When brake disc replacement becomes necessary


Do you drive your car to work every day or travel frequently? Remember to check its condition frequently. Change the oil, take care of the condition of the tires, be sure to check the lights. The condition of the brakes is also very important, as they are mainly responsible for safety while driving.

Properly operating brakes ensure safety while driving. It is worth knowing how to take care of them, how damage to the disc and brakes is felt while driving a car, and how to replace them and extend their service life. If you do not want to do it yourself, contact the Kuta Autoserwis car workshop from Poznań . Experts will provide you with the necessary information and will also replace brake pads and discs for you. For more at Pomoc Drogowa Dąbrowa Górnicza 24H

 

Types of brake discs

As the driver presses the brake pedal, the kinetic energy changes to thermal energy, which increases the temperature of the brake disc. Each disc has a specific heat capacity, and when it is exceeded, the braking performance drops drastically. Increasingly, companies producing brake discs use advanced technologies for their production.

Monolithic shield - used in the most popular cars. They are more efficient than brake drums, but they heat up quickly and reduce braking power.

Ventilated disc - made of two elements, between which there are ventilation holes and dissipate the heat accumulating during the operation of the brakes. They heat up longer while maintaining a high level of braking.

ceramic disc - it is the most technologically advanced disc, which is made of ceramic elements covered with carbon fiber. It is mainly used in motor sports because it does not overheat.

Drilled and rubbed discs - are used in sports cars. Effectively dissipate heat through the grooves on the cutting surface.

What affects brake disc damage?

There are many reasons for deformation and damage to brake discs. The first problems may arise during their design for a specific car and the production itself. One-piece brake discs weigh approximately 8 kg and can be damaged during improper transport, storage and delivery to the customer.

The most common causes of damage and deformation of brake discs result from:

  • incorrect assembly;
  • improper service of brake systems;
  • improper tightening of the bolts of brake discs and wheels;
  • no information for the customer on the method of lapping new brake discs and pads.

There are also deformations and damage to the brake discs when the car is used incorrectly. Exceeding the safe, permissible operating temperature of brake discs, lack of adequate ventilation or cooling of the discs, sudden cooling of the hot disc by pouring cold water over them after a few hard braking applications may cause damage.

Incorrect selection of components for the brake disc has a huge impact on the friction coefficient, which affects the extension of the braking distance. A runout effect during braking indicates that the brake discs have been damaged. For more at Laweta Dąbrowa Górnicza
