Creaky, squeaky brake pedal (even sitting still)...help me lube it?

Hi all. This is my first post here. I am an avid forum follower but haven't really had a reason to sign up here because we have had very few problems out of my wife's 2008 Taurus Limited and she won't let me modify it, lol.

What it's doing:
So a problem that we are having and have had for several months now is a creaky brake pedal. The brakes are in great shape and work perfect but there is a slow, loud creaking sound when you slowly push the brakes, especially into the last bit of pedal travel. The sound follows the movement of the pedal....push it slow, you get a slow creak. Push it a little faster and the creak gets a little faster. I'm pretty certain it's coming from outside the car so it isn't going to be the brake pedal itself.

What the dealer said:
I took it to the dealer to let them track the noise and lube whatever it is and they didn't fix it. The service guy said it he thought it was coming from both calipers and recommended that I have the rotors machined and grease the slide pins. The noise occurs regardless of whether the car is moving and the brakes work fine so I don't see any benefit in machining the rotors. They apparently did not see fit to grease the slide pins but instead told me to do it.


What I need help with:
So I am going to give it my best shot. Just looking for recommendations.
* Does this sound like the pins are the likely culprit?
* What type of lube should I use? I have read that I should use a lithium based lube and I also read that an anti-seize compound works well.
* And most importantly, any special tips on what I have to remove and how-to in order to inspect and grease the pins?

Thanks ahead of time!

Did they check out the master cylinder?

Pins are easy to grease. Usually you just end up with a stuck caliper when the grease goes bye bye. Use cv joint grease, or some other high temperature grease. Just have to remove the caliper and then the caliper pins. Careful not to damage the brake like.

I also agree, have them check the master cylinder as well as the brake booster. My sable had this problem years ago (it's a 2000). I don't remember what the fix was. I've heard from others on this site that it was the master cylinder. I'm going to go through my service records later and see if I can find it.

First thing I would do is take the front calipers off and grease the slide pins. Wipe them clean, if they are rusty clean the rust off with some sandpaper/emry cloth then apply some anti-seize to them. The brakes in my Freestar did this till I had them replaced and made sure they greased it all up at the dealer(company pays for that car so it goes to a dealer for repairs).

No, the dealer didn't check the master cylinder or anything else to my knowledge. He said that with it on the lift they could press the pedal and isolate the noise to the two front calipers.

What's kinda aggravating is he called me and said we think you need to turn the rotors and grease the caliper slide pins....would you like me to turn the rotors? For $112 and considering I do not think there is anything wrong with the rotors, I think not. He said, okay it's ready then. It was almost like he didn't want to mess with greasing the slide pins which I believe will fix the problem. I'm a semi-shadetree mechanic but I have never messed with the brakes on this car and I don't know if I even have the proper tools to do it.

Three years down the road and my taurus-x is having the same issue your Taurus was having back in the day. My pins are plenty well greased. The noise actually went away when I replaced the brake pads. It is back now, though the pads are at about 80%, nowhere near worn out. Pressing the brake pedal seems to rock/roll the caliper around a bit as the brake pads tighten up on the rotor. I cleaned the shims, even glued them to the caliper thinking the springs were noisy. No better. Darn thing still groans when I push on the brakes whether it is rolling or not. Brakes work great, just sound awful.

My 08 has been doing this for the past 5-6 months. I lubed the guide pins myself. After the noise returned a few days later I took it to the dealer. They said lube the pins, I told them I already did then they recommended changing the pads and rotors to Motorcraft parts instead. I told them no thanks, the stuff that is on there is less than a year old and not a junk brand. So the pins were lubed again, another week passes with creaky sound, installed new guide pins and the sound still returned after a day or so.

I tracked the noise down to the actual piston or pistons in the caliper itself. Mine still has a warranty on it but Ford will not replace them unless they have already failed. I will most likely just replace the calipers themselves here soon cause it's gotten pretty damn annoying.

Did you try putting a layer of grease on the back of the pads? Even rubber undercoating or plastic dip would help.
