| I parked my 2003 EX for couple of months. I was starting the car on and off while it was parked. I never take it out from the garage. This afternoon I take it out and drove a little bit and I noticed a sound/vibration as if something is touching from the rear end. This sound is noticeable at lower speed. First I thought its brakes, however i hear this sound regardless of pressing brakes. Any ideas? |

| Is it rhythmic? Could it be that the tires have a flat spot from sitting so long? |

| Sounds like flat spotting to me to. |

thanks for replying....I'm not sure if the sound is rythmic...but its constant...as if something is rubbing at the back...i also inspected the reak brakes...and i see black greese type material....could it be wear on rear brakes?
how do i make sure if its a case of flat spotting? |

| one clarification...when i said rubbing sound in the back..i meant as if something is rubbing against each other at the rear end... |

| the e-brake or the emergency brake which is a disc type that is inside the rear rotors. try to engage the e-brake "lightly" and see if the grinding gets worse then better eventually. |

Make sure that your tires are properly inflated. Flat spotting should go away or get better as you drive the Pilot.
I get this on my truck when I don't drive it for a week or two. Usually goes away within a mile or two. As your Pilot has been sitting longer, it may take a bit longer. In the future, it might be a good idea to drive it a little more often instead of just starting it up. |

Sounds to me like it's just oxidation on your rotors. Get it up to highway speed and do some moderately hard braking. Don't slam on the brakes and crash, but don't be afraid to get on the pedal a little. If it's oxidation on the rotors that ought to take care of it.
With modern tire technology, flat spotting shouldn't be an issue unless you live in a VERY cold climate, you know, where parking lots have electrical outlets for you to plug in your block heater. My toy vehicle, a 75 Blazer (very clever user name if I do say so myself) only gets about 1000 miles/year. Needless to say it spends A LOT of time sitting in the garage. I have NEVER had any issues with flat spotting, not even in the cold Chicago winters.
Also, I agree with Sblvro, except the parking brake is a drum brake inside the rotor not a disc. Those pesky little drums have a tendency to stick with just a little bit of corrosion. I gently ride mine for about 50 feet or so once a month just to keep things clean. |

Did you have the parking brake set during the period?
Not a good idea to leave the parking brake set for long periods. Not really a good idea to use it at all if you're just parking in your level garage.

Why not? |

Because the mechanism and cable will tend to corrode and stick in the set position, especially if you use it after it is wet or cold. And you'll get more stretch in the cable and return spring by leaving it tensioned all the time, leading to more frequent need for adjustment.
I'm not saying you shouldn't use the parking brake and I use mine whenever I park on anything but perfectly level ground away from home. Obviously on a hill, it is absolutely necessary. But parking in your own level garage? Totally unnecessary as the parking pawl in the transmission has plenty of power to keep the vehicle stationary so why not avoid the wear/tear?
