The Wear Of Brake Pads Is Inconsistent. Do You Need To Replace Them At The Same Time?
In the process of driving, braking is an unavoidable action. The wear of brake pad needs regular inspection and replacement.
At present, most of the family cars are equipped with front wheel brake disc and rear wheel brake drum. Some advanced cars use brake discs. When the brake disc is braked at high speed, the heat dissipation effect is good and the braking is more efficient; The brake drum is airtight, and the heat dissipation is not as good as the disc brake of the brake disc, but the braking force is large. For example, big trucks and buses use drum brakes.
What is a brake disc and what is a brake drum?
brake disc
Literally, we can simply understand that the brake disc is a disc-shaped object. When the wheel turns, the brake disc turns. When it is necessary to brake, we can brake the wheel by rubbing the brake disc with the brake pad.
Brake drum
The shape of the brake drum is similar to that of a bell shaped iron casting. It also rotates with the tire. The structure is relatively complex. The cost of processing and manufacturing parts is relatively low, but it is difficult to adjust the brake clearance after wear and maintenance.
There is a reason for the use of front disc and rear drum in family cars. When braking, the car's center of gravity tilts forward, and the weight of braking is concentrated on the front wheels, so that the brake pads of the front wheels are seriously worn. Especially when braking on a curve, the weight of a car that used to lean forward is concentrated on the left or right wheels because of turning, which leads to inconsistent wear of the left and right brake pads. This is also a normal phenomenon.
Although the inconsistent wear of brake pads has a lot to do with the habit of car owners braking in curves, some people suggest that they slow down first when turning a corner, and then turn the steering wheel. I don't think it's necessary to change my driving habits in order to maintain the brake pads. Safe driving is the first priority.
When to replace the brake pads
Some people on the Internet say that the car will be replaced after driving 80000 km or four years, but this basis is not accurate and realistic. There is no way to determine the time to replace the brake pads through specific figures according to different car use needs and habits.
When there are the following phenomena in the process of driving, you must pay attention to check and replace the brake pads.
When braking, there is an abnormal sound, indicating that the brake pads have been worn out. It is also possible that the brake pads are mixed with debris, and the sound of debris rubbing against the brake disc.
The brake pads are not completely worn out, and the abnormal sound is not obvious. Some people may not feel the wear of the brake pads. At this time, we can judge whether there is brake fatigue and the braking effect is not as good as before.
Observe the thickness, generally new is the brake pad thickness is about 1cm, wear more than half can be replaced.
These details still need to be paid more attention to by car owners. It's good to check them regularly at ordinary times. The brake system is the most basic and important part. Needless to say, the repair shop will definitely check it.
How to maintain the brake pads
Try to avoid parking the vehicle in a dark and humid place for a long time, avoid blisters and prevent corrosion and aging of brake pads.
Don't brake hard. When driving normally, you can use point brake as much as possible on the premise of ensuring safety.
Brake pads are consumables. I think it's the same sentence. Don't pay too much attention to maintenance and neglect safety.
