Creaking noise

[bluejay]

I hear a slight creaking noise when I lift off the brake peddle . I only hear the noise when I release the brake peddle after braking while rolling . If I'm sitting still And press and release the peddle I hear no creaking sound . I'm wondering if anyone else has experienced this . And I'm curious if just getting the bakes serviced at the dealer will solve the issue . Everything else with the brakes seem to work great. Any input would be greatly appreciated

My clutch used to squeak a bit, it now just sorta pops at times.
Sure it's the brake pedal? Coming from within the car or exterior? You've 4 wheel discs, so I'd examine the pads...

 

[bluejay]

It's definitely coming from outside . And the noise is only heard when releasing the brake peddle. Someone suggested that it could be the shim holding the pads into the calliper. All 4 pads have plenty of life left . So I guess I'm going to have to get dirty this weekend and use my Sherlock Holmes skills

My car does this as well. I only noticed about 2 weeks ago. And only heard it because I was next to a wall at a drive thru. It sounds like a creaking if I press the peddle in and also when I release it. I thought maybe it was low on fluid but it isn't.

Please keep us updated. I would like to know what it is.

That's the only way I can hear it too . That's why I haven't gone to the dealer yet cause I don't think I'd be able to recreate the noise when I'm on the clock. Also mine started about 2-3 weeks ago as well .

It's happening with my car as well. I started noticing it this summer. Lifting foot off the pedal makes that squeaking noise even when the car is parked. I'm also curious about what this is. Please share what you find out.

Its your front brake pads creaking. Clean up and grease the pad ends and it'll be ok

 

[Josh89]

Mine made the same noise. The pads are creaking on the sliders in the caliper brackets. I wash my car almost daily so I get the creak every 6 months and repeat the service to remedy it

Mine does that from the rear drums. I've opened them up and lubed everything, it went away while I drove out of the shop, then came right back. I only notice it with the windows down and I don't usually drive the Sonic, the wife never has the windows down and doesn't notice it so it's been left alone. I upgraded all the front brakes to camaro/encore stuff and it didn't change, i know it's the rear, but it's not enough to bother me, it's just noise.

The creaking noise that I’ve heard is not from the brakes. This noise happens when the car is not in motion. My sonic is 6spd. So when at the drive thru. Not moving. I’ll press the brake peddle and hear a creaking noise. Then while the peddle is still down and stationary , I’d let go of the peddle and hear this noise again. And if I were to pump the brake peddle slowly , I can hear the noise constantly. The car is still in neutral and not moving at all on a flat surface. Now I am trying to listen to where the noise is coming from and it sound like it’s coming from under the hood. It’s not a brake creaking. I did Check all of my brakes because of this but they are really good.

Mine was making the same noise as well pbkn1p, but I think it has sense gone away. I checked my brakes as well, all is fine there.

When I was installing my boost gauge and fishing the sender wire through the firewall grommet on the drivers side, I notice that the black plastic line going to the brake fluid reservoir (drivers side) was not fully seated on. After I pushed it back on fully I haven't really noticed the sound anymore, but I plan to look into what is causing it. If the noise does come back, I plan to look at this connection first to see if it is not fully seated again.

Do note that this line seams to be a press fitting line with nothing else securing it in place to the. I also did find a little fluid seepage on it as well.

Send a photo of the location for this fitting. I'm also experiencing this same exact creaking noise and It's driving me nuts since I always drive windows down. The sound is more prominent from the back of the car for me, so I was thinking my drums needed service. I also just did the Encore swap not too long ago, but the noise was happening before the upgrade.

The black glossy corrugated line, it was about 1/8" to 1/4" off.

 

[Blue Moon Sonic]

Idk why, but I feel like that is the line going to the clutch master just behind the clutch pedal. I could be wrong, but that's what it looks like to me. I'll be checking this after my shift anyways.

Edit: Nvm, That's exactly what that hose is. GM Part#:96887805. 10 dollar corrugated line for the clutch.

 

[Tormach]

Ya, I have not traced it back or looked it up yet so I am not sure what it goes to if its the break peddle, or the clutch.

I am heading home so I will let ya know if i am still getting that creaking noise.

 

[Tormach]

Well on my drive home I had no creaking noise from pressing or releasing the brake peddle.

Only noise I have left but know what it is is the clutch peddle making a squeaky noise but it just needs to be lubed.

Thanks Blue, def good to know what that line is.

I'm going to chalk this up for now as a random coincidence for now.

 

[Blue Moon Sonic]

Good good. Though, I would definitely keep on eye on that clutch line.

Meanwhile, It's time to do the rear disc conversion. The squeak is coming from the drums in back. Not really thrilled about this because of how much money was just dropped, but also excited at the same time for a bit extra stopping power and ease of maintenance down the road.

Thanks josh , that’s what I thought it was I’m gonna get that fixed up when I swap over the snows

No worries bud. I'll be servicing mine before the snows go on. Will be interesting to see how the car reacts to winters here with eibach springs

Did you check the guide pins holding the caliper to the bracket. Without a good cleaning and greasing with a silicone lubricant, they will bind possibly creating a click (if not seized) as it unbinds. Those pins tend to be overlooked in a lot of cases.
