Pad cleaning and regeneration
The holes produce a scraping effect that cleans the surface of the pad from hazardous material deposits, thus preventing that even the slightest amount of ferrous material – that come from the brake rotor wear- can sediment on the friction material of the brake pad.
Wet brake performance
The holes serve to prevent water film that may form on the braking surface. Even when driving on slick roads the brake system responds effectively already at the first braking.
Brake system cooling
The presence of the holes leads to greater air circulation, resulting in improved heat dissipation capability and its increased performance.
