How to determine the wear of the brake pads. Three control vectors

Unfortunately, or perhaps fortunately, no other method of braking a car wheel has been invented as yet, except by means of friction. An important part of this system are brake pads – friction pads that press against the brake disc or drum and stop the wheels turning. If you failed to brake and got into an accident, then use the service scrap my car pickering.


Replacement of brake pads is a necessary regular procedure, as their wear largely determines the quality of braking and directly affects the safety of driving.


For each car there are c

ertain recommendations on the frequency of changing the pads. It is believed that the pads should be replaced every 8-12 thousand kilometers. However, it is worth mentioning that you should not always be guided by the distance traveled. Every driver has his own style of driving, and if in case of calm traffic the brake pads may serve up to 20 thousand km, the fans of abrupt stops and aggressive drive will wipe their already for 5-6 thousand. In addition, much depends on the quality of the brake elements themselves, the ambient temperature changes and other factors.


So how can you determine the wear of the brake pads and the need for their replacement? There are several indicators that can hint at this.


  1. Under hard braking, you can feel a bouncing sensation.


Toward the end of their service life, the pads wear unevenly. This is also when chipping and cracking can occur. A worn out brake pad creates noise and a beating noise when braking. It is worth noting that this effect can also occur due to wear of the brake disc. In this case it needs to be reground or even replaced.


  1. the brake system does not behave adequately.


Too weak, or on the contrary, excessively sharp brakes can be an indication of wear of the pads. In the first case, you can notice that the brake pedal when you press it lower and braking is not as intense. And if the wheels are blocked sharply, it is possible that the friction lining has worn down completely and there is metal to metal friction.

In some cases, the pads are not noticeable when driving. It is worth looking under the wheel cover. If the plaque is uniformly dark (charcoal), the pad still has the liner. If you can see shiny metallic particles in the plaque, the liner is worn out and the pad is scratching the disc. If you see this picture – go to the service station immediately! This method of control is almost inapplicable for alloy wheels and ventilated brakes.


And yet, the best way to assess the need for replacement of brake pads is to have them checked by a specialist at the service station. During this procedure, the technician will inspect the brake discs and drums, assess the condition of the brake system hoses and fix minor imperfections. These are useful procedures, extending the trouble-free service life of the car and guaranteeing the driver’s safety.
