Think I got a defective caliper

Yeah, you'll need 2 lug nuts to properly seat the rotor evenly. Honestly I've never used that method until I owned a tacoma. Also properly beding the brakes too.

 

Did my best to bed the brakes. While it's not NYC, where I live doesn't exactly afford the ability to go from 35-5 & back up a whole bunch of times unless I ran stop signs & red lights or seriously pissing off someone behind me.
Question, from the pics I posted, do the pistons appear to be all in order? Pushed back, or as I call it, seated, correctly?

 

Are you sure the squeak you're hearing is not a u-joint? Does the squeak increase with speed as you move from a dead stop, a lot of times as you increase your speed the "noise" will go away, just hear it at slower speeds,,, I hear a lot of "dry" u joint sqeaks running around town. They'll do that, come and go in noise producing until it gets ready to fall out,

Maybe, but unlikely, cv joint squeak, look for torn boots, usually they'll clunk or pop in a turn.

Need to revise this,,, I guess I'd call a u-joint noise (squeak) more of a chirp than a squeak. Another thing that happens when you get old like myself.

 

No doubt, had people look at me like I was crazy braking every minute going down the street.

 

Missed the question on the pistons on the calipers. If you pushed them back all the way you should be fine. Just use a C clamp and the old pads to push one side in and then use the other. Thats how I have always done it.

 

This started right after the brake job, however any suggestions have been/are appreciated. Once it starts, I hear it from a dead stop up to, say, 35? 40? One of those things that once the rotation gets fast enough, you know the problem is still there, just can't hear it. I grease the joints, but I'll keep an open mind about that. Also, it's definitely a squeak. Not a clunk. I am gonna check the rotor on the passenger side again. Make sure it was seated as good as I got the driver's. funny, since it spins freely, I would' thought putting the lug nuts in at the end was enough to do this. When I did the driver's side yesterday, I could see the difference. I did the passenger's as well, but that's when light was dawning on marble head regarding this, so a double, double check won't hurt. Plus I had found a hair of my deteriorating backplate that possibly was touching the rotor, so felt more like that was the answer & may not have done as good a job as I should have seating the rotor.

 

K. Thank you. Having not dealt with new calipers before, I'd hate to think they were ok & come to find out they were defective to start with. Like I stated, just seems the pistons are seated farther out than on my old ones, even with their hanging on by a thread seals....

 

GL, report back after you tried any and all suggestions.

 

Had a squeeking issue when i reached the speed of 15-20mph or so. It was pretty odd.
Turns out the safety clip was loose (or whatever it's called) once I reseated it went away.

This piece was the root cause for me.



I've also had squeaky brake pads on my mtn bike. If they get dirt oil or grime on them they will squeek.
Need to be very careful not to get chain oil on the brake pad because they will absorb the oil, squeek like a mofo, and get ruined. Learned this the hard way.

 

Soooo.... the clip was fine. I put a little anti-seize on the wear indicators, although I don't think either of them were an issue. There was a spot where the backplate might have been a leettle too close? I attempted to work it, however it doesn't take much to have those in pieces. Anywho, did what I could with it. & seated the rotor with not only two, but three, lugnuts. & then a serious weirdness happened. In order to get the tire back on I had to jack her up a pinch more. I typically go stupidly high so then it's a struggle to get the tire back on, so actually how would I know if this is odd? Dunno. Soooo.... Where was I? Went for a short ride. Same route I went yesterday?, to the store & back. I had heard the squeak on the return trip & this time I did not Now, I am an extremely optimistic person, however after days, well, it's been over a week, of this I am treading lightly. I'll be doing 120 miles tomorrow, so that should seal it. If all is good, my guess is that for whatever reason, seating it properly did the trick. Maybe it was off just enough to make it hit that spot on the backplate? I dunno, but I am so freakin' grateful for all the advice just because, but also because the squeak was driving me even more nuts.... So let's hope this did it & thank you all.... I will let you know how it goes tomorrow....

 

Shit happens, drive safely. Alot of dumb nuts out there...

 

Not sure if it was mentioned but did you clean the "hub" before replacing the rotor? Sometimes brake dust and crap can be there and cause the rotor to not sit level or even. I even use a tiny bit of anti-seize to keep the rotor from permanently joining the hub for the next job.

 

So I'm fairly certain the squeak is gone. The 60 miles to my destination it rained. Made it a little difficult to listen for it. The return trip was windy, but when I got to the home stretch it was calmer, so throughout the 1/2 mile or so of steady lower speeds, traffic lights, corners, etc., I did not hear a peep....

 

Soooooo I had a similar probably and it was the u-joints and cv joint. Crazy I know bc you think it's the brakes but I went an entire year hearing this obnoxious squeak. Changed brake pads, rotors, calipers, rear pads, etc. Finally ran across a thread mentioning the drivetrain.. changed u-joints, cv joint.... silence. Pure, golden... silence.

 

What's the diagnosis if it does?
