Brakes squeaking after changing

[Gary L]

2 weeks ago i took my ST in to have the brakes done, and after 2 days later they started to squeak. I took it back and they re-machine the rotors ,and the same-thing again. After the 3rd time they told me i have to replace my rotors. which was Tuesday. Now after they replace the Rotor and put a new brake pads on. Today the same problem... I'm tired of going back and fort so i call them and say give it a week and see if the squeak goes away

Has anyone have similar problem after changing their brakes:angry:

 

[Frank Marano]

Yes, I changed my front rotors and brakes and they squeak.....they stop the truck fine.

 

[GccST]

Mine do it too. Its really annoying, but they work fine.

 

[Todd Z]

If you use OEM pads they will squeak.... The dealer sells and installs Motorcraft parts, NOT FORD parts, they are different quality.....

Only way to stop the noise is use a carbon or other special pad

ok

My rear brakes squeal all the time, ever since new. My dealer just cleaned them off and sprayed them with something and charged my $69 (under warranty) and they still squeal. On the second visit, he said they were "working as designed" and that all disc brakes squeal.

 

[Gary L]

I know but the first time i had it done at the dealer they didn't squeek and that y i went back to have them do it again. I wont have them do it again:angry:

Brake squealing is caused by the pads vibrating. All pads can squeal and all pads can be stopped from squealing. It has nothing to do with the pad material, but carbon or ceramic brake pads cost more and manufacturered better and tend to be less prone to squealing.



Better qualiity pads will often have a beveled leading and trailing edge to the friction material as well as better isolation pads on the pad backing plates.



I believe most Sport Trac pads squeal because the locating tabs on the pads are not lubed with a high temperature brake grease and that is the main sourse of the pad vibration. The tabs on the pads are designed to slide on the caliper frame and if not lubed, the dry metal to metal contact will create a squealing noise when the pads vibrate.

How comes the "dealer" don't know this Rich

Rich I'm having the same problem as Star36... have you lubed your pads with high temperature grease?? It sounds logical and smart. Is this something that can be done easilly? I wish there was a project that would show us all how... the squealing brakes are such a problem for so many of us. Anyway thanks for the insight.

Star36 and Karl,

I don't know what the dealers know or don't know. Most of the tech's at the dealerships are trained and required to follow Fords repair manuals to the letter. If it doesn't say to lube the tabs on the pads, they won't do it.



That's probably the same reason why Ford technicians will just push your caliper pistons back in without opening the bleed screw which forces that dirty brake fluid back into the ABS system where it can do some very expensive damage.



I suspect that squeaking brakes will bring the vehicles back to the dealer and ultimately bring in more money for the dealership over the life of that vehicle. The dealership wants you to bring the vehicle back for every minor detail onr inconvenience. That's how the service department makes their money!



Most of what I know about fixing vehicles I learned from my own experience or from other experienced mechanics, and none ever worked at a dealership. These guys have learned from may years of experience and yet none of this ever makes it into vehcile manuals and text books.



I have been doing brake work on all my vehicles since about 1965. My first exposure to squeaking brakes was my 1978 Buick Regal. I had the vehicle for 10 years and constantly had problems with squeaking brakes until my late father-in-law showed me how to stop the squeaking. I'm happy to report that I always lube the sliding tabs on the brake pads and the brake shoe contact points on backing plate of drum brakes and have never had another vehicle with squeaking brakes.

Maybe i 'll suggest it to them and see what they have to say:blink:

Many good solutions here, and all combined are true. What will stop your

problem is a combination of a product called "Permatex Anti-Sieze", or as I

so long have heard it referred to as "Silver Lube". It comes in a plastic container/

bottle, approx. 10 oz. size, and is used on such things as spark plug threads,

oxygen sensor threads, and brake caliper sliders and drum brake backing plates

to prevent metal-to-metal contact and seizing of high heat, high stress parts.

It usually has a brush/applicator in the cap for ease of application.

Another product that is used on the brake pad backing plate, specifically, is

"Permatex Anti-Squeal". This product can either be found in a spray can,

(which I do not recommend, for cost and thin application properties), a small

tube, which use to be included with some of the better aftermarket brake pads,

or a brush-type applicator bottle, similar to "Silver Lube".

These two products, along with a proper brake job in the first place, will

undoubtedly cure your problems!

...and people wonder why I do all the maintenance on my vehicles myself.



I do not have brakes that squeal.



Star, if you lived near me I would invite you to my house and I would fix them so they don't squeal...for free. the only catch is you would have to do the labor yourself. You don't learn unless you do it yourself.

I'd love to learn how to do my brakes myself ...after shelling out over 300.+ for Roto and pad not to ,mention making 4 trips back and they're still making noise.

Thanks guys for the Help

 

[Gary L]

Rich i call the dealer and they're saying that they only grease the sliding pins which i have no idea what the hell that is. so is that the samething as the tab

 

[Tom Schindler]

Lubing up the caliper slides just allow the calipers to "float" as they were designed.



The tab is different. If you go by autozone, there is an orangish/pink stuff called Brake Pad Anti Squeal _something_. Pull your caliper off, put a strip on each side of the pad, let dry, then put the caliper back on. Problem solved. I would tell you how to lube up the metal tabs, but unless you know the trick on how to put the pads on, you will go nuts.

I'm defenitly going to learn how to replace my Brake pad so i "ll never have to go thru this

again. I'm not sure how to remove the caliper Brake pad ETC i wish there was a Project on how to Replace brakes

 

[Gary L]

Q" i do get what everyone are stating. like i said in my last post i'd like to learn how to remove the brake pad . The dealer installed the pads and if i attemp to start taking stuff apart and lube and fxxx it up i'm sure they will not warranty the work. My post was to understand how, and why the brake Squeal ...Which base on what my other STer explain i ' do understand how to fix it . the fact in matter the dealer did the work i think they should be the one to correct it. But i'll learn how to do it myself so i dont have to go back to the dealer

But thank u for your input Q

Star36,

If you want to learn how to do a brake job or fix what someone else has messed up, you need to get a manual with good photos and descriptions of the parts and each step.



Then, if you have never done brake work before, I recommend that you have a knowledgable mechanic walk you through each step and show you how to do it and what to look for.



A few years ago, someone did a demo brake job at one of the regional meets and posted photos, however I don't know if they submitted it as a project. Unfortunately, they only removed the old pads and installed new ones and did not do anything to insure there would be no squeaking. They also just pushed the caliper pistons back into the caliper without opening the bleed screw, which is not a good practice anymore, especially on vehicles equiped with ABS.



Since Ford is doing the brake jobs on your vehicle, I would continue to complain about the squeaking until they do somthing about it or refund you money. Then take your truck to an independent mechanic and tell them about your problem and what you were told here about lubing the tabs on the brake pads.



The factory pads come with a stainless steel "Slipper" that should be installed on the back of the pads before they are installed. Some times these "Slipper" pads are already installed on the back of the pads, and sometimes the must be installed befor the pads are installed. Perhaps the Ford Tech failed to install the slippers, although he would be an idiot if that were the case.



I don't know how much luck you will have convincing the Ford Tech to put some high temperature brake grease, or anti=seize compound on the brake pad tabs where they contact the caliper frame, but I'm 99% sure that will cure your problem. assuming they did everything else right.
