New brakes and weird sound can’t pinpoint

duckman631 · May 10, 2024

2016 Ram 4x4. Had new raybestos e coated rotors and Wagner oex pads all around installed a few hundred miles ago. When coming to a stop slow, fast or hard and more so when it’s on a downhill with the weight of the truck, I get a sort of grinding/slipping the grip noise seemingly from the front. Not a grinding like there is something between pad and rotor but more of a slipping sound. Like it’s gripping but the rotor is slipping while it keeps trying to grip. Was butter smooth and quiet with old pads and rotors. Any thoughts where to start? Hard to tell but sounds like it’s all in the front and can’t determine if it’s both sides but can hear it on drivers side.

Did you follow the procedure for bedding the new pads? You didn't mention so had to ask?

They did or at least they said they did

I have installed a couple of sets of these, and I've gotten weird grinding noises on both vehicles. I did a bedding procedure for my wife's car consisting of several hard, hot stops. Pads and rotors were toasty after I did this. That took care of almost all of the noise on her car, I still hear some when backing up. My Ram makes a strange grinding noise once after sitting for several hours that I suspect may be the brakes. The OEX seem to stop well, but I've had some noise issues.

1. Bed-In Procedure For Street Pads

Accelerate your vehicle at 60-70kph (40-45mph) and gently brake the vehicle to gradually decrease the speed to 20kph (10mph).
Accelerate the vehicle again to the same speed, followed by applying the brakes again. Repeat the step 3 to 4 times. This will bring the brake rotors to an optimum temperature.
Now speed up the vehicle to 90-100kmph (60-65mph) and apply the brake comparatively harder to bring the vehicle down to 20kph (10mph). Repeated this step 6-8 times.
After carrying out the above steps, drive your vehicle around for 10 minutes and allow the brakes to cool.
Repeat the process again and apply brakes 3 times (from 70kph to 20kph) in succession, followed by back-to-back 6 to 8 heavy braking (from 90kph to 10kph).
Drive for another 10 minutes on an empty stretch without applying the brake. This will bring down the temperature of your brakes.
Avoid applying the brakes of your vehicle to a complete stop while carrying out the break-in procedure because the brake pads and rotors are hot. Stopping to a complete halt might allow the hot brake pads to leave an imprint on the rotor surface, creating an uneven surface.

And do this where? I have no where even close I can effectively perform these maneuvers with no one around.

I just gave you a link to the proper procedure,it's up to you to find a road you can do it on.I find between 5:00 and 6:00am on Sunday mornings to be a good time to find a road that won't have normal traffic on it "yet". If you don't know of anywhere to bed in the brakes properly,what makes you think the shop you used,did a proper break in procedure to bed the brakes,as i'm guessing they'd be using the same roads as you would be.

Get up real early ,when the neighbors are sleeping.

I thought the same thing about the shop after I heard about the procedures like above but on the Wagner site the procedure they also advise is to get up to 30mph then come to a stop and repeat 20 times. That seems more doable around here so shop may have gone that way. I replaced entire suspension so I’m dropping it off Sunday for a 500 mile retorque of everything underneath so he will take a look at brakes too.

Don't know if i agree with Wagners break in procedure,as i've never seen any other outfit reconmending coming to a complete stop when bedding in pads.I know i sure as hell wouldn't be coming to a complete stop while breaking in a set of pads and rotors,as that makes for a hot spot on the rotors.There must be a back 2 lane road you can get on at 5:00am Sunday morning to break in the pads.

I did most of the above and a few modifications to it but they are definitely better. Coming to a stop at the end of my road which is a significant hill, they aren’t seeming like they are slipping now and not hearing that noise either.

Do you have any Mall outlet with allot of parking lots, go there in the early AM hours usually nobody around, this procedure words, you have to break a few nuts to get nut jam!

I performed the Wagner break in with the OEX pads on all four corners. Thus far, they're working fine.

Nowhere local enough with a large enough lot. I think some of the process I did while out driving on local roads may have helped.

and hope a cop doesn't suspect you of driving under the influence.

Hi. Going to defer to your expertise. I took the truck back to mechanic to retorque all the suspension components they installed as a 500 mi follow up. I had him pull all the pads. He said they were glazed. He said he scuffed them up and reinstalled to see how they do. My question is… is it possible to rescue them and have them be ok going for or are they pretty much a loss once they get glazed. They had less than 500 miles on them and the braking was minimal within those 500 mi. Thanks!

do you have any country roads!? i live in the city and with in a 10 to 15 min drive i am in the country side roads so i can do this! I put slotted cross drilled rotors and ceramic pads on all 4 corners of my 1500 and had to do the same thing! now they work great with no issues !

They should be okay,but you might want to re-bed them in again.

Thanks! I wish he had told me he was pulling them all. I would have just had him replace with something else.
