The normal work of the automobile brake system is the guarantee and premise of the safe driving of the automobile. In the impression of everyone, the three big parts may be the most important. However, in the event of a fault, the three big parts may only be costly to repair and brake. The system is often life-threatening, so the inspection of the braking system is particularly important. Many people do not understand the braking system, drum brake let alone check and maintain it regularly. Failure to regularly inspect and maintain the car's braking system will directly threaten the life and property safety of the driver when the braking system fails. So today Xiao Bian told everyone about the common brake system inspection which steps?

How to check the most important braking system and learn how to avoid safety hazards in time

1, brake fluid inspection

The fluid level of the brake fluid should be maintained between the upper and lower scales of the tank. If the brake cylinder is not scaled, the position of the fluid level should be 6 mm from the top of the cylinder. If you find that the amount of brake fluid is too low, immediately check for leaks, and add the same brand of brake fluid in a timely manner. You must not add other types of brake fluid or alternatives such as alcohol. If the brake fluid is dirty, it needs to be released and flushed and replaced with new brake fluid.

2, brake check

Generally, the new brake pad has a thickness of about 1.5 cm, and wear and thinning will continue during use. When the thickness of the brake pad is only about 1/3 (about 0.5 cm), it is necessary to constantly check the thickness of the brake pad. When the brake pad thickness is close to the special mark on the brake pad (about 0.2cm), it is necessary to prepare for brake pads, but now some models in the brake pad thickness is too thin, the position of the hand brake on the dashboard will be prompted, More convenient for the owner's inspection. Sometimes when you hear the sound of "iron and iron" rubbing on the brakes, the brake pads must be replaced immediately. If the brake pads are still sounding, you need to consider whether the brake disc has been damaged.

3, brake pedal inspection

When the brake pedal is depressed, there is usually a free stroke of about 6-20 mm. Under the free stroke, when the brake pedal is continued to be pressed, the pedal will have obvious resistance until it stops. If you find that when you step on the brake pedal, you need to step deeply to achieve the braking effect. The brake effect in the first half of the stroke is significantly lower than before. You can consider whether the brake pads are thin. If the first foot requires a deep tread and the second foot returns to normal, and the pedal is strongly elastic when the pedal is pressed strongly, air may be present in the brake circuit and it should be promptly discharged from the brake line. air. For a drum brake, if the distance between the brake pedal and the floor of the cab is too small when the brake pedal is depressed to the end, the clearance Auto accessories of the brake shoe may be too large, and the clearance of the brake shoe should be adjusted.

In the braking system, the most important factor affecting the braking effect is the thickness of the brake pads and the status of the brake fluid. Finally, once again, the majority of vehicle owners are reminded to constantly check the status of the brake pads and brake fluid to avoid emergency situations. Under the phenomenon of brake failure, causing unnecessary losses
