Strange Braking Noise

Hi All, wonder if you can help. We have an 08 R56 Mini One 1.4, this has recently started to make a strange noise when braking.

The noise is from the Rear.

The best way I can describe the noise is its as if you are driving over rumble strips, this only happens when braking from around 20mph and gives a physical feel as though you are actually going over bumps aswell as the noise.

First thought was an egg in the tyre, but it doesn't make the noise/feel all the time only under braking, then I thought Brake Pads, it does grind a little but not all the time, are the wear indicators designed to make this feel/noise.

Thanks in advance,
Andy

I have a slight knocking noise that only seems to occur at sub 20mph speeds and sometimes when under braking too.

After spending a while underneath with a torch, I think its the rear anti roll bar bushes. At first look, the ones fitted at the moment look ok. However after buying some new ones from the main dealer for £8 a pair, if you compare the old and new ones, the old are definitely well worn and even the smallest amount of wear can cause a fair bit of play. I'm hoping that resolves my issue. May be a similar issue for you?

Warped Discs?????

Is there any chance the discs are a little warped? (how many miles ya got) I agree with another reply you got, make sure the pads are Mini pads or up to Mini specs/requirements & stats. The great pad and disc quality are one of the reasons why a Mini can brake so good and offer such great feed back to the driver via the pedal! Hope ya get it figured out... :nice:

Noises are hard or not.I would expect a brake issue to squeak not really noise or may be break pads are lose that's why the noise is emitted or may be its emitted in the tire..
