New US Brake Squeak SIB for M5/M6
BMW USA have released "SIB 34 06 14" to deal with brake squeak on non-carbon equipped M5/M6.
Dealer will check the "balance weights" on the brake pads and replace the pads should the weights be loose. If weights ok pads and discs will be checked for other faults including thermal stress.

Interesting. I can see smiles on a lot of M5 owners faces now. Hope this works. Now if every other sports car mfg would do the same.

This could be simply to placate the customer.
Though, hopefully it does work and doesn't reduce braking performance.

I've never heard of balance weights for brake pads. Is there a picture of the BMW "balance weights" on their brake pads? I have used pads and new pads in the garage with a BMW part number and there is no sign of any added weights. Of course my never having heard of them doesn't mean they don't exist, but I'd love to see what BMW identifies as a "balance weight" for a brake pad. Perhaps their language in the SIB doesn't do well from the German to English?

At the ends of the pads you can clearly see the shiny metal weights sticking out. When I mounted the brakes the first time I wanted to take them of, but then I thought ..... may be not. Last edited by MyF15+F85; 01-03-2015 at 06:56 AM.. Reason: more info |

Pads used on Brembo type calipers have a balance weight fitted on each corner. These may have come loose on certain cars causing vibrations that make the noise. They are also sometimes called "Vibration absorbers" The dealer will remove the pads and check the weights as a first step under the SIB

Yes, just quote the SIB number "SIB 34 06 14" to any BMW USA dealer.

Even the 1976 E12 5 Series has them Most current BMW sensors are 2 phase sensors, allowing the onboard computer to estimate the pad life remaining more accurately.

My service manager told me that the electronic pad wear sensors will indicate pad replacement at about 3mm of pad thickness. |
