This past weekend installed some new rotors and pads on the Crown Vic. Noticed a little bit of squeaking noise as I'm driving. How long do you guys typically notice that the noise last before they're fully bed in?
New brakes bed in noise, how long does it last?
- Thread starter panthermike
- Start date
Did you clean the hubs where you mount the rotors? Did you need to spray brake cleaner on the rotors to take that oily surface off? Did you clean the calipers? How about lubing the ears of the pads and back of the pads?
If it is making nose while driving (and not braking) there is an issue that needs to be addressed. Most likely the hardware is out of place.
all questions I had but I wanted to assume he knew how to correctly do a brake job.
I think its likely that something needs lubed or adjusted.. you can get sandpaper type noises off new coated rotors.. but squealing isnt usually part of the bed in process.
otoh the rotor and pad material matters to.. info we dont have.
Squeaking is not part of the bed in process. As others have noted - something else needs to be revisited in the install.
When we put original hyundai (semi-metallic) pads on hyundai rotors, they were silent. If we used hyundai pads on Bosch rotors we got squeaking under braking. I don't know if the casting of the rotors was different, if they used a different material or what else it xould be but the squeaking never stopped unless either pads or discs got replaced (by bosch pads or oem discs).
So it could just be the particular combination of parts you are using. Best advice is to double check everything is right though

Damped iron has some noise control properties. Most likely, the Bosch rotors were plain G3000 steel and the Hyundai rotors were not.
I was gonna say this. And there are two sounds, squealing, and groaning, which are different.
If this were a car with metallic pads it'd be imho more feasible? But I would think this car has ceramic or asbestos (dunno what the term is under ceramic) if you will pads....
Thank you for the replies.
I did clean everything but did not apply grease to back of pads.
I did have to clean one rotor with brake cleaner.
Definitely could be hardware!
Raybestos rotors and Wagner Ceramic pads.

It could be piston to backing of pads, where there are usually shims built in, but there's a paste that can be applied....
Toyotas sometimes have shims that have been discarded by a previous brake job, there are 2 per pad or 8 per axle. mine are missing so there's a thud when applying brakes because there's ever so more play than with the shims....

I remember printed on the box of auto zone gold rotors
==Built from advanced materials and specially engineered to reduce noise
==Higher carbon steel delivers maximum heat dissipation and improves performance
Not a huge fan of auto zone ,but those Gold Rotors were Quality!

Also forgot to mention in my last response, it is definitely more of a squeal and a very very light one at that. I can only hear it if the windows are down and I think most people probably wouldn't even notice except for us car folks
Update to this:
So by the end of the day yesterday, it seemed as though the noise was less I could barely hear it. However I still decided to take off the tires and have a looksy. Everything looked good, hardware was in place. While I was in there I cleaned parts again and added the grease that I should have done the first time. I'm wondering if the noise actually was The brake pads? So what I did was turn the rotor by hand and could hear a faint sound wouldn't even call it really a squeak, just the sound of pads against rotors. Once the brake pads were off, I turned the rotors again and no sound. So perhaps it is just the pads breaking in and I have very sensitive hearing?
Either way I think it's okay everything looks good and brakes are working great with no shimmies or anything. I'll just keep on motoring. I'll return to this thread if there's any issues or when the noise dissipates completely

Problem solved! Turns out when I was doing the brake job one of the rivets on the dust shield had broke off. I zip tied it temporarily to keep it in place and forgot about it. Well today while I was driving home from work the noise got really loud and noticeable. Went home took the wheel off checked everything out and The zip tie had broken off and I could tell that the dust shield had bent just enough to get into contact with the rotor as it was turning. Thankfully no damage done or grooves or anything.
Kind of a strange one but glad it presented itself today as I am heading off tomorrow morning for a 1500 mile drive
