Brembo Sport Brake Discs VW Golf 5

Who should use Brembo Sport drilled or slotted discs?
Anyone looking for better braking performance with a simple change from your current brake discs to genuine Brembo Sport with either a drilled or slotted braking surface to maximize the interaction of the brake pad to the disc. Anyone who needs a better solution for their vehicles that are submitted to heavy braking. Anyone who has open spoke wheels and is looking for a finished “racing inspired” look to their brakes.

Should I use drilled or slotted Brembo Sport discs?
Brembo recommends the use of either the drilled or slotted design for normal road use.

What is the difference between drilled and slotted discs?
Drilled Brembo Sport Discs will operate at a slightly cooler temperature than the slotted version disc because of the added air surface created by the drill pattern. Slotted Brembo Sport Discs are recommended when using racing brake pad materials or the vehicle is submitted to extreme braking duties such as towing or hauling heavy loads. Both designs were engineered by Brembo to improve pad “bite”, improve wet weather performance, continuously refresh the brake pad and prevent gas from building up between the brake pad and disc.

Why are there so many holes in a cross-drilled disc?
The number of holes in a cross-drilled disc is part of the engineered system. Brembo has done extensive testing with regards to the number of holes, their size, their location and their chamfering. This attention to detail is what truly sets Brembo apart in the world of braking. The same attention to detail that is delivered to the Ferrari Formula One effort is a component of the high performance program.

Which direction should the discs rotate?
It is a popular misconception that drillings in a disc determine the direction of rotation. In truth, for an internally vented drilled disc, the geometry of the vanes dictates the direction of rotation. There are three vane types in use:
- Pillar vane (comprised of many small posts)
- Straight
- Curved vane
The first two vane types are non-directional, and can be used on either side of the vehicle. The curved vane disc, however, is directional. A curved vane disc must be installed with the vanes running back from the inside to the outside diameters in the direction of rotation. Orienting the disc in the manner creates a centrifugal pump. The rotation of the disc causes air to be pumped from the center of the disc, through the vanes, and out through the outside diameter of the disc. This greatly enhances the disc’s ability to dissipate heat. Additionally, all of Brembo’s slotted discs are directional, regardless of the vane geometry. The discs should be installed such that the end of the slot nearest the outer edge of the disc contacts the pad first.
