Brakes Pulsing

Recently when I first start driving our 2006 Grand Cherokee Overland, a pulse sensation appears. This occurs only when the jeep has been parked for maybe an hour or more. Transfer case lub condition looks good as well as the transmission. It seems that the brakes (front) are being applied without my intervention. After driving a half block or less the vehicle acts normally. Since I have a 1300 mile drive ahead of me next week, I think I need to get this issue resolved.

No indicators or lights. Turned off anti-skid.

Re: Brakes Pulsing

Possibly the parking brake or brakes are sticking in general when you first park the vehicle. Leaving it to loosen up after driving for a minute. Is there any squeaking or rubbing sound along with the pulsing?

Re: Brakes Pulsing

I apologize to those that have responded. I am learning that the transfer case is the issue. Problem appears mostly when vehicle is first driven after sitting for an hour or so. Making a left or right turn accentuates the problem until after the Jeep is driven a minute or so. I have taken it to a good service garage where we checked the fluid and found it needed to be replaced. Fluid was purchased from a Chrysler/Jeep dealer and installed. We will see how the Jeep responds to the fluid change tomorrow.
