I have read about the many problems with our brakes squeaking. I just did a brake job not to long ago. The noise comes from the drivers side. I replaced rotors, pads, and brake hardware. Yes, I lubed the pins. It started to act worse after I was stupid enough to not double check my torque on the bolts. The bolt that holds the caliper assembly located on the spindle/knuckle came loose. Heard a loud bang from the bolt falling out and hitting my truck. Boy am I dumb.... Kept riding with it like that because I thought I must've thrown something up with my tire. I then heard metal bang to metal when stopping. Before all of this I had a caliper piston that wasn't willing to be compressed. So I thought maybe the piston was at fault. Then I noticed the bolt was gone and replaced it along with new brake hardware and grease for my pins. Now it makes a consistent squeak when rolling down the street. I was too embarrassed to tell you guys. Know I need your help. Pads and rotors look fine. I have been under the impression that my caliper may need to be replaced. Any thoughts or suggestions will be much appreciated. I'm a prior aircraft mechanic not an auto mechanic! I'm just a DIY guy who drives it as a dd.

Thanks bros,
Mat g.

Most disc brakes have a metal tab, on at least one of the pads, that will contact the rotor and cause a squeaking noise when the pad is worn. Maybe the tab got bent when the caliper shifted while the bolt was out. As an aircraft mechanic (47 years), I learned to place a torque wrench in full view during maintenance, as a reminder. Mistakes like that are not good on an aircraft.

Just throwing this out there did you make sure to clean the new rotors well before install. They come coated in an oil to prevent corosion. That oil can destroy a new set of pads if not cleaned off.

Not an aircraft mechanic anymore. I usually go by the torque specs. I used a torque wrench many times and I am very familiar in how to use them. The cheesy one I have isn't working correctly. No i did not drop it but I do have a brother who negligently uses my shit and breaks it without knowing/is to afraid to tell me. I will take a look at the tab but seemed fine to me when I removed yesterday. Also, I can't recall cleaning the new rotors but thought I did. I will probably just try another set of pads just in case. I will be sure to clean the rotor before I put the new set on.

I almost have the script portion of this memorized. I understand the poster is likely employed by GM to post replies to this type of thread, however, it might be better help to create a thread that tells us how to contact GM Customer Care in the event of a problem with a dealership or that contacting GM directly may be useful. (i.e. We discover a safety defect in manufacturing that may warrant a recall or TSB or we discover a common problem in the 2015 model to address for 2016.)

Also tagging the GM account (if that still works) on threads where needed may work better.

P.S. opc:opc:opc: and :th_ontopic:

This thread was trashed quick. I did notice today that if I barely apply pressure whilst driving the squeak goes away. May get new pads and get the rotor turned. I'll see what that will do. If not I'll go back to my original hypothesis of replacing the caliper.

It's tough to say. There's the metal brackets the pads slide on, maybe a backing plate came off a pad when the caliper came loose, you may have bent the abutment bracket the caliper mounts to, rotor could be bent.

Jack up the truck, take off the tire and spin the hub to pinpoint the squeak.

If it goes away with slight brake pressure it may be the brake pad shims I've had all kinds of weird noises from them

Just replaced the shims. They are brand new. When I turn the rotor with the wheel off. I still don't hear any noises. I hope I didn't f up that rotor. I'll find out more next week when I get a chance. Thanks for the input guys.

If you have no noise without you applying the brakes then it is either a glassed over rotor, the metal sliders not seated properly(I know you changed them but you could still install them wrong and they should be greased with Amazon.com: CRC Disc Brake Quiet 05016, 4 Fl Oz: Automotive) or you have something up with a pad.

Take 220 grit sandpaper and scuff the pads good and rotor and reassemble everything paying real close attention and use the grease I linked above on the sliders and the back of the pads.

If the caliper can't be compressed I would start there, I just had to replace one of mine for sticking and it was causing the brakes to drag bad

 

[gunnyboy]

I use the crc brake grease. Bought it last weekend. Guys, I made a rookie mistake. Let's just say when I installed the new rotors at a friends house, he ran out of thread locker. He told me to go home and remove/install with thread locker. We were engaged in heavy projects that day and totally forgot about it when I got back home. With my 3rd shift work keeping my mind occupied, I lost my train of thought. So today I got under there and sure enough.... Rotor bolts had started to back out. I don't know why I forgot to check the bolts on the rotors. Hell, I had removed that side several times. At least it's fixed. I am surprised firestone didn't see it! I took it to them a few weeks ago and they told me to replace the shims..... It's all good now... Thanks guys for trying to help out my retarded ass.... Moral of this story.... Use thread locker or a decent torque wrench.

Maybe next time I'll have my head out of my fourth point of contact. So glad I don't have to hear that noise anymore. Now I can ride in peace....
