Are smooth rotors good?
Smooth / Blank rotors have the most surface area and are highly effective as a heat-sink. They are least prone to cracking. Smooth rotors are recommended for most vehicles that are not used for extreme or repetitive braking.
Can you smooth 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.
What kind of brake pads cause more wear on rotors?
Semi-metallic brake pads usually contain a very high percentage of chopped steel fiber, so they typically cause more wear on the rotors than most ceramic or non-asbestos organic (NAO) brake pads.
What happens if you dont replace your brake rotors?
If you still decided against replacing your brake rotors the brake pads would keep wearing away the brake rotor bit by bit. Until one day the brake rotor would crack and break into pieces likely causing damage to surrounding parts and your wheels. At that point, you would no longer be able to use that brake at all.
How can I correct runout on my brake rotors?
Rotor runout also can be corrected using a conventional bench lathe, but it requires a multi-step process. First, you have to measure and mark the point of maximum runout with the rotor on the vehicle. Then, you have to mount the rotor on the lathe arbor and attempt to duplicate the same amount of runout on the lathe.
What should the surface finish of a brake rotor be?
The surface finish on the rotors also is important because it affects the friction characteristics of the brakes, pad seating, break-in, wear and noise. Most new OEM rotors today have a surface finish between 30 and 60 inches RA (roughness average), with many falling in the 40 to 50 RA range.
Why are my brake pads and rotors not working?
If your brake pads and brake rotors become glazed over this can cause your brakes to not work as effectively as they used to.
What should brake rotors look like when they need to be replaced?
Now that you have seen what brake rotors look like when they need to be replaced you should know what new brake rotors look like so that you can compare yours to new ones that way it gives you an idea as to how worn your brake rotors are. New brake rotors should look like the brake rotors in the below picture.
Why do I have vibration in my brake pad?
The vibration that you are feeling is because the brake rotor surface is no longer smooth and flat which causes the brake pad to pulsate as it runs across the surface of the brake rotor.
