electronic meaning there is a sensor that when worn down to a certain point will show up on your display as 'brake service required' type warning. It looks like this.




to the op if you done brakes before on a car in the past, brakes are very easy to do on a BMW. If you have not done brakes before and not mechanically inclined go to a facility to have them done.

Have you tried getting your brakes hot yet?

Getting them hot will burn many of the contaminates away.

I do not generally recommend power washing the brakes as the power washer will tend to wash away the lube in the sliders possibility making a new noise that will require you to remove the pads to lube the sliders.

Have you taken at look at the brake pads to see how much pad is left?

Ok well the discoloration and noise comes from both sides, shall I rule out the sensors then? Will try bedding later tonight

if you are thinking about aftermarket pads later, we carry some that do not squeal and also reduce the amount of brake dust significantly

I had the same issue on my 2004 525i but was due for new pads anyways. I was also advised that I needed to change my rotors (60k miles). I went with R1 Concepts E-line(drilled and slotted) with Posi Quiet ceramic pads. All I can say is daaaamn what a difference overall. First off, I saved like $600 vs going to the dealership/bmw mechanic. Stock rotors and pads are expensive and not sure why as there are lots of aftermarket brands that perform just as well if not better. Once I changed out all rotors and pads, the noise went away, the dust was no more, and the braking power was great. The biggest difference I noticed was dust. I used clean my wheels every other day but now don't have to clean them until the next wash. Also, the drill slotted rotors looks and performs great. Here's a link to R1 concept where I ordered them from. I dealt with James T. (ext 7014) who was great at recommendations and followed up with me after I received the shipment.

I have a squeal that happens when i barely push the accelerator...i can hear a squeal, but only at a certain point of pushing the accelerator. its very annoying when going 20-25 and you have to barely push the accelerator to stay at the speed. anyone know what could cause this? its not squeal due to stopping, even though i do get that as well. just wanted to see if anyone had this problem.
