Hey guys,
I have a 2009 Ford FG G6 and the front brakes give this high pitch sound when braking.
like there's a spot on how much you step on the brake that it will be loud.
Just replaced the Brake Pads a month ago, the sound seems to be gone after cleaning the brakes, (eg. water or brake cleaner)
could it be just dust? is it common?
Brembo
Brembos are noisy out of the box…give this stuff a try. http://m.supercheapauto.com.au/Product/DynaGrip-Disc-Brake-S…
Might try this.
I had a spray for the disc brakes. But not for pads.
Might be dodgy brakes… Visit your mechanic (who replaced your brakes) and let them know this is happening.
It could be expensive if neglected.
i replaced the brake pads, the brake calipers and rotor are original.
Could be a stone (or other object) lodged between pad and rotor. Had that on a test drive of a Merc A45. The salesperson didn't believe the sound was from their car.
Is it just one side or both?
Can't be any object because I just cleaned the pads and assembled it back. Both front ones.
LOL at the salesperson, where was the sound coming from then? Were they in the car at the same time?
Yep they sure were. Bizarre hey.
First of all, I have friends that I don't know if they are pulling my leg half the time, so take what I am about to tell you with grains of salt. I had the same problem with my Nissan many years ago, and I took it to my mechanic friend to have a look. He took my brake pads off and told me cheap brake pads do that, nothing wrong with them just that they make squeaky sounds when you brake. He then tried to roughen the pads up by rubbing them against the cement driveway and then put it back. The sound did go away, but came back after a while.
That does happen. The pads go smooth.
Try some ear plugs or failing that, turn the stereo up real loud when driving.
Or just avoid using them - problem solved!
Yeah, just coast down hills and turn the engine off when you are pulling into woolies. Pick a park that is a long way from where the entrance is.
Squirt in some oil. That will stop the noise. In fact it will be the only thing that stops.
^ this. A great idea, should try it OP!
Nothing a WD40 cant fix…
Had this problem with my Evo. I was using Ferodo DS2500 pads, which would squeal like hell when coming to a slow stop at the lights/in a carpark.
Did you follow the proper bedding-in procedure for your brakes? From the DBA website:
1) After installing new disc rotors &/or brake pads, perform 8 to 10 slow-downs applying moderate pressure from approximately 50 – 60 Kph without coming to a stop.
2) Make an additional 2 to 3 slow-downs applying heavy pressure from approximately 60 – 70 Kph without coming to a stop.
3) DO NOT DRAG BRAKES!
4) Allow at least 15 minutes for brake system to cool down.
There's not much you can do, it's the nature of sports-oriented pads.
lol +1 to this. we used to say its a feature on Evos that let you know your brakes were still working… almost everyone had that issue, no matter which brand of pads they used. Its a Brembo thingy… Using original pads would help, but it come back
If bedding them in again as per marth6 instructions doesn't fix the noise, increase the speed to 100km/h and try again. If that doesn't work you could chamfer the brake pads with a file.
I had this problem with new brakes on my car. Very very loud squeeking, people would turn to look in carparks, and kept telling me the brakes needed replacing (which they didn't, they were new and fine). Took it back to the mechanic, they 'fixed' it through disc machining and cleaning etc, but was back in just a couple of days - I think all they did was reduce the life of the brakes by thinning the disc and wearing down the pad - don't bother.
They also said its because the new pads don't have asbestos in them, and that I need to keep washing them out with a hose to keep them clean regularly.
Anyway, it took months but it settled down mostly, but not completely. At least now it isn't so bad that dogs howl in the streets when I slow down!
yea im getting this idea that its normal.
dog whisperer car…
The cause of squeaky brakes are the Brake Pads. Since they removed Asbestos from the ingredients of the pads themselves, manufacturers have been on a mission of finding the right "recipe" so the pads don't squeak, nor be too soft/hard, nor wear out too quickly etc. Recently there have been progresses in this area. Suggest you ask manufacturers online, which in their range would they advise to use that have non-squeaky properties. (Get/download an information sheet)
Sounds like a performance problem…keep 'em hot and they will perform normally.. (quietly)..they would only be noisy when not up to 'running' temperature.
I used to work in a brake service, 3rd quarter of the last century, Better Brakes actually had a brake pad exclusively for taxi's (to last longer), when we fitted them to ordinary cars they were too noisy to live with…they squeeled their heads off.
The only solution would be to down grade to a more 'normal' spec.
heavy duty grease works applied to back of pads simple.
Yes, some high temperature copper based grease or any brake pad backing lube will do. Nickel anti seize is fine too. Metal to metal contact coupled with some vibration makes awesome musical instrument. Just visit any mechanic they can do that.
Do not apply any grease or substance on to the surface where the disc and pads meet you digging your own grave.
You shouldn't really care. It's annoying, nothing can be done that will properly solve it. I had it on my car, eventually it went away.
Which brand pads did you use?
