What is the cause of grinding brake pads？
Many friends asked, new brake pads to polish, I think it is best to polish the edges better, because if the brake pads are installed directly on, there may be two problems, one is that the edge of the brake pads will be in contact with the inner and outer ring steps of the brake disc, issuing a scuffing sound, two, especially the purchase of sub-brand brake pads more attention to this problem, once encountered in the auto parts city to buy unknown brake pads, installed on the brake can not brake, take off a look, the brake pads are too wide, both sides of the pads directly pressed on the brake pad steps, no contact in the middle, this situation, of course, can not brake the car.
The picture below shows a polished brake pad, beveled inside and out.
The above is the reason why you need to grind the brake pads as introduced by me.
So when installing brake pads, according to the wear of the brake disc, the height of the step to polish the brake pads.
Our auto mechanic found the disc grinding too deep when replacing the brake pads, and took the brake pads to the store door with an angle grinder to polish them, the owner was surprised, and afterwards the owner said he thought we had deliberately ground them thin to shorten the replacement mileage, which was not the case.
What is the cause of brake pad wear?
Brake pads are worn differently on both sides of the brake pads, which should be dealt with as soon as possible or it will be harmful to driving safety.
The brake pads are worn differently because the brake fluid has not been replaced for a long time, resulting in too many impurities affecting the fluidity of the brake fluid, making the piston in the brake sub-pump not return well, and over time the sub-pump does not return, and there is always pressure on the brake pads regardless of whether or not the brake pads are working, which causes the phenomenon of bias grinding with brakes.
Long time driving bad road conditions cause the brake system brake pump excessive aging wear and tear and thus cause the brake does not return to the phenomenon, causing the brake bias grinding.
Older cars also have a brake distributor pump caliper does not return, that is, can not move laterally phenomenon, which is also the cause of uneven brake pad bias wear, the way to deal with the caliper shaft grinding processing can be or replace the new brake distributor pump assembly.
These are the causes of uneven brake wear, and also the cause of the car sinking when starting with the brake.
These are the reasons why the car has been around for a long time, and there are also man-made reasons such as not letting go of the brake, and replacing the brake pads with bad quality pads will also cause the partial wear phenomenon.

Brake Pad Tips
Brake pads are not the harder the better. Some businesses will advertise that their brake pads are wear-resistant and do not lose powder, but in fact this means that the brake pads are too hard, sacrificing friction and extending the life, putting the cart before the horse. A good brake pad is not wear-resistant as the first indicator, but can provide strong friction, so a moderately hard and soft brake pad is the best, brake pads falling off powder is a normal phenomenon, indicating that it is working, brake pads that do not fall off powder is fake.
