2013 Rogue S - Rotor suggestions

[RogueCP]

Hi all,

I currently own a 2013 Rogue S - My front and back brakes were replaced about 2-3 months ago. The last few weeks my brakes have been squeaking randomly as I apply pressure to them. I decided to pull the tires off to see maybe if the metal backing plates needed to be greased or if anything stood out. When I pulled the back wheel off, I noticed there are fine grooved towards the center of the rotor not deep at all but apparent to touch the router is smoother everywhere else. On the front rotor as I rubbed my finger across it, I felt similar grooves throughout the whole rotor. My rogue has 43,000 miles on it.

Since these grooves are not deep at all, does this effect performance in any way? I was always under the impression the rotor should be like glass when you run your finger across them. My car is not vibrating at all not pulling to any side or anything. The only reason I took the tire off was that sound which has not even been happening the last few days. I am going for a 3 hour drive and making sure all is well. Thanks for any and all help

The pads are made of particles pressed together, and some of the particles are pretty hard. When the rotors get hot during braking, it softens the metal enough to allow the 'grooving' you mentioned from the pads. The pads are more heat resistant because of what they are made of (asbestos, ceramic, etc.), so they withstand the heat better than the rotors, and produce the grooving in the super-heated rotors.

Unless the pads get down to the rivets and cause deep grooves, I don't worry about 'turning', or shaving the rotors during every pad change. If the rotors feel smooth, I leave them alone. Let the flaming begin now on this forum.

Incidentally, slotted and/or drilled rotors help to dissipate heat in the rotors, allowing them to cool more quickly. One tip my dad gave me was to let your call inch forward after coming to a hard stop in traffic or at traffic light - like after exiting the interstate. When the rotors are still hot, by inching forward while waiting for traffic to move or the light to change when the rotors and pads are still hot, you keep the pads from staying on one spot on the rotors and possibly causing a soft spot that could warp. By rolling just a smidge, you keep the pads moving around the rotors instead of staying on one spot.

IF the previous pad has slightly cut into the rotor the new pad will wear into that shape and continue the grooved wearing. That is why you SHOULD have rotors turned when installing new pads. It creates a fresh new surface for the new pad to bed into.

It may indicate also that your brake 'hardware' (clips and slides) are not lubed properly. The pads aren't moving freely enough in the slides, getting stuck, then moving abruptly when the pistons apply pressure. Most instructions call for replacing this 'hardware' during every pad replacement, but I think a good cleaning with a metal brush and brake cleaner is good enough, then follow-up with the proper brake lube or grease. The grease should also be applied to the back of the pads where they contact the pad backing plate, and also the tabs on the pads where they fit into the guides.

Also, or alternatively, the spring that holds the pads in place could be mounted improperly. If so, it can keep the pads at some weird angle until the pistons press them, and then cause that noise.

COULD BE JUST DIRTY BRAKE PAD AIR CHANNELS. HAPPENS TO EVER CAR. SEARCH THE FORUM, OR VISIT MY YOUTUBE: WWW.YOUTUBE.COM/IMSTRICKEN06 TO SEE VIDEOS HOW TO CLEAN PADS. ITS THE SAME PROCESS ON ALL CARS.

NORMAL. ROTORS WILL NEVER BE PERFECTLY LEVEL/SMOOTH

NO

YOU'RE WRONG. (maybe when brand new and not installed)

grease your slider pins, clean your pads, and grease the contact spots. see my channel for how to's
