In looking at my front rotors I noticed what look like lots of tiny little hair line cracks about 1/4 long.. are these stress cracks from overheating etc.?? If so is it a known problem with our trucks?

Thanks, Mike.

I would replace them. Thinking about it, I would say overheating. But, correct me if I am wrong.

Just heat cracks. A quick spin on a lathe takes them away.

If you have them turned ask them if it will remove at least the whole face of the rotor. I took some in this week and they said they could only take .010 but when I got it back, only half of the face got turned, the other half was still worn and grooved :thud: I tried to use it, but sure enough, it was bad and the truck shuddered like death wobble until I replaced it :CRY:

If you go for replacements, go for $$ quality. I had mine replaced, probably off the shelf made in China crap, and they are already warped again.

That's what I was always taught, buy the best rotors money can buy and the cheapest brake pads you can find (so they won't eat your $$ rotors). I learned that lesson when I was 17, I bought some super duper titanium brake pads from JC Whitney. They worked great (for about 6 months) and when I pulled the tire to check the pads they were in near new condition, but my rotor was nearly gone. oops!

Cracks are from heat... I would attempt to turn them as long as they are still in specs. (Safety issue!)

Then I would highly suggest you get a Exhaust Brake. I've got over 125K miles now and still got better than 50% of my stock pads left. Basically it allows you to do most of your long down hill stopping with the exhaust brake keeping the wear and heat off your service brakes till you really need them...

Yep, heat cracks. I've never had a Dodge rotor turned. On GM's, you can usually turn them once and then you have to replace them. GM's are really bad about warping, so turning typically involves a lot of material being removed.

I always run the most expensive pad I can buy. Usually wagner thermo quiets. I tried the cheap pads for the above listed reason and it DESTROYED my rotors. Cut big massive grooves in them. So I had to replace all 4 rotors which in the end costed me a ton. I put the expensive pads on and I've never had another issue.

Yup. Mom's brakes on her 04 dmax were warped after 110k miles of driving and pulling trailers. Pads were also cracked but they were stock pads with 110k miles on them. She didn't believe dad and I until I pulled them off to have them turned.:thud:
