I have a 05 montana that I have had back to the dealer 6 + times for grinding rear brakes. The dealer says this is normal as it improves some after the brakes warm up? I sounds absolutley terrbile from inside the vehicle I have run out of ideas?

Was told the same by the dealer...no noise after warm up tho...
maybe because it takes 6 years to nearly eliminate this prob ?

wheel cylinders might not be getting fluid pumped in.

Is this just in the am, or when backing up first thing cold, if so it seems this is caused by condensation on the drums that generates this groaning, haven't seen a permanent fix yet.

I've noticed the very same thing on my 2003. The brakes sound like they're dragging for a short time when you start driving after the vehicle has sat awhile, or first thing in the morning, etc. After about the 2nd brake application, it is gone.
I've inspected the drum brakes, and blew out all the brake dust, but the noise continues. The brake linings look just perfect, but the drum "might" look a little glazed, but nothing out of the ordinary I don't believe.
I wondered if the shoes and drums are sticking slightly when the car stops and the brakes cool off. Then when you take off after they've cooled, maybe the shoes stick, then release, and then they're slightly out of position and rub, but reposition to the right "non-rubbing" location once you apply the brakes one or two times.
Well, that's my guess.....maybe a different shoe material would eliminate the problem, but to be honest now that I know there isn't a leaking cylinder or a glazed shoe, I'm learning to ignore it! Glen

I replaced a leaky one but the noise was no different.

I do recall something about condensation now that you mention it.
Mine is in the AM when stopping for the first time only.
I'm learning to ignore it!
Same here:grinyes:
I really can't complain if this is one of a few minor but annoying problems.
See this topic for my #1 annoying problem :rolleyes: :
