1. Cable-pull disc brakes, because the braking power is transmitted by the brake cable, it is inevitable that there will be the same weakness as the'V' brake: due to various factors such as the length and elasticity of the cable itself, and the friction of the shell, it will be lost. The braking force is reduced, resulting in insufficient braking. The above shortcomings can be solved by replacing the brake cable and maintaining the lubricity of the brake cable in the in-line tube.
2. Hydraulic disc brakes, the transmission material used in the brake system is oily objects, (usually DOT standard oil and mineral oil are commonly used. Among them, DOT-3 or DOT-4 is dedicated for automobile and motorcycle disc brakes. The composition of brake fluid is to overcome the characteristics of thermal expansion and contraction, but the substance is toxic and corrosive. It can melt the paint, and the advantage is that it absorbs water. The composition of mineral oil is very pure, and although it is non-toxic, it will not absorb it. Water does not wash off the paint. The advantage is that the braking force will not be reduced after a long time of use or encountering high temperatures.) Because the sealing property is the first thing to ensure when using oily objects for transmission, hydraulic discs The brake will lose the least power during transmission. At the same time, compared with the line pipe, the friction generated by the transmission of oily objects in the oil pipe is smaller than that of the transmission in the line pipe of the brake line, thereby more effectively reducing the loss of kinetic energy and enhancing the braking force. Compared with the performance of the two, the biggest difference is the difference in the transmission material and the difference in the braking effect. Cable-pull disc brakes have reduced braking performance due to the loss of strength caused by various factors. Hydraulic disc brakes have increased braking performance due to the smallest loss of power in the transmission. At the same time, the reduction of friction also provides for braking. Good hand feeling (a great braking effect can be achieved with a very relaxed force).
Performance comparison of V brakes and disc brakes
1. The advantages and disadvantages of the ‘V’ brake:
A. Simple structure, convenient maintenance, light weight
B. It is easy to lose the braking force generated by the fingers, especially in the situation of bad external environment (such as: rain)
C. The braking time should not be too long, it is only suitable for low-intensity use.
Actual application effect:
From the current point of view, V brakes are still relatively popular, but V brakes are best used only for low-intensity riding. Such as urban leisure riding, or road races. Such a one can ensure that you have enough brakes, but also can reduce the weight of the car itself, improve the riding pleasure.
2. The advantages and disadvantages of disc brakes:
A. The weight is inevitably heavier, and the structure is complex and difficult to maintain
B. Fear of oil stains and collisions with discs
C. High strength can better adapt to harsh environments
Actual application effect:
After installing the disc brake, it will inevitably be heavier than the V brake. But while sacrificing weight, you get enough brake protection. Disc brakes have almost no environmental requirements, and the only thing that needs attention is the care of the disc. Never let your discs get oily, and at the same time make sure that the shape of your discs cannot be deformed.
