What is the Types of Car Brake Discs

In ancient times the vehicles mounted braking systems that consisted of a drum made of iron that inside were the brake shoes that were activated when the driver stepped on the brake, the shoes expanded and produced friction against the drum thus causing the braking.

But when the brake abused a lot, the lack of efficiency in braking was felt as they reached very high temperatures due to the friction of materials, so they would soon be replaced by the disc brakes normally in the front train and drums in the back.

Currently, many of the models already mount discs both in the front and rear train to improve braking efficiency, since the difference between using one system and another is more than noticeable the advantages of the discover the brake drum.

But what types of brake discs exist?

The types of discs that we can see today are very varied, although par excellence in current conventional models mounted ventilated disc in front and a solid disk behind enough for 100cv cars.

But in the market there is a lot of variation between models and engines which causes variations here, let’s analyze the brake discs:

– Solid disk: it is a solid piece of metal that, by the friction of pads, pressed by a brake caliper against the brake discs, can stop the vehicle. Many of these discs we will see in the front of powerful little cars ( Golf 3 Diesel, for example) or the rear of many current cars or with more than 100cv, are the difference, for example, the rear bridges of a 1,1Lde 60 or 1,4L 75cv saxophone with drum at 1, 6L or 1.6 16v with 90/100 or 120hp respectively with disc on the rear bridge.

– Ventilated discs: mounted on most vehicles, the difference with the massifs is that they have internal ventilation that allows faster heat dissipation and more optimal brake response, a great improvement.

– Ventilated and perforated discs: it has internal ventilation, and it differs because it has some grooves or perforations on the surface of the discs, allows a greater degree of efficiency in braking. We will find it in vehicles more powerful than the average, Mercedes AMG, and cars like that.

– Ceramic carbon discs: they had sports applications in F1 or sports racing for a long time, although Brembo in 2002 joined the 2002 Ferrari Enzo with them, followed by Lamborghini, Mercedes, Chevrolet, among others.

Currently, you can see many cars in the national Rails with this system; they are characterized by the red color that they generate when braking, they need to be heated before starting the race since they work in a temperature range.

Currently, in Spain, if you want to modify the braking power of a vehicle, you must make a reform in the technical file to be homologated.
