Brake Question - 2005 Dodge 2500 2x4

Truck: 2005 dodge diesel 2500 Quad cab with 80K miles

I had the brake pads replaced the other day
rear pads were about gone, front had more pad left, so they must have been replaced before I got the truck at 40K

we did not replace or turn down the rotors: truck had no brake vibration before pads were replaced.

after replacing the pads, the truck started having a vibration when stopping like the rotors were warped, so my mech replaced the front rotors and dressed down the new front pads.

still picking up a small amount of vibration when applying the brakes.

The mech thinks it may be the rear rotors that are warped.

I ask my auto parts supplier about this,

he said that many of the trucks that pull heavy loads like campers, equipment trailers, cattle trailers, most all will also replace the rear rotors.

He ask, is the vibration in the steering wheel or the body of the truck, I said body of the truck, then he said that was the rear rotors!!!!!!!!!!
if front rotors were warped the steering wheel would be going back and forth in your hands each time you applied the brakes?????.

I am not so sure at this point what to do as the rear rotors are about 1/3 more cost than the front rotors.

have any of you heard of this before ?????????
having to replace the rear rotors to stop a brake vibration.

planning on pulling out for a trip this weekend, my bumper pull camper only weights about 6K, so I am not going to over load the old dodge, just want to be safe.

Thanks for any input,

  • After driving check the rear drive line ujoints with an infrared heat gun. Be sure they are OK. When my middle ujoint went bad it still felt solid on the truck. After driving it was 10deg warmer than the other two. Wouldn't hurt to verify before spending more money. You probably have a large drive line carrier bearing too.

    Sounds like the previous owner did all city driving. My 06' with about 102k miles still has over half brake pad life.
  • Make sure the lug nuts were properly torqued. Uneven clamping forces can warp rotors.
  • Hello Issue: Have you check the rotors for glazing. I have run into this problem twice.
    I also ran into a problem one with heat checking of rotor faces (front only).
    The biggest problem for me was the brake system was to little for the truck, and load requirement.

    Brake system was changed to correct.
  • Rebed them...

    Here is a good thread about curing new friction materials...or do a
    search using: brake, bedding in

    Most all say about the same thing, though there is a slight difference
    on HOW2 between regular vs performance vs race

    Don...didn't want to say it before, but now that you've indicated that
    you have glycol 5.1...it is a very good thing.

    ABS modules cost in the thousands of bucks and they have the same seal
    problems with silicone as normal OEM braking systems

    As for the other poster who said new pads had the warped rotor feel...it
    most likely is NOT warped rotors but a need to cure and bed in the new
    friction materials (pads)

    All friction materials need curing and when on vehicle brakes..the term
    is bedding in.

    The softer materials need more curing than harder materials

    What is most likely in your case is that you stopped moving when the
    friction material was still curing. Hot and outgassing to create a
    high spot on the rotor surface.

    Only takes a few ten thousandths of an inch to be noticeable on the
    brake pedal

    Do a search here and/or on the internet using: "brake bedding in" and
    you will find many methods. Most are generic, but there are differences
    between mud hen freebies that come with rebuilt calipers all the way
    up to pure track/race pads.

    This is one of the better explanations and is also my opinion on the
    matter. I also bed in my brakes differently, but won't list it here
    and best to use these folks. Hot link below
