I'll buy a beer who can help me solve this:

...My front brake pads(drivers side specially) makes alot of squeaking when breaking to a stop.
Very high pitched noise.. Its embarrassing now,everyone around hears me breaking :"Hey there's Alex"

I'm surprised no one has pointed out, yet..

If removing this annoying squeal is the sole intention, and you are prepared to accomodate a "little inconvenience" there is a straightforward procedure that will pretty much guarantee silence from them..

An even and liberal coating of MS3 grease to both sides of the front disc rotors and the friction surface of the pads should alleviate the squeaking, at least for long enough that this annoyance will be rendered irrelevant.

Hth.

P.S. I'll have a pint of Theakstones Old Peculiar thanks.!

I’ve never done any of that !
I usually drive steady with light braking for the first 200 miles or so, never hard braking with new pads.

Tbh neither have i. I just googled the best way to bed them in & that`s what appeared. Must remember to try it next time round. I had something similar with my E46 330i but i treated new discs & pads all round really gently for a few weeks. When stopping from say walking pace the brakes made a graunching? sound which was not nice & bloomin annoying. It`s stopped now.

Funnily I had a e46 convertible 325i, I fitted cheap Euro Car Parts pads and it squealed like mad, I changed to minted and it went away instantly. Nothing to do with callipers or shims, never had the problem before that or after, and I’ve changed lots and lots of pads.

I remember years ago seeing anti-squeal shims on the shelves of the local autoparts shop. A quick google shows that you can still get them, they should be cheap enough that it'd be worth a punt:

Rotate the left hand radio knob in a clockwise direction until the noise disappears

With that advice i cant believe you`ve never owned a E46! I`ve been doing this for 14 years

How do you break in new brake pads and discs?

How Do I Break In My New Brake Pads and Rotors?

1. Find an empty parking lot or street. ...
2. Engage hard braking at 40mph. ...
3. Go 50mph and jam the brakes until ABS engages. ...
4. Repeat step #3 four more times. ...
5. Reach 65mph, then slow the car down to 15mph. ...
6. Let your brakes rest for 20 minutes. ...
7. Conclusion. ...

There is absolutely no need for this if correctly fitting good quality brake pads into calipers that are in good order.

Yes, performance stuff and AMG brakes often need a bedding in procedure as they will glaze or not fully bed in for a long time, if not followed.

That said, that procedure is too agressive, and will cause glazing and pad transfer on new brakes.

1. Brake gently from 20mph down
2. Brake slightly more firmly from 40mph down
3. Brake more formily from 60 mph down

Thats basically it.

Thats pretty much how ive bedded them in, in the past. Never done it this other way just wondered if i`d got it wrong

Get rid of the pads and fit merc genuine.

Pint of IPA.

If it makes you feel any better, mine do exactly the same, and i have done exactly the same as you, I am now on Brembo discs and pads (after ditching the pagid rubbish), and yes they still squeal.
I have tried everything you have.

So now I ignore it. the brakes work really well, they are just annoying.

Nice to know I'm not on the same boat..last week took the pads out (again) and put loads of anti squeal past on the back,i emptied the full package.
Still squeal but it reduced the noise by 30%.. its a start.
After an intense online reachearch by me it looks it's the calipers design the main problem. Specially the ones like mine with dual piston.
The pistons must push the pad uniformely,if not ,one side of the pad is pressed more than the other and squeals.
Other thing i found out brembo pads squeal..loads of internet forums relating to that.
Its one thing I'm gonna have to live with it until i pay the finance and sell the car ..

Quiet on mine.

 

[unclebuck]

Had this on mine for the past month or so.. didnt have time to sort it out straight away.

Same dual piston caliper as yours

1. Jack up car on offending side
2. Grab each side of wheel and pull back and fore, see if there is even the tinyest play or click that you can feel, it doesn't have to be much.
3. order new wheel bearing and fit
4. squeeking gone from brake.

My bearing had gone in mine and that tiny bit of play meant the brake squealed like mad every time i braked. The commute to work was long and back and for I had to wait for the new bearing and hub kit to come in and then fit it.

The play when i grabbed each side of the wheel and pulled pack and fore each side was tiny, mere millimeters but enough to cause the issue

If this is what the issue turns out to be.. I dont drink alcohol but a ginger ale always hits the spot.

Thanks I'll have a look.
Someone also mentioned me wheel bearing but i never though that might be the cause

The noise is coming from the brake shims, well actually from the brake shims not doing their job of dampening brake system component vibrations that cause the noise in the first place. Are the shims in good condition? Were the shims replaced? are they fitted correctly? Did you need/ use a paste on the backing plate of the pads?

All brake pad sets I have bought have come with the shims ( Some like the Bendix Euro + give you shims, wear sensors and the bolt hardware)

As it happens I used Textar pads and Zimmerman discs and have no noise. These are directional pads ( took my a while to work out the diagrams bloody Germans over-engineering ..) and they specifically say no copper paste but to use *their* specially formulated paste ( bloody Germans over-engineering). Of course I put no paste on at all because I opened the box and only knew of Textar's "special" paste after the wheels pads and rotors were already off.....
