Different Vein Designs of Brake Rotors


If you are planning to upgrade the brake rotors of your car, you will need to research about brake rotor vein design before making the final choice. There are many high-end brake rotors available in the market that makes use of patented and highly tested designs, which are really effective at dispersing heat when the stock rotors are not so effective.

When performance brake rotors are made at the factory, they are made so as to increase the surface area and improve air exchange to some extent. So a well-designed performance brake rotor will be made to work efficiently as a heat exchanger. They evenly disperse the heat across the rotor in a very effective way.

On the other hand, a stock brake rotor will not be much focused on increasing heat exchange and the focus will be on cutting down the overall manufacturing cost. This makes stock rotors lack surface area when compared to the high-performance racing brakes. As the rotor plates are placed closely in the stock rotors, air circulation will be cut down drastically.

Below listed are the different types of brake rotor vein designs, which you can see in stock as well as performance braking systems.

Straight Vein

This is the most common type of vein design that you will find on vehicles. This is the type of brake rotor, which has the lowest level of cooling capacity. This is also the lightest type owing to the reduced quantity of material content.

Variable Vein

This style of brake rotor is similar to the straight vein design. However, there are variations in the vein pattern to offer very good airflow across the plates of the brake rotor. The air turbulence offered by the veins helps in dispersing the heat produced while applying brakes in an effective way.

Pillar Vein

This type of brake rotor vein design is similar to the variable vein rotor design. However, they will have a more predictable vein pattern, and generally, they will not be patented.

High-performance brake rotors that are exclusively designed for racing cars make use of a Curved Vein design, as they are very effective in cooling the rotor. The design also helps to improve the reliability and strength of the rotors. In this design, the brake rotor surface area is the highest and the rotor act as a heat sink. The curved vein design makes the air to be semi pressurized before leaving the surface of the brake rotor.
