Squeal Durning Breaking.

[Beebe]

My wife has a 2005 Suburban 1500 4x4 with a 5.3L. What is really starting to bother me is a squealling sound while breaking. I know some of you just rolled your eyes and were thinking "wear indicators" but the breaks are new. I replaced the rear rotors and pads about 4 months ago, and the fronts 2 months ago. It's really odd it sounds like a wear indicator but it can't be. Please help.

Thanks,

Beebe

Might be a Stuck Pig up in the wheel wells?

 

Seriously, Are the anti rattle clips all in good shape and the rotors true? Could be as simple as dust or dirt. Give them a good wash see if it helps. I find that aftera long trip especially towing mine start to sqeek and after a good cleaning sound is gone.

It happens depends on the pads sometimes they just squeak, a good cleaning will help.

 

How loud is the squeal?? Because wear tabs are usually very loud.

Plus if you look at the pads, you'd be able to see physically if the wear tabs could be touching or not.

could be the film of shit on new pads wearing off

this is what a shop near me uses all the time. he told me its actually a metal spray and it fills in any little holes or anything like that. even on brand new brakes he puts this on.

I have found in the past 2 different things. I always use high temp brake grease on the pads and any contact points. Also, make sure your rotors aren't glazed or (in the case of GM trucks) pitted on the back side. If they are pitted they will always either chatter or squeak. I have gone to the trouble of using sandpaper or use a right angle die grinder with a 3M ro-loc to knock the glaze off of a rotor. The pads need to have an etched surface in order to bed properly. If not, chances are, they will squeak.

First of all I hope you don't mean on the pad surface for the grease! Because that wouldn't be right!

Thanks. I will take a look at them this weekend.

Well, if you know your sphincter from a hole in the ground, you would know that you don't grease the pad surface. The high temp brake grease (permatex is my choice) goes on the back of the pad (contacting the caliper and piston) and any contact point that touches the caliper. Which includes alignment pins, clips or bolts (for floating calipers). If anyone who reads this, thinks they would grease the pad surface, then you should be paying a mechanic to do your work...

Beebe,

 

Without hearing your truck braking/squealing, I wonder if you have the same problem as I do.

 

Several months ago, I had an issue with my 2008 Silverado where I'd get a squeak at the final last feet of a stop (moving very slowly at that point). I posted the question on here but didn't get many similar responses. Some said it was the rear drums and I should take some fine-grit sandpaper to the them. Some said to check the wear indicators on the front pads and grease the slide pins. After pulling the front and rear tires/brakes and checking these things, my problem has not gone away. There's still plenty of life left on the front pads and rear shoes. Now, here's something to check however! I just took my truck in (38,000 miles) to the GM dealer and had them replace the left rear axle seal. When I had the rear tire and drum off, everything seemed a little wet or damp compared to what I was used to seeing. The work was covered under warranty and I'm hoping my squeak clears up once the pads dry themselves off!

Gentlemen,

 

Disk brakes are inherently noisier than drums. They do manage to keep them quiet these days but they are succeptible to contamination from anything on the road.

 

A little rust, water, salt, a dash of road oil and the music starts.

 

Cleaning will help, try a different brand of pad. Factory pads seem quiet and I use Raybestos with only occasional noise.

 

Worst part of the noise seems to be that your passenger thinks you drive junk.
