What Causes Grooves In Rotors?

Grooves On The Rotor Over time, grooves will naturally develop on the rotor from repeated contact with the brake pads. But these marks take away from the part’s capacity to slow the vehicle, as well as cause vibration and pulsation that can be felt in the brake pedal.

Is resurfacing rotors a good idea?

Resurfacing rotors help eliminate corrosion and brake pad deposits, which smooths out surface irregularities that may cause braking vibrations. It's a brake service procedure that typically accompanies a brake pad replacement to create a 'new' surface for maximum brake pad friction.

What causes scoring on rotors?

Scoring usually occurs when the frictional material on the brake pads has been worn down severely. Once this “padding” is gone, the underlying metal scrapes against the rotor during deceleration. Over time this can lead to deep grooves on the rotor surface.

When can a rotor not be resurfaced?

Those severely damaged rotors usually need to be replaced, not resurfaced. Some vehicle manufacturers even require that you replace your rotors rather than resurface them. Otherwise, most industry experts suggest that you should replace them every 30-70K miles.

Can you resurface rotors with grooves?

If your brake rotors have sufficient metal remaining with no hard spots, cracks, severe grooving or rusting, then the rotors could be resurfaced. Some have the opinion that unless the brake rotors have surface issues needing to be fixed, the rotors should not be resurfaced every time the pads are replaced.

Can you resurface rotors with holes?

Can You Resurface Drilled & Slotted Rotors? It is possible to machine or cut a drilled & slotted rotor. To do so, the brake lathe should be set to its slowest setting. Whenever brake pads are replaced, the rotors should also be replaced or resurfaced to allow the new pads to be properly bedded.

How often should I resurface my rotors?

Even resurfaced rotors need to be replaced every 70,000 miles, doesn't matter that they are in good working condition. Look for signs of uneven wear, excessive runout, and heavy pitting, spotting, grooving, hard spots, or cracking.

The Symptoms Of Warped Brake Rotor Explained.

Can pitted rotors be resurfaced?

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.

How do you know if brake rotors can be resurfaced?

If your brake rotors have sufficient metal remaining with no hard spots, cracks, severe grooving or rusting, then the rotors could be resurfaced. Some have the opinion that unless the brake rotors have surface issues needing to be fixed, the rotors should not be resurfaced every time the pads are replaced.
