New brakes are sqeeking LOUND

[A13ART]

so i bought all new rotors and pads and i bedded them in and drove like 150 miles at least on them and hey are still sqeeking extremly lound when i break and i brought it back and the guy told me he are agresiv pads and will do that if this is true wish i was in formed

[phEight]

some pads are squeaky... it would help if you mentioned what kind of pads you had installed.. and there is also a spray you can get to spray on your pads to avoid squeaking.. im sure others will chime in and be a bit more specific about it

[Carlitos]

spray half a can of WD-40 on each rotor, make sure to spray on the pads too!

[A13ART]

so take off the prakes and sray them snd i blive i got mintech pads

[BNZ TOY]

Give it a week of regular driving.

[A13ART]

well i have been using the padslonger then a week its so bad i was thinking of replacing them and i just bought theses what a waste its funny in a way everyine rools up there windows by me

[gunde]

You can try sanding or filing the front of the pad ( from the rotation point of view) to give it a wedge shape. Basically just file the corner down so you get 3 faces instead of 2.It helped alot on my car.
I was also thinking of buying different pads they were so noisy. Now it is "almost" silent

[NightRider]

Lound??? What does this word mean? hahahaha, sorry for bustin your balls, i had to

[pondside36]

Did you use brake quit on the back of the pads... if not this could be your problem... just did my rears and not a peep with Hawk Ceramics

2nd on the pad quiet paste. If you did, re-bed them again.

How did you bed them?

[old guy]

This is the best stuff I have found. Used it for years and never a squeal.

[quattrotman]

spray half a can of WD-40 on each rotor, make sure to spray on the pads too!

I hope your kidding.

well i had them done a genasis racing development and i dont think they did the disc brake quiter and then when i went back he said he could but it goes away after like a hours of braking so i said not to worry about it but what is a good way to bed the brakes in so i can re bed them

[wolfdog]

I hope your kidding.

Goes away after hours of braking? They pretty much stay on the back of the pads till they wear out and then some. I've never seen disc quiet evaporate or disappear.

I'd take the brake pads off yourself and just apply disc quiet.

Not sure how it is on our cars cause i haven't done brake work on my car yet, but i know most cars have shims attached to the back of the brake pad which i believe has some sort of silencing effect. When my brother was replacing pads the first time he re-used the stock shim and all was quiet...2nd time, same brand pads, and he decided to ditch the shims, the brakes started to squeak a bit.

Correct me if I'm wrong on that.

I'm just saying, if there were shims on your old pads, you should put them back on the new pads as well.

[gdawg'05a4]

I've done brake pads on Audis before and AFAIK, there are no shims. The pads just rest against the caliper. The metal backing of the pads onto the metal caliper, nothing in-between which is why the disc quiet is needed.

[diagnosticator]

Most pad sets are now provided with vibration damping shims that fit between the back of the pad and the caliper. If shims are present, additional Brake Quite, by itself, won't help much.
Another aspect that is often involved, is that the pad backing plates wear groves in the caliper where the pad backing plate lower ends touch the machined pad support surfaces of the calipers. The grooved pad supports, prevent the pads from sliding freely on the caliper pad support. This will cause the pads to hang up more or less, and the hang up will cause uneven pressure on the pads against the rotors. This is frequently the cause of squealing brakes. Fileing or better, machining the caliper pad supports to eliminate the groves, is an important part of relining brakes, and will help prevent the vibrations of the pads that cause the squealing noise. There is a limit to how much material can be filed or machined away without wrecking the calipers obviously. 1-2 mm is OK, but more than 2 mm would mean welding and re machining or replacement of the calipers. Stainless steel shims at the lower and upper pad supports is also a pr oven fix for wear groves in the calipers, but is a custom fit solution.
Finally, lubrication of the ends of the pad backing plates and adjacent pad support surfaces, using synthetic high temp disk brake caliper grease, is also highly effective helping to prevent brake noise, but is only helpful if the calipers have nil or no backing plate wear groves.

i think i am gan call the place up maybe sell theses pads and get some other ones cuz i dont track enough to use these

[cantfaded1s]

I actually had my rotors and pads replaced a couple of months ago and had the same problem with the loud squeeking (brembo rotors and mintex pads). I was annoyed for the longest time but figured they would subside on their own after breaking them in. That didn't happen, but eventually after a thousand miles or so they don't squeek anymore. Not sure if you want to go the route that I took as it did annoy the shit out of me for a long time, but it might go away after some time like mine did.
