00:00:00,00 --> 00:00:06,000
Let's talk about bicycle brake pads and different 
pad materials

2
00:00:11,500 --> 00:00:15,500
When bying new brake pads you may be in trouble 
with finding-

3
00:00:15,700 --> 00:00:20,900
-the right model, and also selecting the 
right friction material

4
00:00:21,000 --> 00:00:23,500
Today we are talking about these different 
materials-

5
00:00:23,600 --> 00:00:25,900
and let's concentrate on those two main categories:-

6
00:00:26,000 --> 00:00:30,800
-so called organic (resin) and sintered (metal) 
pads

7
00:00:30,900 --> 00:00:35,700
Now we focus on the friction material, the 
back plate is always metallic

8
00:00:36,800 --> 00:00:39,900
Terms organic/sintered pads refer to the 
friction material

9
00:00:40,000 --> 00:00:43,000
When talking about history-

10
00:00:43,200 --> 00:00:47,700
-bicycle brake pads were originally made 
from the same-

11
00:00:47,900 --> 00:00:50,800
-material as car and motorcycle brake pads-

12
00:00:50,900 --> 00:00:53,900
-and they are these  so called metallic pads

13
00:00:54,000 --> 00:00:57,100
Metal pad friction material is not actually 
metal, it contains some-

14
00:00:57,200 --> 00:01:01,700
-metallic particles and is made by some sintering 
process-

15
00:01:01,800 --> 00:01:05,300
-which leads to the other term: sintered 
pads

16
00:01:07,000 --> 00:01:11,400
SRAM calls them as sintered pads and Shimano 
as metal pads while-

17
00:01:11,500 --> 00:01:14,600
-naming within other brands varies a lot

18
00:01:14,700 --> 00:01:19,800
With this background it's very clear that 
metal pads are very durable-

19
00:01:19,900 --> 00:01:23,000
-they can stand very high temperatures

20
00:01:23,100 --> 00:01:27,000
Once we used an LPG torch for burning brake 
fluid residue away-

21
00:01:27,100 --> 00:01:31,100
-from an American car brake shoes without 
any harm to shoe material

22
00:01:31,200 --> 00:01:36,000
Metal pads have very high maximal braking 
power-

23
00:01:37,100 --> 00:01:42,200
-cars with even oldschool drum brakes will 
stop easily

24
00:01:44,000 --> 00:01:47,500
Very hard friction material has its own disadvantages

25
00:01:47,600 --> 00:01:52,400
New metal pads will take some time before 
they seat correctly-

26
00:01:52,500 --> 00:01:58,000
-to the brake disc and start to perform optimally-

27
00:01:58,600 --> 00:02:02,900
-running-in time is longer and-

28
00:02:03,000 --> 00:02:07,000
-they can even wear the brake disc during 
running-in

29
00:02:07,100 --> 00:02:11,000
Nowadays normal car service often includes 
also new brake discs-

30
00:02:11,100 --> 00:02:14,000
-just because of this reason

31
00:02:14,100 --> 00:02:18,900
One disadvantage, or feature, with metal 
pads-

32
00:02:19,000 --> 00:02:23,800
-is the on/off style braking feel

33
00:02:23,900 --> 00:02:28,700
To find the right braking power and braking 
style-

34
00:02:28,800 --> 00:02:33,000
-will need at least some adaptation

35
00:02:33,100 --> 00:02:37,100
Typical disadvantage is also the squeaking-

36
00:02:37,200 --> 00:02:41,200
-which is stronger with metal pads

37
00:02:41,300 --> 00:02:44,800
I have here pads of my own bicycles, they 
all belong-

38
00:02:44,900 --> 00:02:47,900
-to the resin pads category

39
00:02:48,000 --> 00:02:52,800
Shimano calls them resin pads, SRAM uses 
term organic pads-

40
00:02:52,900 --> 00:02:55,600
-while naming within other manufacturers 
varies also a lot

41
00:02:58,300 --> 00:03:02,100
Friction material contains mainly organic 
fibres-

42
00:03:02,200 --> 00:03:05,600
-casted together in some resin

43
00:03:07,000 --> 00:03:13,000
Resin pad advantages are mainly opposite 
of metal pad disadvantages

44
00:03:14,000 --> 00:03:18,000
The friction material is soft, running-in 
time is shorter-

45
00:03:18,100 --> 00:03:22,400
-maximal braking power can be achieved faster-

46
00:03:22,500 --> 00:03:25,900
-but the absolute maximal braking power is 
less-

47
00:03:26,000 --> 00:03:27,700
-compared to metal pads

48
00:03:27,800 --> 00:03:30,810
If you prefer maximal braking power-

49
00:03:30,500 --> 00:03:33,000
-then the resin pads is not your choice-

50
00:03:33,100 --> 00:03:36,900
-especially in wet conditions the braking 
performance will be lower-

51
00:03:37,000 --> 00:03:41,210
-as well as overheating will reduce the braking 
power-

52
00:03:41,300 --> 00:03:43,900
-other than metal pads

53
00:03:45,600 --> 00:03:50,100
In fact the metal pads need some warming 
before they will perform well-

54
00:03:50,200 --> 00:03:54,200
-and basically the warmer the better performance

55
00:03:54,300 --> 00:03:57,100
But, resin pads will hate heat...

56
00:03:57,200 --> 00:04:00,130
With resin pads you will find easier the 
braking feel-

57
00:04:00,900 --> 00:04:04,700
-braking will be more logical compared to 
brake handle pressure
