Are rotors with holes better?
The bite is better with these brake rotors because the drilled holes give the water a place to escape, thus drying off the braking system components when water is present. Less water means a better bite and improved brake rotor performance. Cons: Drilled brake rotors are fine for general use in street vehicles.
Do pitted rotors need to be replaced?
Brake rotors will rust. Usually it’s just surface rust that will wear off after a couple of miles of driving. If the rust is deep — to the point of pitting — it is certainly possible the rotors need to be replaced.
What’s the point of drilled and slotted rotors?
Drilled and slotted rotors are brake rotors with holes and slots in them. They’re designed to evacuate the moisture and brake dust generated during braking, facilitate the cooling of your brake disc, and increase your contact friction for superior brake performance.
Are slotted rotors worth the extra money?
Slotted rotors do not improve any heat transfer. However, the slots can improve brake output by removing gas and dust that is trapped between the pad and rotor. Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving.
Can you resurface pitted rotors?
Resurfacing Your Rotors Sometimes your rotors may need to be resurfaced because they have worn unevenly, warped from heat, or become damaged by worn brake pads or pitted from corrosion or rust. Resurfacing rotors removes some of their metal, until the surface is smooth and even again.
Is it worth getting drilled and slotted rotors?
Given the choice between drill holes and slots, the drill holes will give you better braking power over slots for normal city/highway driving. This is why high end BMW, Porsche, Corvette, and Mercedes rotors are drilled, not slotted. However, for track racing (high speed stops), slotted rotors are the better choice.
Are slotted rotors better than solid?
As a result, if you’re seeing a lot of track time, slotted brake rotors are better than drilled or solid ones. These benefits still translate over to the street. However, those slots mean your brake pads won’t last as long. Ultimately, upgrading your brake rotors depends on how you drive.
