Metal on metal braking

Hi there,
I have a 2011 Ram 1500 with the 5.7L HEMI and 4x4. I recently had an issue of spongy braking, so I took my truck in for an oil change and what they call "Piece of mind" servicing, which checks your brakes etc. I was told that the rear brakes had somehow reached the point where there was metal on metal contact, so my pads and rotors needed to be replaced. My truck only has 56000 kms on it, and the brakes were from the factory. I had the "Piece of mind" service done 10000 kms ago in August, and the report listed both front and rear brake pads at 7mm or more, so I am wondering how it is possible that this happened.

It's probably not possible and you got taken by some fool on commission.

Did you ask for them to show you the worn beyond limit pads? That would answer a lot of questions.
When they get to 1 mm is when they need to be replaced according to service info. If it is near that limit and your going on a road trip, then you should have them replaced.

I didn't ask, but I know for sure that it's highly unlikely they would go from 7mm to 1mm in 10000kms, unless something weird was going on. I guess I'm wondering if it's possible for that to happen. They said that sometimes the pistons get stuck and cause the caliper to contact the rotor, but I don't really understand how this could happen so quickly.

That is why you need to look at it for yourself to see if it is actually out of limits. You need to look at both inboard and outboard pads. Maybe the last shop that did the "peace of mind inspection" miscalculated the amount of wear. If the rears are prematurely wearing out, they need to make sure the calipers are not hanging and the hardware is good.

Ya, unfortunately it's too late to look at them. I had the service done at the same shop (Dodge dealer where I bought the truck), and I have the service records, so I guess I'll have to go have a conversation with them Monday. I just wanted to know if it was even a possibility. Thanks everyone

Where the old pads worn evenly? I guess it could be possible if you have some sort of mechanical problem in the rear brakes, some type of design fault, or the fronts aren't working all that great. Heavy braking driving around in mountainous regions, driving around with your foot resting on the brake pedal, and/or hauling heavy loads all the time could decrease brake life faster also. Lots of variables.

Well it's not due to hauling, or riding the brake. I do live in BC, but I'm not driving up and down mountains that often. The weird thing to me is the fact that the pads were at 7mm 10000kms ago, and the service was done by the same shop. I didn't get to see the pads, nor did I get a really good explanation about the cause from the service person. There was some mention of the pistons getting stuck due to dirt etc.

They made no recommendation to repair anything beyond the pads so they likely didn't see anything like that. I'm still thinking that either the first guy missed something or the second guy exaggerated.
