Thumbs down Brake squeal

Well the front brakes started squealing a pretty good bit and the car just turned over 25k. I thought it might be a bit soon to change the pads, but I do a lot of city driving so I figured I might as well.

So I changed them yesterday, sprayed of everything, checked the rotors (smooth as glass), applied anti squeal to the contact points, checked the clips, etc.

Everything was fine for about 20 minutes, then gradually the squeal started coming back. Now, it's not as often as it was with the old pads, but with the new pads, on the occasions that it does squeal, it's louder.

What's up with that?

Re: Brake squeal

What condition are the rotors in??? Are you sure it is the brakes and could it be the back brakes????

Re: Brake squeal

The squeal is definately from the front, and the rotors are smooth and even all the way around~

The pads are Bendix also.

Since you have PBR's might one of your calipers pistons be stuck??? IS one side squealing only or are both squealing???

Re: Brake squeal

Yes, I had just thought of that. The passenger side is squealing almost exclusively.

And I also wonder, do new pads have a break in time where they will squeal?

But it does seem to be coming from one side only mostly.

Re: Brake squeal

I would pull it out and check the pistons. make sure one is not sticking.

Re: Brake squeal

How would I determine if one is sticking and then how would I "unstick it". Not had to do too much with brakes before~

Also, if it was a piston, would it not pull to one side?

Re: Brake squeal

Several people have also said to give it a week for the new pads to break in because new pads squeal. This was the first time I have ever done brakes myself so I don't have any personal experience to draw from~

Since you have dual pistons compress one and the other should want to move out. Compress on the other one and it should make the other one move out. Do you have a C clamp to do this with????

Re: Brake squeal

Yes, I had to compress them a bit to get the new pads to fit, but when I did that one piston at a time, they would just go in without pushing the other side out...

With newer pads I have never heard or felt squeal. Did you get the pads that are angled chamfers so they help prevent squeal and eliminated dust build up

By angled chamfers, do you mean are the pad surfaces angles at the ends?
If so, no they were flat all the way across~

They were the Bendix life times, supposed to not squeal, have minimal dust, warranty on wear, defects, etc...

There is a equalizing port that runs to both caliper bores to equalize the pressure to make the brakes contact the rotor evenly.

It should not move a lot but it should move a little in the opposite direction.

I did not notice the port, I just compressed one piston at a time and I dont think the one moved out as I compressed the other. :shrugs:

Take them back and get the Bendix Brake Pads: CT-3 They come chambered $55.94 at Advance. These are what I use

Re: Brake squeal

I wonder if when that titanium coating wears off if it will stop squealing.

All I know is I'm sick of the squeal, I went for about a month with it squealing and now it's louder than it was before.

Re: Brake squeal

And I know that's not what the website indicates, but the local Advance stores can't get those ceramic Bendix pads~

Re: Brake squeal

If it is my pistons, I'm going to try bleeding them in the morning and if that doesn't fix it, I'll just take it the shop because I HATE brakes.

Re: Brake squeal

I hate dog poop but ever once in a while you have to shovel it out of your yard. Fix it yourself or lose every ounce of respect from me BY GOD


OK I am just Kidding but brakes are easy

Check for smooth but firm movement of the pistons make sure they move together. Get someone in the car and slowly push on the pedal while the caliper is off the rotor. Push on the one that is moving first to get the other one moving . If they both move it is OK

You can also Chamfer your pads yourself. Shops have been doing it for years before you could buy them that way

Re: Brake squeal

So both should be moving the same amount, got that. I'm really thinking it's pistons~

Why would they be doing that? Should I have compressed both pistons all the way in? I figured they would equalize once I started braking...

one could be corroded inside the caliper and you were able to compress it but it is not moving as freely

Then how would I remove the corrosion. I wouldn't want to spray WD-40 on brake parts...

Re: Brake squeal

Here is an update on what it is doing:

I have just noticed that it does pull to the passenger side, everyonce in a while, I can hear a very small squeel while I am driving that goes away as I accelerate, it pulses occasionally, and now the squeeling is worse than before the new pads~

first do as I said and have someone help you make sure your pistons are working properly. I would chamfer the brake pads and then put it all back together and try it. Do you have access to a bench type belt sander???

Re: Brake squeal

Well I took the calipers off again and checked the pistons. Everything was doing what it should. So I took it to a shop. Apparently the back side of the rotors was badly glazed. So they just resurfaced them and now no more squeaks. w00t!

Re: Brake squeal

my passenger side brake squeels now and again. I also have a tick from the drivers side from a missing or messed up anti rattle clip. I plan to replace the brake system anyway so its no big deal just annoying at times.

Re: Brake squeal

You should upgrade to the Cobra brake system.

Since you have a Cobra and all. It would just be cool to have. Plus it would match.
