The first step; Check the stroke of the brake handle, the stroke is too large, the braking effect is poor, and the brake handle cannot be stopped in an emergency, and the brake handle stroke needs to be adjusted. The brake handle should be reduced to a normal range.
The second step; Brake wire setting screws. Brake line setting screws are used to tighten the brake line and adjust the stroke of the brake handle. When adjusting the brake line fixing screw, it should be loosened a little, not all. If fully released may cause the brake line to detach.
The third step; Adjust the brake line fixing screw, loosen the No. 10 of the No. 10-12 wrench to adjust the brake line screw and pull the brake line on the line (the wrench should be turned counterclockwise to loosen), loosen one to three laps.
Step four; Pull the brake cable, release the adjusting brake cable screw, hold the brake cable tightly with the right hand and pull back a little hard.
Step five; To tighten the brake cable fixing screw, tighten and adjust the brake cable screw with No. 10 of No. 10-12 wrench (wrench should be turned clockwise to tighten), tighten it, do not tighten the screw.
Step six; To check whether the trip of the brake handle is qualified, the brake handle should be held with the left hand and the rear wheel of the electric vehicle should be turned with the right hand. Adjust the brake handle stroke within the normal range.
Step seven; Check the stroke of the brake handle, the stroke is too small, the braking effect is good but the electricity is wasted, and the brake handle stroke needs to be adjusted. The brake handle should be increased and adjusted to the normal range.
Step eight; Brake wire setting screws. Brake line setting screws are used to tighten the brake line and adjust the stroke of the brake handle. When adjusting the brake line fixing screw, it should be loosened a little, not all. If fully released may cause the brake line to detach.
Step nine; Adjust the brake line fixing screw, loosen the No. 10 of the No. 10-12 wrench to adjust the brake line screw and pull the brake line on the line (the wrench should be turned counterclockwise to loosen), loosen one to three laps.
Step 10; After tightening the brake line and releasing the adjusting brake line screws, gently hold the brake handle with your left hand to bring the brake line back
Step eleven; To tighten the brake cable fixing screw, tighten and adjust the brake cable screw with No. 10 of No. 10-12 wrench (wrench should be turned clockwise to tighten), tighten it, do not tighten the screw.
Step 12; To check whether the trip of the brake handle is qualified, the brake handle should be held with the left hand and the rear wheel of the electric vehicle should be turned with the right hand. Adjust the brake handle stroke within the normal range.

The brake device generates friction between the brake pad and the wheel drum or disc, and converts the kinetic energy of the car into heat energy in the process of friction. For a good car, a reliable brake device is essential. Manual brakes have been around for centuries. In the mid-to-late 19th century, various power brakes were invented, such as pneumatic brakes for steam and air, vacuum brakes, and hydraulic brakes, which were used on trains and other vehicles.
Early cars generally used belt brakes or shoe brakes, which were mounted on the rear wheels of the car and mechanically attached to a joystick or pedal. In 1904 Renouf patented the front wheel brakes. This brake was improved by Allen two years later and installed on the Argill in 1909. After Ford proposed a variety of interchangeable separate brake linings in 1900, a wide variety of brake linings were soon available that could be matched with steel or cast iron brake wheels. In 1902, Renault invented the standard brake wheel, which had two hinged brake shoes separated by a CAM. From 1919, Dewand et al. obtained a series of patents on hydraulically assisted servo brakes. In 1920, Bendix et al. used double servo brakes in automobile braking devices in order to brake more safely and smoothly. The characteristics of the 1906 Darak brake are the same as the modern brake principle, which is manufactured in various disc shapes. On later brake devices, in order to increase their sensitivity and reliability, new technologies such as electronic sensing were used. This will ensure that the brakes can stop the fast-moving car in a very short time.
Common brake device types:
First, drum brake: two semi-circular brake pads are installed inside the wheel hub, and the \"lever principle\" is used to push the brake pads so that the brake pads contact with the inner surface of the wheel drum and friction occurs.
Second, disc brake: brake calipers control two brake pads to clamp the brake disc on the wheel. When the brake pads clamp the disc, there is friction between them.
When the car is driving on a wet or icy low-friction road surface, if excessive braking occurs, the wheel will be locked by the brake device and lose the grip, resulting in the vehicle losing the ability to control the direction. In order to enable the vehicle to effectively control the direction of advance on this dangerous road surface, ABS \"anti-lock braking system\" was developed.
Increasingly powerful ABS \"anti-lock braking system\
Three, inflatable brake
Basic structure: The brake device is composed of three parts: a drive shaft, a fixed hollow shaft and a high elastic sealing rubber ring. The fixed hollow shaft sleeve is on the drive shaft, and there is a large gap between the two. In this gap, a high elastic sealing rubber ring is installed. The inner ring of the rubber ring is always rigidly connected with the drive shaft, and the outer ring is inlaid with a number of friction plates, leaving a certain gap with the inner diameter surface of the fixed hollow shaft.
Working principle: When the high elastic sealing rubber ring is not filled with high pressure air, there is a gap between the friction plate and the inner diameter surface of the fixed hollow shaft, at this time, the drive shaft can rotate freely. When the high elastic sealing rubber ring is filled with high pressure air, the rubber ring expands due to inflation, its outer diameter becomes larger, the gap between the original and the fixed hollow shaft disappears, and the friction plate becomes rigid contact with the fixed hollow shaft, at this time, the drive shaft is \"expanded\" by the rubber ring in the fixed hollow shaft and stops the transmission to achieve the brake function. When the pressure in the high elastic sealing rubber ring is released, its inner diameter becomes smaller, and the drive shaft can rotate freely.
