The brake is the brake. It is a mechanical part that stops or decelerates the moving parts in the machine.

　　Brakes play a vital role in vehicles and ordinary engineering. Therefore, knowing the characteristics of brakes can help improve work efficiency and enhance the feasibility of professional operations.

　　The characteristics of the brake are detailed as follows:

　　1. Good thermal stability. Because the scale of the brake conflict pad is not long, the area of ​​its working surface is only 12% to 6% of the area of ​​the brake disc, so the heat dissipation is better.

　　2. Good water stability. Due to the high unit pressure of the brake pad on the disc, it is easy to squeeze the water out, and it is also easy to shake off after being dipped in water under the effect of centrifugal force, plus the scrubbing effect of the pad on the disc. The first and second braking can recover to normal; and the drum brake needs more than ten braking to recover the normal braking performance.

　　3. The braking torque has nothing to do with the running and retreating of the car.

　　4. Under the condition of outputting the same size of braking torque, the quality and size of disc brakes are smaller than that of drum brakes. 5. Disc-type conflict linings are easier to replace after wear than drum-type conflict linings, the layout is simpler, and the maintenance is simple.

　　6. The gap between the brake disc and the conflicting pad is small (0.05~0.15mm), which shortens the operating time of the cylinder piston and increases the force transmission ratio of the brake drive organization.

　　7. The thermal expansion of the brake disc will not cause the brake pedal stroke to be lost like the thermal expansion of the brake drum, which also simplifies the description of the active gap adjustment device.

　　The selection of the brake is related to the normal operation of the machine. If the selection is unqualified, it will easily cause accidents.
