Should brake discs be skimmed?
All brake discs can be skimmed at least once. The only time your brake discs should be replaced is when they reach minimum thickness. Leading manufacturers have approved the Pro-Cut process of brake disc skimming.
How hot do car disc brakes get?
During normal street use, brake rotors and pads normally won’t see temperatures climb past 200 degrees Celsius, or 392 degrees Fahrenheit. However, track days are a different story, with temperatures potentially reaching 1,000 degrees Fahrenheit as the brakes are called upon more often and more aggressively.
How long does it take to skim a brake disc?
The automatic surface machining of a disc is completed in around 4 minutes. The complete process takes less than 10 minutes per disc. All brake discs can be skimmed at least once. The only time your brake discs should be replaced is when they reach minimum thickness. Leading manufacturers have approved the Pro-Cut process of brake disc skimming.
Can a pro cut skim remove a brake disc?
The Pro Cut skim removes only 4-6 thousandths of an inch and does not cause the discs to go below thickness. There is good logic for this type of “Renovation” of your brake discs rather than replace the discs with new ones for the simple reason that a good USED disc is actually a better performing product than a new one.
How does temperature affect a disc brake system?
Temperature changes of the brake cause axial and radial deformation; and this change in shape, in turn, affects the contact between the pads and the disc. Thus, the system should be analyzed as a fully coupled thermomechanical system.
What causes brake discs to go below thickness?
This does show that the brake discs have been quite hot and could encourage you to have your discs Pro Cut skimmed which can be performed several times during the life of your brake discs or rotors. The Pro Cut skim removes only 4-6 thousandths of an inch and does not cause the discs to go below thickness.

What should the temperature of the brake discs be?
For standard road cars, you should expect your brake discs to reach around 130°C. The brake discs on track cars can reach around 500°C, but these vehicles are built so they can cope with such an extreme temperature.

What causes a car’s brake discs to heat up?
On the left of he disc you can see the callipers (red) that have the pots and brake discs. The clamping of the discs causes friction and this is what slows you down. The friction causes heat and that has to be dissipated. The discs heat up (you might see brake discs glowing if you want night-time racing such as rally stages), as do the pads.
