Types of e bike brake pads
At present, there are two main types of mainstream e bike brake pads for two wheeler electric bike, namely drum brake and disc brake. However, in recent years, a new type of brake has emerged in the electric vehicle industry, that is, ceramic brakes.
Disc brakes are commonly known as hydraulic brakes or oil brakes or disk brakes;
Drum brakes are e bike brake pads with a traditional braking method of deceleration by friction between the wheel hubs. For more information, please click to check electric motorcycle hub motor vs mid drive.
Ceramic brake working principle for a move double brake, reasonable distribution of braking force, whether the left brake or right brake can be simultaneously on the front and rear of the two tires for braking.
The mainstream practice on the market is generally to use disc brakes on the front wheels and drum brakes on the rear wheels, the so-called “front discs and rear drums”. The rear wheels do not use disc brakes mainly for cost considerations, this configuration is being replaced by front and rear full disc brakes.
In general, disc brakes are better than drum brakes. The larger the diameter of the disc, the better, the more pistons in the caliper, the better, and the lighter the weight, the better.
Feature of disc brake and drum brake
Advantage：
Disc brakes generally do not have friction-assisted effect (not easy to hold), so the brake efficiency is less affected by the friction factor, and the efficiency is more stable.
Less reduction in effectiveness after immersion in water and return to normal after only one or two braking cycles.
Smaller size and mass for the same output braking torque.
The thermal expansion of the brake disk along the thickness direction is extremely small, and it will not cause the brake clearance to increase significantly like drum brakes and lead to excessive travel of the braking mechanism.
It is easier to realize the automatic adjustment of the gap, and other maintenance and repair operations are relatively simple.
Disc brake ventilation and heat dissipation is good, not like the drum brake as easy to heat accumulation so that the brake part of the heat exhaustion, braking force weakened.
Disadvantage：
The braking effect is slightly worse than the drum brake, so it is used in the hydraulic braking system when the required brake actuator line pressure is higher, generally use servo devices.
Also used for parking brake (which mainly exists in the car), need to add the parking brake transmission, more complex than the drum brake, and thus the application of the rear wheels is limited.
Higher cost than drum brakes.
Of course, with the improvement of living standards, ABS in the electric motorcycle manufacturers is gradually popularized, the drum brake is more and more no market. But because of its braking effect, I believe that in some professional fields will still have a place, will not disappear.
Feature of ceramic e bike brake pads
Ceramic e bike brake pads is a new type of brakes, often used in motorcycles and automobiles, including the products of top 10 electric motorcycle manufacturers in China. In recent years there are electric vehicle companies began to apply this type of brakes.
It works on the principle of double brakes in one motion, reasonably distributing the braking force, no matter the left brake or the right brake can brake the front and rear tires at the same time.
Advantages:
It can effectively avoid dumping and side sliding. In addition, thanks to the use of enhanced composite ceramics and the Rola force-saving structure, the braking power of the vehicle can be greatly improved and more resistant to wear.
Disadvantages:
Ceramic brakes cost the most and are significantly higher than disc and drum brakes.
Which type of e bike brake pad is the best？
Comprehensively, the overall performance of ceramic brakes is the best, while the disc brakes are relatively second, and the drum brakes are relatively the worst, so if you do not consider the price factor, users can consider ceramic brakes more often.
Therefore, if you do not consider the price factor, users can consider ceramic brakes more when choosing brakes. If you want to look at the price, then the choice of disc brakes is better, which can guarantee the performance, but also can take into account the price. So, for the e-bike drum brakes, disc brakes, ceramic brakes, which one will you choose?
E bike brake pads abnormal sound causes and solutions
Disc brake abnormal sound cause analysis
Disc brake is a common type of brake for electric bicycles, the brake disc is a metal disc, and the e bike brake pads are installed on the brake pliers. When you start pulling the brake handle, the brake pump pushes the brake oil, so that the pressure in the brake tubing increases, which pushes the e bike brake pads to contact the brake disc, generating friction and achieving braking. We can speculate that the disc brake abnormal sound, should be the following reasons:
1. E bike brake pads wear seriously or poor material
E bike brake pads (e bike disc brake pads) are the core component of disc brakes and will wear out over time with use. When e bike brake pads are badly worn, their thickness thins out, leading to excessive clearance with the disc brake disk. This can lead to frequent and noticeable rattling of the brakes during riding.
In addition, if the e bike brake pads are made of poor material, it may also lead to rattling when braking, the solution is to replace the e bike brake pads with new ones.
2. E bike brake pads and disc brake disc gap is too small
If the gap between the e bike brake pads and the disc brake disc is too small, friction will occur during braking, resulting in abnormal sound. The solution is to adjust the gap between the e bike brake pads and the brake disc.
3. There is something on the disc brake
Disc brake discs have dust or into foreign objects, can also lead to brake noise, which is very common, you need to pay more attention. There is no need to worry about the rattling, just take it off and clean it up.
When do you need to replace e bike brake pads
From the following three aspects to determine whether your e bike brake pads should be changed.
1.Thickness of e bike brake pads
When the thickness of the e bike brake pads becomes very thin, the braking function will fall sharply, affecting driving safety. The thickness of the e bike brake pads in the following figure is about 9mm, and the square is 7mm. When the e bike brake pads wear to < At 5mm, it’s almost time to replace it.
2. Abnormal brake sound
Brake time, try to listen to the brake when the sound, if you hear a similar iron grinding iron sharp sound, we must pay attention to the electric car used for a long time, the various parts and connections of the oil dry, easy to have a rattling sound. Rear shock absorber is also a place to send out the sound, solution: drop some oil, lubrication. If the inner core is seriously deformed, it needs to be replaced.
3. Brake response and spacing
When the e bike brake pads become thinner, the brake response of the electric bike will also become slower, and you need to press the brake deeper and heavier to reach the former braking result.
When you find that the first half of the braking result is obviously weakened by pressing the brake, the brake becomes softer, a little brake, you have to check whether the e bike brake pads need to be replaced.
Can e bike brake pads be repaired if they are broken?
General electric vehicles are “front disc back drum” configuration. But no matter what kind of brake, it is easy to wear, because its daily use frequency is very high. In the case of e bike brake pads, with the use of time, it will slowly thin, and after thinning, there will be a decline in braking performance, which is one of the main reasons for many electric vehicle brake failures.
At this point, there are only two options to solve the problem. First, is to tighten the e bike brake pads, so that it is closer to the tire, increase the friction, but this way is not reliable, because the e bike brake pads will become harder after wear, but will hurt the tire.
Second, it is to replace the new e bike brake pads, and this way is more reasonable. Therefore, many repair masters are choosing to replace rather than repair, and this is to extend the service life and better protect other accessories. And then we look at the maintenance cost, because the price of the brake itself is not high, but the maintenance takes longer than the replacement.
From the maintenance results, even if the brake can be repaired, it is likely to occur again in a short period of time after maintenance. From this point of view, replacement is also more reliable than maintenance. Of course, if only some screws are loose, or the brake line is loose and the brake is broken, the maintenance master will try his best to help the user solve it.
How to see e bike brake pads model
If the old e bike brake pad is complete, then you can directly measure the diameter with a soft ruler, tell the business or take a photo. However, if the e bike brake pads are broken, they cannot be measured and are not accurate, then you can put the tape measure into the wheel to roughly measure the inner diameter of the brake pan to know the size of the required e bike brake pads.
The most safe is to let the maintenance personnel view and measure, generally experienced maintenance personnel to see the size of e bike brake pads.
