summary

This video script delves into the fearsome issue of brakes failing in vehicles, particularly focusing on hydraulic brake systems. It explains how hydraulic brakes use fluid to transfer pressure from the brake lever to the caliper, which then squeezes the brake discs. The script discusses the common problem of air entering the hydraulic system, known as 'brake wind', which can occur when the motorcycle's position is not always level, especially during turns. This can lead to air bubbles forming in the brake fluid, reducing the effectiveness of the brakes as the pressure is used to compress the air instead of pushing the brake caliper's pistons. The video aims to explore what happens when this issue arises and its impact on the braking system.

😨 Fear of Brake Failure in Vehicles

This paragraph discusses the fear of sudden brake failure while driving. It introduces the topic of the video, which is to explore what happens in the braking system when the brakes fail. The video will focus on hydraulic brakes, which use fluid or brake oil to transmit pressure from the brake lever to the caliper, which then squeezes the brake discs. The paragraph explains the difference between fluid and air, highlighting that while both are liquids, air is more elastic and thus unsuitable for pressure transmission in hydraulic systems.

Keywords

💡Brake

A brake is a device used to slow down or stop a moving vehicle. In the context of the video, it is the primary focus as the script discusses the sudden failure of a vehicle's braking system. The script mentions 'rem' which is an Indonesian term for 'brake', and the issue of brakes suddenly failing is central to the video's theme.

💡Hydrolic Brakes

Hydrolic brakes, also known as hydraulic brakes, use fluid to transmit pressure from the brake pedal to the brake calipers. The video explains that these brakes utilize brake fluid to function, and a problem with this system can lead to a sudden loss of braking ability, which is a key point in the script.

💡Fluid

In the script, fluid refers to the brake fluid used in hydraulic brake systems. It is a crucial component because it is responsible for transferring the pressure from the brake pedal to the calipers. The video discusses how the fluid's properties, such as being liquid yet able to transmit pressure, are essential for the brakes to work properly.

💡Pressure

Pressure in the video script is related to the force exerted by the brake pedal that needs to be transferred to the brake calipers to activate the brakes. The hydraulic system's ability to transfer pressure is vital for effective braking, and any issue with this transfer can lead to the brakes failing.

💡Brake Caliper

A brake caliper is the component that clamps onto the brake disc or rotor when the brakes are applied. The script explains that the pressure from the brake pedal is transferred to the brake caliper via the hydraulic fluid, which then squeezes the brake pads against the disc to create friction and slow down the vehicle.

💡Air Bubbles

Air bubbles in the script refer to the presence of air within the hydraulic brake system, which can interfere with the fluid's ability to transmit pressure effectively. The video describes how air bubbles can enter the system and cause a reduction in braking efficiency, which is a significant issue being explored.

💡Elasticity

Elasticity in this context refers to the property of air to expand and contract under pressure. The script explains that air's elastic nature means that when pressure is applied, its volume decreases, which can prevent the hydraulic system from effectively transferring pressure for braking.

💡Reservoir

The reservoir in the script is the part of the hydraulic brake system that stores the brake fluid. It is mentioned as a crucial component because it supplies the fluid needed for the system to function. The video script describes how the reservoir is connected to the brake system and how air can enter the system if the fluid level is low.

💡Piston

A piston in the hydraulic brake system is the component that moves within the brake cylinder in response to the driver pressing the brake pedal. The script explains that the piston's movement is what pushes the brake fluid to the calipers, and any issue with the piston's movement can affect the brake's performance.

💡Brake Pad

Brake pads are the parts that come into contact with the brake disc or rotor to create friction when the brakes are applied. The script implies that the brake pads are pressed against the rotor by the caliper, and the force exerted by the piston is what drives this action, highlighting the importance of the hydraulic system's integrity.

