The wider slot actually draws cool air across the pad surface keeping pads and rotors cooler. They also expel dust, dirt and hot gases better than fine slots which eventually fill with rust and scale and become ineffective in our opinion. The blind drilled holes break down surface gases when braking from speed but do not weaken the rotor cross section as can happen with through drilling, thereby lessening the chance of rotors cracking over time and heavy use.
When you apply the brakes in your car it doesn’t just come to a stop on its own. Instead it relies on valuable parts known as brake discs that work alongside the brake pads to slow the car down or to bring the vehicle to a stop as safely as possible. Over period of time the brake discs will start to wear, affecting the overall performance of the braking system which can make driving particularly dangerous. In wet, wintery conditions especially it takes longer to stop in the first place, so its vital that the brake disc on all four wheels is checked regularly for signs of wear or damage.
