The brakes of a car not only have to withstand extremely intense use. The disc brake system and all its parts are also an important safety factor. Both sports brakes that work perfectly have to be essential. That is why they should be checked every time a car is being repaired. But when should brake discs and pads be changed? And how is it possible to know when they are used? both scratched discs, and perforated discs or scratched and perforated discs.
HOW LONG DOES THE USEFUL LIFE OF THE BRAKES LAST?
Unfortunately, the exact time of the life of some discs and brake pads cannot be determined. Several factors influence the life of the brakes, do they work correctly? Daily life is influenced depending on the driving style, the weight of the vehicle and the quality of the mechanism. Brake wear also depends on whether a vehicle is driven heavily on highways or more in urban traffic. One thing is clear: brake discs and brake pads are subject to wear over time, since they convert kinetic energy into thermal energy by friction.
It is very possible that careful drivers arrive about 100,000 kilometers, with more than one set of brake pads. Drivers who prefer to have a faster driving style have to change the brake pads much sooner. The intervals of 10,000 to 15,000 kilometers would not be unusual. The same rule also applies to brake discs: the more intensely they are used, as a result of frequent and abrupt braking, for example, before they must be replaced.
WHEN SHOULD CHANGE THE BRAKE PADS?
At the latest, the brake pads must be replaced when they wear down to a thickness of less than two millimeters. Most modern cars are equipped with wear indicators to warn drivers when they should be replaced. With electronic systems and brake lines, wear is indicated accordingly by a warning light on the dashboard. With the purely mechanical version, a metal pin inserted in the pad makes an unpleasant noise when the wear limit is reached as a result of the metal pin coming into contact with the metal of the brake disc.
WHEN SHOULD THE BRAKE DISCS BE CHANGED?
The crucial aspect with the brake discs is the so-called "minimum thickness". This is the minimum dimension that each brake disc must have and specified by the manufacturer. It is abbreviated to "MIN TH" and can be found in the rim or in the brake disc chamber. Two to three millimeters of wear are generally acceptable.
The natural wear of the brake disc is relatively easy to detect. When a disc is used, a burr can be felt on the edge, since the disc only wears out where the brake pad is applied. The more pronounced the burr, the worse the disc wear. Experts use special instruments to measure the thickness of brake discs.
