Rotor grooves

Hi all,

I have a 2015 f250 extended cab, gas with 31000 miles. Its a work truck but its my day truck as well so lots of easy miles too. Checked the brakes today thinking it may be time for pads and found lots of grooves on all rotors, pads have lots of life yet. Is this common on the 2015? did ford give us low quality rotors? should I replace with less aggressive pads? I have had no braking problems, noise or pulsing. I thought I could put a second set of pads on the original rotors....
Thanks for any advice.

Ya the fact that the drivers side front is as smooth as a babies bottom makes me think the other three are lemons..........not covered by ford

Unless the rotors are warped or causing a drivability concern, I wouldn't worry about replacing anything yet. The pads and rotors wear together, so you shouldn't have really lost contact area where the grooves are.

Also, the grooves are usually caused by the pads having some spots of harder material mixture in them. Some aftermarket rotors are made of lesser quality metal and will be more susceptible to this condition.

Take it to the dealer for a look. At 3 years or 36000 miles you will be dropped like a hot potato unless you have a factory extended warranty? 5 thousand miles left. Check the E brake shoe anchor pins and backing plates. Get them replaced under warranty if the pins look like they are gona pull through the plates. Mine did at 50K! If you live in Arizona disregard.

The only high quality rotors left on the planet are high end aftermarket or exotic car carbon fiber/ceramics. All domestic OEM rotors are now chineasium junk whether factory or replacement.

The factory brakes will last the longest. Run them as long as possible if nothings wrong. Wear grooves are nothing to worry about unless they are deep. Dont use softer pads. Always purchase the middle level pads and the best rotors to be had. There is 2-3 quality levels of chineasium junk rotors. Low mid and OK junk. Hard pads accelerate rotor wear.
Aftermarket rotors made here do exist for a price. At least they did 3-4 years ago.
