Many people are fascinated by racing and sports cars. One of the many advantages of such cars is their ability to quickly lose speed – by braking. This is of course due to the technology and materials made for the production of various braking systems. Differences between braking systems can be plain recognized by the different diameter of brake discs. However, the braking force is also influenced by many other factors, such as the type of brake calliper, the number of pistons installed in the calliper, also the material from which discs and pads are made, as well as the boiling point of the brake fluid.

Why are powerful racing brakes not fitted in streetcars?

Because they are optimized for use in normal driving conditions, the brakes on a race car are exposed to frequent, heavy braking. This causes much higher temperatures in the system. Unlike streetcars, where we don’t always brake with 100% strength, and the braking intervals are much longer than on the track. Also, street brakes must maintain similar efficiency when working in frost and 35 degrees heat, heated and unheated. In a racing car, the brakes reach their 100% efficiency only when they reach a given temperature. The whole system is also designed so that the discs are warmed up and at the same time cooled after sharp braking to the corner.

Why do my brakes get weaker with each lap on the track?

Because the result of braking is the friction of the brake pads against the disc – this increases the temperature of the friction elements and the brake fluid. At some point, the brake fluid reaches its boiling point, which causing air bubbles to develop in the fluid in the system. Unlike brake fluid, the air has a very high elasticity. This means that when we try to build up pressure in the braking system, the air molecules absorb some of the force generated.

Is it possible to improve the braking system in my car?

Of course. Depending on your needs, there are many ways to increase the effectiveness of your brakes. Starting from track brake pads, by changing the brake fluid with a higher degree of boiling, you can already get a set of brakes that will be satisfactory for daily use interspersed with track days. Changing the brake hose to a steel braided one provides greater resistance to pressure in the brake system and is more resistant to damage. If you are interested in something more professional, many manufacturers offer ready-made sets that also include larger brake discs and larger callipers. To ensure the possibility of correcting the braking force of the front and rear axles, we install special sets of pedals that have separate cylinders for the front and rear axles.
