2008 E70 Brake Squeak

[Marcool]

My 08 X5 now has 3000KM on it ( too bad I don't drive it a lot). But recently I was so pissed off by the brake squeak. It happens when I drive slowly or at slow acceleration from a stop sign and I could'nt tell it's from the front or rear (or both). But it disappears when I hit the brake. This annoying squeak gets worse when it's wet or snowing and makes my X5 sounds like a ice cream truck.

I got an appointment with my dealer but I will have to wait two weeks. Does anyone here experienced the similar problem or any suggetion about the cause? Thanks.

Disc brakes are not that complicated. The way the brake caliper holds your inner and outer brake pads is that:
Inner: held on by the piston
Outer: freely hanging on to the caliper bracket -- that's the source of the squeak. when it's loose, it lightly rubs your rotor (squeaks) - until you apply brakes (firmly grabbing on the roter, no squeaks)
It's a simple fix, a dab of the sticky goo or spray on the back side of the brake pad so it's not so loose.

It can be done anywhere, but does require to take the wheel off and the caliper off to get to that exterior brake pad.

mine has about 3500kms on it. before it was squeaking when brakes gently applied all the time. now it's doing it less. eventually it will stop. just give it time.

I think we have different problems. Yours is squeak when gentlely applying the brake. So the squeak is expected to disappear after the "brake-in" period. Mine is squeak when driving slowly (gone when apply brake more than gently). It looks like the pads fail to be released at low speed.

No. It's turned off.

My guess is you've got some crap stuck in the pad. You may want to use a pressure washer and give it a good blast (each wheel). Sometimes the sand/salt crap on our roads will get lodged into the pad.

btw, how come your 2008 only has 3000kms?

Exactly same problem here with my Aug'08 X5 with 4000 miles. Went to dealer (Chicagoland area) and told me that they didn't find anything (what....????) wrong with brakes. Told me that it might be snow/salt issues but not satisfied with their answer. I don't know what they did, but after the visit, I haven't heard the noise for two weeks and then started again...

My 10 year Honda and 4 year Lexus brakes never made any noise in any weather conditions, why is this so called "HIGH END" luxary cannot handle?
