What Is The Difference Between The Speed Of The Left And Right Brake Pads?

It is a common phenomenon that the brake pads are worn at different speeds. Under normal circumstances, the wear speed of the brake pads on the two front wheels of a car should be the same, and the wear speed of the two rear wheels should be the same. The front wheels of most vehicles wear faster than the rear wheels, and the front brake pads are changed about twice before the rear brake pads are changed. This is because the center of gravity of the vehicle moves forward during braking. Checking the wear of the brake pads sometimes shows that the wear on one side is extreme, and the other side is still very thick. What is going on? The Ford Brake Pad supplier will tell you below.

Most of the reasons are caused by poor return of the brake cylinder. When the brake is not stepped on, the gap between the brake pads and the brake disc is very small, and the two are next to each other so that they can respond quickly when the brakes are pressed. When the brake is stepped on, the piston of the brake cylinder is moved outward to apply force to the brake pads, and the two brake pads will clamp the brake disc, and the discs and the discs rub against each other to generate braking force. When the brake is released, because there is no braking force, the piston of the brake cylinder is moved back, and the brake pads quickly return to the initial state. However, if the piston of the brake cylinder on one side is poorly returned, even if the brake is released, the piston still does not go back or goes back slowly, and the brake pads will be subject to additional wear, and the brake pads on this side will wear faster. I once encountered the pistons of several sub-pumps in a stuck state, and the side wheels were always in the state of light braking.

In addition to the stuck piston, if the guide pin of the cylinder is poorly lubricated, it will also cause poor return. The sub-pump needs a slideway to move left and right. Sliding is a guide pin. It moves on the guide pin. If the rubber sleeve of the guide pin breaks and enters a large amount of dust and dirt, the friction resistance is greatly increased. Or the brake pads are not properly operated and the guide pins are bent. In both cases, the moving speed of the sub-pump will also be blocked, and the brake pads will wear quickly.

The above are the two most common reasons. Both ordinary brake pads and Ferrari Brake Pad may be caused by these two factors. The difference in speed here is very different. For example, one side is worn out, the other is There are still half or one third of the side. If the difference is not normal, the degree of wear of the brake pads on both sides of all cars will not be the same, and there will be differences. Because the brake pads are subjected to different forces when braking under different road conditions, such as braking while turning, the center of gravity of the car will shift to one side, and the braking forces of the wheels on the two sides will be different. Therefore, the wear of the brake pads cannot be the same It can only be said that it is roughly the same.

In addition, can you feel that the brake cylinder has a poor return? When you brake, you can feel it, and the brake will drift, because the difference between left and right braking force will be larger. If you are completely stuck in the brake state, you can feel the start and acceleration, and you will feel the car is particularly heavy, like pulling the handbrake. Some will also hear squeaking friction, and the wheels on the side will be abnormally hot. In short, the car will obviously feel abnormal when it is driven. At this time, it is necessary to check it in time. The braking deviation is still relatively dangerous. The driver cannot control the direction at all, especially when the speed is fast.

The above are the factors that Chevrolet Brake Pad Manufacturer shared the different levels of wear and tear of the car brake pads, I hope to help everyone.
