Just like brake pads, brake rotors do not and will not last forever. Each and every brakes are applied, the rotors endures some wear and tear. How much they wear during each period depends on many things like type of brake pads, how the rotors cool themselves, type of driving that is done, the braking style, and weather conditions. Resurfacing rotors or replacing the rotors is two options to consider.
Resurfacing rotors is the most common way of bring your old and worn EBC rotors back to life. The great quality about EBC rotors is their ability to be resurfaced over and over again. Common with cheap aftermarket parts is they cannot be resurfaced due to the thickness of the rotor. EBC rotors are thicker than others which allow them to be resurfaced so many times. Most vehicles from the manufacturer are equipped with semi-metallic pads which can be a little harsh on the brake rotors. Using EBC rotors with EBC brake pads is the ultimate setup for increased stopping power and reliability.
OEM rotors used to be designed to withstand two or three pad replacements. But in today’s market, manufacturers are making them thinner and lighter to save weight and cost. On these specific OEM rotors, the part may need replacing after the first set of EBC brake pads is gone through. EBC rotors outlast OEM by thousands of miles. They are much thicker and heavier. Resurfacing rotors should only be done after measuring the thickness. If they are too thin, it can become brittle and crack under heat and pressure. Replacement rotors will be needed if this is the case.
Uneven wear can ruin the surface of the EBC rotors as well. There are many factors that play into this including uneven tightening or over tightening hardware when installed, dirt or dust between the rotor and hard spots from the casting. The surface will become damaged if any of these are true and resurfacing rotors will be required.
If you find out that one of your EBC rotors needs to be resurfaced, it is highly likely that the rest of them do too. Since braking is applied to all four rotors evenly, each specific part will see the same amount of wear, as long as they are all true and do not have uneven wear. EBC rotors will bounce right back to their original state without any compromising after being resurfaced.
Resurfacing rotors is when the initial layer of metal on the surface is removed. This contains dirt, debris, and metal. EBC rotors then become flat with a smooth surface just like they were out of the box. This provides proper friction characteristics, reduces noise vibrations and creates a maximum surface for the pad to grab onto. If you were to install new pads on worn rotors, it would create an uneven pad surface that would cause vibrations and weak stopping power. The pads will then wear down extremely fast.
Replacing your EBC rotors is more expensive than have them resurfaced. Resurfaced rotors cost about $10 or 20$ per rotor, where EBC rotors cost a couple hundred. Some auto parts stores also do the job for free. If you like your current EBC rotors, and just want them to perform like new, then have them resurfaced. Resurfacing rotors is done more often in this economy than it was before.
Inspection is a number one priority before resurfacing rotors. They may be fine and the brake pads are the only culprit. EBC rotors usually last a while before needing this treatment, so brake issues can either be related to fault brake lines, minimal fluid or worn-out pads. Replacement rotors are the last option as all other options should be checked first. Resurfacing rotors before they need it can make them wear out quicker than others. Outfitting your vehicle with products from EBC brakes will allow you to have confidence while braking. If you are taking off the brake rotors yourself, you will need four jack stands to keep the car lifted while you take them to a shop. The process cannot be done at home.
