Rem Blong, Ternyata Ini Biang Keroknya
Summary
TLDRThis 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.
Takeaways
- 😨 Fear of Brake Failure: The script discusses the fear of brake failure when driving, specifically the sudden loss of brake function.
- 🔍 Investigating Brake Systems: The video aims to explore what happens in the braking system that causes the brakes to fail.
- 💧 Hydraulic Brakes: The script focuses on hydraulic brakes, which use brake fluid to transmit pressure from the brake lever to the caliper.
- 🔑 Fluid Properties: Brake fluid is a liquid that can conform to the shape of its container and becomes solid when compressed, unlike air which is elastic and reduces in volume under pressure.
- 🚫 Air in Hydraulic Systems: The presence of air in the hydraulic brake system, known as 'brake wind', can disrupt the hydraulic pressure transfer.
- 👀 Reservoir Function: The reservoir in the brake system stores brake fluid and has a level indicator to show fluid levels without opening the reservoir.
- 🔄 Fluid Movement: When the motorcycle is not level, especially during turns, the oil surface shifts, potentially exposing the reservoir to air and allowing air bubbles to enter.
- 💨 Air Bubbles: Small air bubbles can enter the system, and if this happens frequently, they can accumulate and affect the brake performance.
- 📉 Pressure Reduction: The elastic nature of air causes it to compress under pressure, reducing its volume and preventing it from transferring hydraulic pressure effectively.
- 🛑 Brake Inefficiency: When air bubbles are present, the pressure intended to push the brake fluid to the caliper is instead used to compress the air, leading to ineffective braking.
- 🛠️ Maintenance Tips: The script implies the importance of regular maintenance and checking of the brake fluid level to prevent air from entering the hydraulic system.
Q & A
What is the main concern addressed in the video script?
-The main concern addressed in the video script is the sudden failure of a vehicle's braking system, specifically when the brakes become soft due to air entering the hydraulic brake system.
What type of brake system is discussed in the script?
-The script discusses the hydraulic brake system, which uses fluid or brake fluid to transfer pressure from the brake pedal to the brake calipers.
How does the hydraulic brake system work in general?
-In a hydraulic brake system, the pressure from the brake pedal is transferred to the brake calipers through fluid, causing the calipers to squeeze the brake discs and slow down the vehicle.
What is the role of the brake fluid in the hydraulic brake system?
-The brake fluid serves as a medium to transfer pressure from the brake pedal to the brake calipers, ensuring the effective operation of the brakes.
Why is air considered a problem in the hydraulic brake system?
-Air is considered a problem because it is elastic and compressible, which can reduce the effectiveness of the hydraulic pressure needed to operate the brakes properly.
What is the term used to describe the condition when air enters the hydraulic brake system?
-The condition when air enters the hydraulic brake system is commonly referred to as 'brake air intrusion' or 'air in the brakes'.
How can air enter the hydraulic brake system?
-Air can enter the hydraulic brake system when the reservoir's air vent is exposed to the atmosphere due to the motorcycle's inclined position and insufficient brake fluid level.
What is the function of the reservoir in the hydraulic brake system?
-The reservoir in the hydraulic brake system serves to store the brake fluid and also has a level indicator to show the remaining amount of brake fluid without needing to open the reservoir.
What happens when air bubbles accumulate in the hydraulic brake system?
-When air bubbles accumulate, they reduce the hydraulic pressure's effectiveness, as the pressure is used to compress the air bubbles instead of being transferred to the brake calipers.
What is the effect of air bubbles on the braking performance?
-The presence of air bubbles can cause the brakes to feel soft and reduce their effectiveness, as the hydraulic pressure is compromised by the compressible air.
How can one check the brake fluid level in the reservoir?
-One can check the brake fluid level in the reservoir through a level indicator, which shows whether the brake fluid is sufficient or needs to be refilled.
Outlines
😨 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.

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
