You do understand that the brake pad wears against the rotor? The material is transferred to the rotor through frictional contact. Everytime the pad contacts the rotor there is a transfer of material, the loose stuff falls off (brake dust), the other portion stays with the rotor. Take a paper towel and wipe your rotor and you will see brake pad material...

The fact that your brake pads have to be changed when they get low makes this pretty apparent...

The factory rotors are really bad about doing that. It is just easier to replace the pads and rotors.

Don't get me wrong, I love my F150, it's my 10th Ford truck product. In the good ole days I bought a new truck every year regardless if I needed it or not. When I bought my 06, I bought my "dream truck". To me it's a Caddy or Lincoln with a truck bed. 0% financing helped make the decision as well. I will drive this truck until it has over 100,000 miles on it.

However... The parts vendors that Ford uses for these trucks suck! I have had 2 sets of wheels, 2 sets of tires, the steering wheel, the drivers seat cover (and the replacement is worn through as well) and the steering rack assembly replaced under warranty. The plastic bed rail covers have turned white from the sun as well. I'm guessing the brake rotor contact was too given to the cheapest vendor.

Thanks again for all the input folks!

Is this coming out of some kind of language translation software? What is the original language?

Good old Bill

Bottom line the more machining is done the thinner they get, and thus the quicker they warp. The truck bath thing while hot is not good. Am wanting to get on your butt, so I'll sign off with this. 183K front rotors turned once, I messed up and was on rivets, the backs have never been touched.

My ford Edge has gone 29,000 on her brakes so far Knock on wood, with no problem and they looked good at 25,000

My 2003 f150 went around 54,000 on the first pads rotors good, traded in at around 80,000 same frt rotors.

My 2008 4x4 with 35" tires I know I won't be as lucky it is going to take a lot more wear to stop and probably more rotors sooner

In San diego I have a good connection for parts one is for american and another for foreign parts

Brakes rotor warpage is usually caused by heat, excessive heat! driving conditions affect this.
Stop and go traffic, Cause more braking than open freeway driving
Living in a hilly area cause excessive braking,
quick stops or ridding the brake pedal. can cause overheating an unusual wear

San Francisco area would be a place you would see lees miles to every rotor replacment
Texas flat plain possibly a higher milage before rotors get replace
these are just examples.

here in San Diego I had this one cutomer who lived on Mt. Soledad in LaJolla. all there cars went through frt rotors and pads ever 11,000 mile on average. They lived on a hill.

I had a customer once that went through frt rotors every 4-6000 mile I wty'd the first set and then on the second set I went for a ride the customer drove.
Now when I looked at the brake rotors they were blued bad (heat dicoloration) but everything seemed to work fine.
anyway this guy started going down the road driving real aggressive
when he came to a light he didn't slow down until the last minute and then real hard. this went on for a few blocks. I finally said this is enough! there is no wty on your brakes I told him yoiu have bad driving habbits and that is your brake problem.

Sometimes brake wear is caused by the trafic you drive in, the area you live in, stop and go - kids to school, grocery stores, short quick stop and go . People don't even notice.
If you live on a hill for example going down round and round you mya apply your brake off and on but going up you don't apply your brakes as much but going up has gravity on your side and going down gravity is against you! you may find one side of your brakes wearing more than the other.

all this I have seem in various cases.

Anyone tried cross drilling their stock rotors to help with heat dissipation? I think I would spend a few extra bucks for some higher end rotors if mine got to the point of needing to be replaced.

Yes, I do.


You are getting warm.

And you are going to sit there, tell me there are over 100,000,000 cars in the USA alone is for argument sake that they too have portions on the discs. Wait, it gets better.


And that will stop the warp on a rotor is a huge variable all those or most of those say some of those have a warp going, but to say that amount of brake dust warps a rotor, I am going to buy some brake cutting equipment and clean up that part of the market that I am going to be rich and on rotor dust.

Yes, now do you understand brake dust does not make a disc warp or am I about to make the chaos look like kids play

If you are going to give out that kind of information as "BRAKE DUST WARPS DISCS" you need to sell that to me one more time another way is I will lay bricks over your theory you better explain yourself in exacting fact after fact is I have never heard such a theory of dust in the wind is a song. OK, that is a fact, and I agree.

Dust in the wind is I need a dial indicator times 100,000,000 discs times 4 all around.

Who here speaks the same language as this guy? Any interpreters around?

Heat is what will worp a rotor, Also one can see hot spots on rotors. Heat changes metal

On Some models of cars the over tightening of wheels can warp a rotor,

On the Volvo 740 there was a bulletin about over tightening the frt wheels causing warped rotors.
I have had discount tire pay for rotors on a customers car for overtightening. alway use a torque wrench on your wheels to be safe.
(Sorry its not an f150) --- this is my back ground -- The only ford I have had brake problems with was my 1990 f250 lariat 4x4 LEMON ALL THE WAY

ford experiance: 1953 truck, 1970 f250 2wd, 1975 f2504x4x, 1985 f350 4x4, 1990 f250 4x4, 2003 f150, 2008 f150 ( all personal trucks )

So if everything is working right on a brake system. All specs are good including the wheel torque and the rotors warped look into driving conditions as explained
