I'm surprised by how common it is too. I always thought it was just me and it sorta pissed me off everytime it happened, but knowing that its more common makes me a little more comfortable. I have an 8 year old car, what ya expect. F-bodies.... they are still great!

 

Yeah! Ya just gotta love em !!!

 

ive got a squeak on the left wheel, left turn. Had it before i new pads and after. Car has 79k, did the brakes around 77k.

 

Id have to agree with shimming the calipers, or checking the c-clips. Ive seen two of those when I worked at a Chevy dealer.

 

I had the same thing.
Screeching all the time from the driver's side rear after I put new pads and rotors on both sides. It wasn't SCRREEECHIng before I put the rotors and pads on the car. They don't come from the factory screeching, so it's not a "feature." Right?

I replaced:

Driver's side Rotor x 2 (thinking one got warped immediately)
Driver's side Pads x 2 (thinking different brake composition or whatever)
Caliper Bracket (maybe it's bent)
Caliper Slide Pins, axle grease, make sure the boots are on perfectly,etc.

SCREEEEECCH SCRREEEECH

I tried the blue glue on the pads-no dice.

SCREEEEECCH SCRREEEECH

I opened up the differential punkin and replaced C-clips (they were worn).
New differential gasket, new posi oil and additive.

STILL Screechin. EVEN MORE if that's even possible.

So, I replaced the axles and bearings with that Superior set that Summit had on sale in like April-

Summit Part Number SAG-EV10-5

A second set of new C-Clips, new gasket, posi oil, additive. No shims. The dealer didn't have the shims in stock and I figured I could make them myself.
I put it all back together.

Made CHARP CHARP noise for a day. But then...finally NO SCREECH. Pure silence.

Here's what I learned-
I compared the new axles to the stock before installing them.
1. The stock axles were scuffed and had heat rash where the bearings rode.
2. The grooves on the stock axles where the C-clips ride was almost twice as wide as the new axles. I test fitted a new C-Clip in both. I could probably fit 2 clips on one axle.

Here's what I think happens.
The C-Clip grooves in the axles wear too wide, causing the axles to move in and out of the differential case.
The axles moving in and out trashes the axle bearings.
The axle moving in and out makes the rotor hit the caliper bracket and makes the SCRREEEEECHHING noise. Since there's so much end play, the rotor on the axle is just bouncing off of the caliper bracket, and not grinding metal off.
Screech Bounce Screech Bounce Screech.
On the new axles, the endplay is minimal. The CHARP CHARP sound I heard was the rotor hitting the caliper bracket and grinding metal off because it couldn't bounce back.
As the metal ground off, the SCRREEECH noise disappears. Nice and quiet.

I hope this helps.

Well it looks like it will help ALOT of folks. Thanks, Darrell
