In this video we will see about different types of brakes.
In previous video I have already said our bikes have 3 brakes.
Front, Rear and Engine brake.
In this video we gonna see about different types of brakes.
In my left, 3 brakes are there. in this video, I'm going to discuss about that in detail.
In my left, two disc plate are there. in this some difference are there. I I'll explain what difference.
In my left this disc plate have holes on it. Why do we have holes in disc brake? I'll explain in this video.
Did you think why they put holes in the disc
I'm also have same question. I did search and I got it. I will share the same. Definitely it will useful for you.
Have you see some bikes have disc only in front not in rear wheel. You know why?
There are some reason to have disc in front and not in the rear. I will explain in detail in this video.
In this video, first we are going to see about different types of brakes
First we see about DRUM BRAKE
If you see Hero Splendor Plus both the wheels are having drum brake.
This is Drum brake
In this video, I'll see how drum brake works?
In drum brake the main parts are brake shoe and piston.
When braking brake fluid forces the piston to push the brake shoes outwards against the spinning drum.
The friction causes the vehicle to come to a stop.
If you see Bajaj Pulsar 220 both the wheels are having disc brake.
This is Disc brake
When the brakes are applied, Brake fluid forces the piston to push the brake pads against the disc.
The friction causes the vehicle to come to a stop.
Now we see about ABS
In KTM Duke 390 both the wheels are having disc brake but the difference is (ABS) sensor added to the disc.
Now, we see How ABS works?
Riding on non ABS bike. applying sudden brake the wheel gets lock up.
ABS uses speed sensor on the wheels to measure the wheel speed and avoid wheel locking.
ABS adjust the braking pressure to prevent the wheel from locking and motorcycle will be in our control.
Two types of Disc in Motorcycle
Petal disc and normal round shape disc
This is Normal Round shape disc which has small holes on it.
Petal type disc is the one which doesn't have round shape but has petal shape on edges.
The petal disc increase the total surface area of the disc
The petal disc has better heat dissipation quality compare to the round disc.
Petal disc mostly you can see in super bikes
Few normal bikes have petal disk. example Apache also having petal disc.
Why do we have holes in disc brake?
The disc which have holes drilled in them are called drilled rotor.
When brake pads grabs the rotor it's creates friction, which creates heat.
If that heat can't escape it leads to brake fade, which reduce the brakes stopping power.
Holes in the disc which allow air to flow inside so the heat reduce and brake pads will not fade.
Have you see some bikes have disc only in front not in rear wheel. You know why?
Disk brakes are more effective than drum brakes.
Braking the weight transferred in the forward direction. We need powerful braking at the front so disc are used.
Now you might ask why not use disc at rear?
Adding disc at both front and rear the only reason its cost more.
bikes have both disc brakes, but if you note front disc will be larger and rear disc will be smaller. You know why?
The best example, recently Bajaj release the Pulsar NS 200 bike with single channel ABS.
The front disk are larger than the normal version
The size of normal version pulsar NS 200 is 280mm.
ABS version of pulsar NS 200 disc size has been increased up to 300mm
The main reason to increase the disk size in the front because during braking the whole weight of the bike comes toward the front.
We need powerful braking at the front so that's why size of front wheel disc always larger and also its cost more.
