Hey all, I'm wondering if anyone else has had this problem with their rotors..... Last year in august I noticed I could hear a slight rubbing or grinding at a very specific time. It only happened when I was braking and would let off the brakes and coast at about 5 MPH. Then I would hear a grinding type noise coming from the front wheels (unsure which one exactly). It sounded like there was a rock embedded in one of the rotors and, as the wheel rotated, the spot on the rotor with the rock would grind up against the caliber.... not very annoying but concerning to me definitely. So I took it in to the dealer as I was at about 35,800 miles just under warranty and they said it was a warped rotor. They said they fixed the problem and that was that. I didn't hear it again all fall, winter, spring, and this past summer. Now I am hearing it again....

Could it be the same rotor and maybe it's defective and needs to be replaced because them "fixing" it last year was just putting a band-aid on a knife wound and it was bound to happen again? OR is this a recurring issue with these trucks and the rotors?

Note that I do not do any heavy off-roading or otherwise "non-normal" driving...

 

I bet they re-did the bedding process, otherwise known as hammering the hell out of it with hard braking to clean off the pad material. No such thing as warped rotors.

To answer your question...YES. Ford has had problems with warping of rotors on their trucks for years. My 1997 F150 and my 2001 Expy both had huge problems with warping until I bought HD rotors from Napa. My current 2014 SCrew had warping at 16K miles until I put PowerStop Z36 systems. The problem is the Ford F150 platform is too heavy for the cheap materials in their OEM rotors. After reading many forums, it seems like it is a luck of a draw thing with rotors with some owners not having problems with warping. But in my case, 3 of the 4 Ford trucks I have owned had rotor warping issues...only truck I did not have a problem with was my 03 F250.

My 2011 F150 had a warped rotor issue. I had to take the fronts off several times and took them to a local auto shop to have them turned (only $20 each time). My 2016 however hasn't had the issue.....yet. But i'm at 48k miles too. I'd try the rebedding process first to see if that alleviates your issue.

 

You need to evaluate your driving style. Specifically, things like keeping your foot on the brake after a stop, especially from high speed. Stop short, then slowly roll forward. What you're experiencing is pad material being deposited on the rotors, and it happens because you're holding the pads in the same, super-heated spot on the rotors.

I've run my F150s pretty hard (ever had smoke rolling off your brakes?) and I've not experienced "warped" rotors or braking vibration, especially in anything from 2010 on (when Ford redid the brakes).

 

knocking on wood....haven't had issues with my '16. About a year after buying my 04 Titan, there was a TSB/Recall for warped rotors, and Nissan installed bigger/thicker rotors. I do believe that driving habits can play a role in how fast or if your rotors warp. God love her, but my wife tends to brake 'late' and put a fair amount of heat in the rotors and they start to shudder. I had them turned and then did a 1500+ mile trip to/from the Smoky's including up and down mountain roads and they never caused a problem. Less than 6 months later, they are getting wobbly.

 

Post #2 is the answer. Furthermore, I would have no faith in any mechanic who claimed I had a warped rotor unless he could also give me out of spec runout numbers. Rotors can in fact warp, but almost none of what is diagnosed that way are in fact warped. Warped rotors cause excessive pad knock back, which manifests itself as excessive pedal travel. A warped rotor will also cause excessive pin wear on a floating caliper. A pulsing pedal is not a symptom of a warped rotor, neither is noise.

 

mine "warped" at about 35-40,000 miles. they had the classic vibration in the wheel when braking. i had them replaced, no problems so far on this set, im at almost 60k. first vehicle i had ever had to replace the rotors on.

 

It is like pulling teeth trying to dispel the warped rotor myth. People cling to that like white on rice. Ah well.

 

Brake pad deposition, which is entirely due to driving style. Rotors don't 'warp'.
