Why should you change the brake pad of your car?
Brake pad are essential for your safety on the road. Its function is to generate the necessary friction to slow the movement of the brake disc, which is coupled to the wheel and stops it. For this reason, brake pad in good condition can make the difference between a braking in time and an accident.
Most cars have two brake pad per disc, which means that there is a set of four brake pad on the front axle and another set on the rear axle. These brake pad consist of a metal bracket and a lining, which is worn away with each braking, which means that its life depends largely on the number of times you brake and the intensity. Use engine braking is a strategy to protect them , but sooner or later you will have to replace the brake pad front and rear car brake.
When to change the brake pads?
Over time and use, the contact surface of the brake pads wear out, which means that the braking efficiency is reduced and the car will travel more meters before stopping. Fortunately, most cars now have a wear indicator on the dashboard, which tells you when the pads are about to reach the end of their life.
However, there are other signs that the time has come to change the brake pads, such as when you notice that you have to tread increasingly brake pedal to achieve the same braking effectiveness. In fact, the brake fluid is one of the first indicators that the pills have little time to live. When the pads are worn out, the piston of the brake caliper has to move further to compensate for the loss of material.
What is the minimum thickness of the brake pads?
As a rule, it is recommended to check the condition of the brake pads every 25,000 kilometers, although it is important to note that their wear will depend largely on your driving style. You should also consider that the front pads wear out more than the rear ones as they practically work twice as hard.
However, the best way to check if need to change the rear brake pads or front is to measure its thickness. In some cases, you only have to remove the wheel, but in other models you will have to dismantle the brake pads themselves.
Some brake pads have their own indicator of minimum thickness, which allows to evaluate their wear simply by taking a look. In other cases you will have to measure it , considering that when the material thickness is less than 2 mm at some point, there will be time to change the brake pads.
How much does it cost to change the brake pads?
Changing the rear or front brake pads is not expensive as it is an intervention that usually does not exceed 30 minutes, although the price varies depending on the vehicle model and the type of pill. However, you must consider that when you decide to change the brake pad, you have to replace all the same axis. You should change the rear and front brake pad of your vehicle at once. In addition, also make sure to thoroughly clean all parts, lubricate the pins and properly adjust the clamp.
