brake pads

Anyone have part numbers for rear brake pads for a 1999 E450 super duty with duallys. Seems Rockauto sold me a set of Monroe CX 802 that dont fit. Probably head over to NAPA local store and it would be nice to have part numbers to help them out. thanks Al

    The 'brake lines will look perfectly fine' BUT they fail on the inside. The inside collapses.

    Been there did that. Replaced the brakes only, on the same make and model you have and coming off an interstate ramp and the brakes went out. :E Thought for sure I was going to die.

    Truck stop repair knew right away it was the brake lines. Just saying since you've got it apart I would replace the brake lines also.


    You are referring to the "RUBBER" soft brake lines only ? the Steel metal usually have no issues unless vehicle is operated in salt conditions and rust has pitted the outside OR if the brake fluid is not flushed at proper intervals & moisture has collected & has rusted from the inside

    Yup the rubber ones and you have to buy OEM for them. I had one day layover waiting for them to ship overnight. But real glad that semi- truck mechanic knew that that's where the problem was. He said everyone should change them out period.

    And I had just had a complete brake job before I hit the road for that trip and that mechanic never said anything about replacing them. Dang near died coming off that ramp towing without brakes!! :B

    We had a left front brake flex line fail on our previous Chevy powered '79 Delta Class C , as you described, it almost threw us off a cliff on US 101. It would be good to know how often flexible front brake lines should be replaced for safety sake.


    Unfortunately, the industry usually replaces brake lines based on a visual inspection or performance complaint and there is no standard replacement interval. In the old days, the flexible lines were supposed to be inspected every time a "mechanic" was under the vehicle during the standard service interval. (6 months or 6,000 miles) Nowadays, that doesn't happen. (unless you do it yourself or specifically request it)

  • If you do go the NAPA route bring an old pad with you and verify the replacements are correct before you purchase them.
  • Brake pads I replaced on my 2006 E350 were Motorcraft (From Rock Auto) Heavy Duty "Police / Emergency" versions. There was a visual difference between the OEM & the Ones I replaced with.

    If I need to do another replacement & can't find the same Pads, I would look at AKEBONO mfg. (They are the OEM supplier to a high number of Auto Mfgs.) Have used them on daily drivers. Raybestos Heavy Duty / police duty would be a good choice.

    I have slotted / cross drilled rotors & Ceramic / Carbon pads on one vehicle but would Never do this on a RV.
