Just like your gas mileage varies depending on where and how you drive, the same way it varies with the brake pads or linings. The friction material of the break gets pushed against a metal disc or drum to stop your vehicle. They do not have so much life that it will last long so in this case you should have your car brake repair.
An auto brake repair depends on a lot of factors.
If you mostly drive in a crowded area
Your car brakes need proper maintenance as if they are not functioning well then it may danger your life. If you drive your car in the crowded place even if you have driven just 8,000 miles a year then also it requires maintenance. Whereas comparing to those who drive on high ways for 28,000 miles a year.
When you check the tires of car
Most of the vehicles must have their tires rotated at least every six months, and this is also a good time when you should inspect your breaks. An auto mechanic can check the width of the tires and also the condition of the brake hardware.
When you hear annoying screeching sound from brakes
Many of the cars have built-in damage sensors that scour against a brake disc when need replacement. Also, those who do not have can also focus on break sound if they hear some indifferent sound while pressing the break then also they should make it check by an auto mechanic.
