Some Common Questions about Brake Pads

I believe that when replacing the brake pads, many car owners may find that the brake pads of the front wheel are larger than those of the rear wheel, whether driving forward or behind. In general, the brake wear of the front wheel will be faster than that of the rear wheel. So why?

 

 

Why is the front brake pad more worn than the 2010 f150 rear brakes?

 

Although the use frequency of the front and 2010 f150 rear brakes of the same vehicle is the same, the braking force of the front and 2010 f150 rear brakes on the wheels is different. When the vehicle brakes, the braking effect of the front wheel is much larger than that of the rear wheel. At this time, the front wheel needs more braking force. Therefore, equipping the front wheel with large-size brake pads is to ensure that the front wheel can have stable and effective braking performance when it bears more than half of the body weight.

 

At present, most models on the market adopt the front-drive layout. Generally, the front to rear weight ratio of this kind of model is 60:40; For the front and rear drive models, due to the addition of a set of the driving device on the rear axle, the front to rear weight ratio is only close to 50:50, but the front is still heavier than the rear.

 

In the process of vehicle braking, the wheels decelerate first, and the body will still have forward impulse under the action of inertia. At this time, the weight of the body will gather at the front wheels, but the pressure of the rear wheels will be reduced. In addition, the weight of the front of the car is large and the pressure of the front wheel is large, so the wear of the brake pads is relatively faster than that of the rear wheel.

 

Do you have to change the brake pads when changing the brake disc?

 

When replacing the brake pad, it is not necessary to replace the brake disc together. The replacement of the brake disc depends on the thickness and wear degree of the brake disc.

 

Most brake disc products have to wear indicators, that is, three small pits will be distributed on the disc. Measure the depth of the small hole with a vernier caliper, which is 1.5mm. In other words, when the total wear depth of both sides of the brake disc reaches 3mm, the brake disc needs to be replaced in time.

 

However, not all brake discs have wear indicators. You can also touch the outer edge of the disc by hand to judge the approximate depth. Generally speaking, if the total wear depth of both sides of the brake disc reaches 3mm, the brake disc should be replaced in time.

 

Is it normal for the brake pad to drop black powder?

 

The black powder produced by the brake indicates that the material of the brake pad is loose. The loose material indicates that the hardness of the pad is not high, which is often referred to as the film, but the film does not damage the brake disc, the premise is that the brake does not slip. If the black powder produced makes your brake slip, it is still very dangerous. If the brake is stable and noiseless, your powdered brake pad is of high quality.
