Hey guys,

All new brake components under 10k miles ago. A rotor is warped. How do I find out which one it is? I was pointed out some funky wear on the passenger side front, but now it's not as uneven as it looked before. I'm going to replace all flex lines when I replace the rotor and caliper on the has spot. I can take pics if need be. Definitely feels like its in the front. The whole truck shakes coming off the highway. Town driving the pedal pulses and truck takes longer to spot and the warping is obvious. '04 2wd

 

Bump

 

IF you feel the hammering in the steering wheel as well, I'd say definitely the front, if not, then maybe the back if you have 4wheel disc...

As far as left or right, I'm not sure how to tell other than visual inspection.

 

You'd need to mount a dial indicator on the bracket and put it on the surface of the rotor and spin it and see how much deflection it has.

But in theory you're supposed to replace brake components in pairs...

 

It rattles the wheel. I've already replaced them, it's wasting my money. Only the bad side is getting replaced. I just did it lol

 

Is that a tool I can rent pat?

 

doubt it

 

Damn I might just have a shop do it then

 

Do you tow? If so, how much weight?

I don't tow but I'm going to replace my rotors with cryo-treated rotors as I can tell they won't last and I'm very easy on my brakes and truck in general. Cryo-treated rotors are much more resistant to surface damage caused by heating and cooling of the rotor which helps introduce the warped effect.

No towing, I think a flex line is failing.

 

Do you torque your lug nuts to specs (150 ft lbs)? If not they are almost guaranteed to warp. Since I started doing that, it has been 20 years since I have had a warped rotor.

 

I've warped rotors at the car wash before spraying the rotor when its hot is not good. Also its important if you have rear drums that they work right. Other wise your fronts get to hot doing all the stopping. You can usually feel what side its coming from in the steering wheel shake on the right-right rotor or if you jack it up and spin the wheel it catches..

 

Thanks for the help guys. I'll try to do the spin test. I just want to make it clear, I had a complete brake job less than 10k miles ago. Calipers, rotors, pads all around inclduing rear parking brake assembly. Flex lines will be replaced too this time around. I also have smelt the seized caliper smeel here and there. This happened on the passenger side front before, so that's another reason why I think it's that one. I wasn't sure it if was my truck or not since I was driving, but I'm thinking it is.

Lug nuts are torqued by hand, but they are real tight, never had an issue before. One rotor is a motorcraft (drivers side) the passenger is a raybestos.

 

If you had it professionally done check your paper work you might have a warranty.

 

I thought of that, but I did not have the calipers done by the dealer, just one rotor as I had recieved a defective one with a bad pulse ring.
