Default Squeaky Break Pedal

Hey Y'all,

I found the below thread on another F150 forum, from back in 2009. I could not find anything on this forum on this topic. I have this problem with my 05, 4.2L, 2WD, STX.

I'm hoping someone can shed some light on this, perhaps offering an easy, inexpensive and quick fix. Here are the 3 entries I found on the other forum:
-----------------------------------------------------------------------------------------
So when I press and depress the brake pedal, it makes a low sqeak. Not too high pitched but it just sounds like somethings not lubricated. I looked under the dash and its coming from where the metal rod goes through the firewall. Not from the spring/fulcrum (pivot point) of the pedal. Any help?

-----------------------------------------------------------------------------------------
It could be something in the booster, it could be the master cylinder. It might sound like its from the booster but its the MC and it resonates through the booster.

How old is the brake fluid? If its really old you might have some contaminants or whatnot that cause the master cylinder to squeak. Use a turkey baster to suck as much brake fluid out of the reservoir as possible. Then fill it with fresh fluid and bleed the system to move the fresh fluid through the lines.

Use the Ford OE fluid... it has good lubricity and should stop the squeak (the fluid GM uses does not)

If it still squeaks, it is probably the booster. DO NOT USE WD40 or any other oil... the components of the booster (EPDM rubber) do not get along with mineral oils. They will swell up and you will trash your booster. You can try some silicone spray, but use it sparingly.

-----------------------------------------------------------------------------------------

I have not found the problem. I had my very trusted mechanic look at it and he said that it was coming from a bushing (and nobody call my mechanic out on this cause I'm not 100% sure I remember exactly what he told me) that is on the outer portion of the assembly and that in order to get to it, I would pretty much have to completely tear apart and basicly replace the pedal assembly. He said he's seen it on a few Fords and so far no mechanical problems caused by it besides a little annoyance to the driver. He said not to worry about it cause it really wouldnt be worth the cost to replace. Mine actually comes and goes. Sometimes for a month or more at a time I can go with no noise. Then it'll come again for a day. I'm just not going to worry about it though. Good luck.

Thank you. That sounds like the obvious thing for me to try first, especially since I just bought my 05 last month and have no idea when the fluid was changed last, if ever.

Do you have a recommendation of a brand of break fluid, or is that one of those items that is basically adequate under any brand name?

Dont recall the brand just that it was dot3 full synthetic and comes in a yellow bottle, walmart, advance auto, and autozone all carry the same stuff down here. If youre going to make this part of your regular maintenance routine i recommend you pick up an airmotive bleeder, makes the job a breeze and you dont need anyone to pump the break pedal. Also, you will need the big bottle of brake fluid for your truck.