💡Air in Brake System

The term 'air in brake system' refers to the unwanted presence of air within the hydraulic brake system, which can cause the brakes to fail. The video script describes this phenomenon as 'rem masuk angin' in Indonesian, which translates to 'brakes entering air', and explains how this can happen and the negative effects it has on the braking system.

salah satu ketakutan kita saat

mengendarai kendaraan adalah ketika

remnya tiba-tiba blong sebenarnya apa

sih yang bikin rem ini tiba-tiba blong

di video ini saya akan coba membedah apa

yang terjadi pada sistem rem ketika

blong ini biasa terjadi pada rem

hidrolik ya jadi rem hidrolik itu

memanfaatkan fluida atau minyak rem

untuk menyalurkan tekanan simpelnya

tekanan dari tuas rem akan ke kaliper

untuk menjepit piringan rem dan yang

bisa mentransfer tekanan ini adalah

material berbentuk

fluida karena fluida itu bersifat liid

atau bentuknya bisa menyesuaikan tempat

dan bersifat Solid ketika

ditekan ini berbeda dengan udara meski

udara juga bersifat liuid karena bisa

menyesuaikan tempatnya tapi udara lebih

elastis dalam artian ketika diberi

tekanan volume udara akan mengecil tentu

hal ini tidak dapat dijadikan material

untuk mentransfer

tekanan lalu apa yang terjadi ketika di

dalam sistem rem hidrolik kemasukan

udara peristiwa ini biasa disebut dengan

rem masuk angin ini adalah kondisi di

mana ada udara yang secara tidak

sengaja masuk ke sistem rem

hidraulik lalu mengapa itu bisa

terjadi ini adalah animasi sistem rem

HID pada motor di bagian handle rem

terdapat tabung

reservoir tabung ini berfungsi untuk

menyimpan cadangan minyak rem Jadi kita

kalau mau mengisi minyak rem motor

lewatnya tabung ini dan tabung ini juga

ada levelnya jadi seperti ini kita bisa

lihat Apakah minyak rem masih ada atau

sudah habis tanpa harus membuka

tabungnya di bagian bawah tabung ini

terhubung ke silinder

input ini adalah mekanisme untuk memberi

tekanan pada minyak rem jadi pada posisi

seperti ini minyak rem dari reservoir

bisa masuk ke sistem karena salurannya

terbuka namun ketika kita tarik handle

remnya itu akan menggerakkan piston di

dalam silinder sehingga piston menutup

saluran reservoir dan gerakan piston

akan menekan minyak

rem dalam posisi seperti ini tabung

terisi oleh minyak rem tapi volumenya

sedikit sementara di atas minyak rem

terdapat ruang kosong yang sebenarnya

tidak kosong melainkan terisi oleh

udara nah udara inilah yang sangat

berpotensi masuk ke dalam sistem rem

hidrolik motor itu kan pas dikendarai

enggak selalu posisinya rata terutama

pas belok kadang miring ke kanan kadang

ke kiri nah saat posisi motor itu miring

permukaan minyak rem jadi bergeser kalau

posisi miringan motor itu terlalu tajam

ditambah kondisi minyak rem yang kurang

itu akan mengekspos saluran reservoir

terhadap udara jadi ketika Saluran ini

tidak terendam minyak rem di situlah

udara bisa

masuk memang sih udara yang masuk ini

hanya berupa gelembung kecil tapi kalau

ini terjadi cukup sering

gelembung-gelembung tersebut jadi banyak

dan efeknya terasa juga Lalu bagaimana

efeknya seperti yang saya katakan

sebelumnya udara itu bersifat elastis

Jadi kalau diberi tekanan volumenya akan

mengecil itu tidak akan bisa dipakai

untuk menyalurkan tekanan hidrolik

karena dalam posisi masuk angin ketika

piston menendorong minyak rem harusnya

dorongan itu disalurkan ke kaliper

sehingga piston di dalam kaliber bisa

mendorong kampas rem Namun karena ada

gelembung udara tekanan tersebut justru

digunakan untuk membuat gelembung udara

mengecil sehingga tidak ada lagi sisa

tekanan untuk mendorong piston di dalam

per itah yangadi ketika

rem
