How long can a brake disc last?
Did you find such a problem when you went to have your car serviced?It seems that many times when we do maintenance, we only change some "oil and water", but few hardware are replaced?But some car users will find such a problem. The replacement of brake discs is always not in accordance with the maintenance manual. What's the matter?Go and have a look with the car boy!
In fact, the wear degree of the brake disc largely depends on the quality of the brake pad, and the rest depends on the material of the brake disc!
Why does the brake pad depend on the wear of the brake disc? First of all, the brake pad is the first to produce friction braking on the brake disc.A good pair of brake pads can not only produce strong braking force, but also cause as little wear to the brake disc as possible.
Generally speaking, how many kilometers do you need to change the brake disc?If the brake pad is unqualified, you need to check the brake disc about 5-8w km.If it is a qualified brake pad, just check it after 10W km.Generally speaking, there is no need to replace the brake disc within 20W km!
What degree of wear does the brake disc need to be replaced
In fact, this is also a more professional problem, but I still want to tell you how to distinguish.First of all, it depends on the smoothness of the brake disc. If there are no obvious scratches and grooves on the surface, it doesn't need to be replaced.
But it's ok if there are scratches. As long as it doesn't exceed the depth of 2-3mm, it can be used all the time. It just needs simple polishing.But if you exceed this depth, you must replace the brake disc.Otherwise, there will be the possibility of fracture, causing the danger of driving.
Summary
In fact, the brake disc is not easy to wear, but we still have to pay attention to its maintenance and use.How many kilometers do you usually replace your brake discs?Tell the car player in the comment area!
