Is it happening while you press on the brakes? Like pumping them?

Only when I press the brakes

If I release the brakes

Noise gone

Do you think my rotors are warped ?

And I am not messing with the brakes like pumping them lol


That is just me stepping on the brakes like maybe 20 %

This is just a guess. Could be your caliper making the noise. You press on it and it makes a noise. You release it and it stops. Just a guess.

I have not done breaks on my bmw yet but I know some use brake grease where the pads come in contact with the caliper or caliper pistons.

It is weird it went away and came back.

I swapped out the rotors from right to left left to right to see if the sound will now go o the opposite side that didn't help at all

Same exact sound same side

Rear driver side

Anyone have a clue what this can be?????

Is the backing plate the rotors bolt to clean and flat? (Use wire brush) If the rotor doesn't sit flat, it will make noise. Stock brakes? (single piston caliper) If the pin isn't greased and the caliper won't slide it can make noise.

So I took apart the whole thing greased up the pins on the pad and on the calipers to make sure it has grease to slide the noise went away

Then a week later noise happen again...

I just went and bought new pads going to slap them on and see if that helps

This noise is so fucking annoying

is pissing me off

Is a stock brake system

The single piston..


I mean it seems to be clean but I get Ima give that a try now

So what exactly do I clean before I pick up the pads at 2:30



Or what do I need to scrub ?

The backing plate where the rotor sits ?

Yes. If there is crap there, the rotor won't sit flat and it will wobble like it is warped.

So the hub

The wheel hub where the rotor sits and bolts down

I just cleaned all of that now

I almost feel like this nose is coming from the E brake

Does the ebrake move or works aswell when you apply the brakes while driving ?
