The heating of brake discs during braking is normal. The increase in temperature is due to friction between brake disc and pad. The average working temperature of the brake disc of the modern car is 200 to 300 degrees, but with aggressive driving with frequent brake applications, the temperature may reach between 500 and 700 degrees. The overheating of the brake discs may be dangerous, because the pad is not in contact with the disc, but literally "slip" by it, reducing the efficiency of braking. Causes of overheating of brake discs
Causes of overheating of brake discs
The most common reason for overheating is the driving style. The more aggressive you drive and the more often you have to slow down, the more likely the brake discs are to be overheated.
In addition, brake discs may be overheated due to malfunctions or features of the brake system of the vehicle: The brake disc or pad has been worn out above acceptable standard, the brake disc is substandard (requires replacement or pip), unquality brake pads, drum brake drum (as the brakes of this type are less efficient, the primary brake load is applied to the front brakes). How to prevent overheating of brake discs
- the brake disc or pad has been above the acceptable norm,
- the brake disc is subrosteny (requires a replacement or a protege),
- Failure of quality brake pads
- Drum rear brakes (as the brakes of this type are less effective, the primary brake load is applied to the front brakes).
How to prevent overheating of brake discs
The reason for the overheating of the brake disc is that it is easy to remove the rules that will prevent this.
- First, it is a moderate style of driving without abrupt braking.
- Second, this is timely service of brake system components, regular replacement of pads and discs.
- Third, the use of quality components.
Besides, we do not need to wash the car immediately after the stop (especially in summer). The brake discs need time to cool, so the sharp drop in temperature may result in deformation of the brake disc.
To determine overheating of brake discs
Only the specialist can fully diagnose the brake system (including brake discs), but you can perform visual inspection on your own. To determine the condition of the brake discs and the temperature to which they are heated, use the colour of the steel from which the disc is made:
- The yellow is 150-280 degrees,
- blue is 300-450 degrees
- Black is 450-500 degrees.
