How to understand that it’s time to change a brake disc
There are a number of factors that tell you that a brake disc needs to be replaced. The car owner should be alerted to symptoms such as:
Perceptible vibrations when the brake itself is depressed,
A rhythmic juddering of the pedal during braking,
The appearance of a metal squeak when turning the wheel.
However, the problems listed above may not occur only with disc wear, so it is better to apply to the service station to undergo diagnostics.
If the owner of a car is sure that the brake is the problem, he can make an additional check. At least, with the help of this method it will be possible to assess the condition of front disks, without removing a wheel. To do this, you need while driving on a level road at low speed, lightly press the pedal and for a couple of seconds turn the steering wheel alternately in both directions. If the rudder wobbles, it means the brake disks are quite worn, which is not surprising, as the front elements have the highest load.
But it will be difficult to check the state of rear disks independently due to the peculiarity of their construction. In this case, it is still better to contact a specialist.
