austin Posted March 12, 2011 Share Posted March 12, 2011 Hey guys, just had a first drive since had new discs and pads fitted and I can't help but thinking something's wrong. There's no vibration under braking or otherwise, but now and then I could hear quite loud sound like quick knocking? Hard to describe, but it sort of resembled the sound of a flat tyre i guess. I'm quite worried as I have no clue what that might be - I checked wheel nuts and caliper bolts are tight to manufacture's torque setting. Any advise will be much appreciated, cheers aus P.S. Two yellowstuff pads came with these metal 'nipples' on one side, should these be inner or outer side of caliper? Quote Link to comment Share on other sites More sharing options...

austin Posted March 12, 2011 Author Share Posted March 12, 2011 Was planning to but this sound kinda freaked me out - i dont want a wheel to come off at 70mph lol Quote Link to comment Share on other sites More sharing options...
Zugara Posted March 12, 2011 Share Posted March 12, 2011 I think its the pads chattering within the caliper , slowly reverse and apply brakes, you should hear a "clack" noise if so then thats what the problem is. It is the same on mine. Very annoying but something you learn to l ive with i guess The metal "nipples" are wear indicators, and does not matter if on inside or out.

Haven't had it on my zed but did have it with my old ford puma and my girlfriends punto had the same thing. Think it just depends on what pads are fitted. Puma only did it after a pad change and the punto did it from when it was bought (used) but dealer eventually sorted it! I found it really irritating but don't think its anything to worry about!

austin Posted March 12, 2011 Author Share Posted March 12, 2011 Thanks gents. It may have resolved itself as after driving for a bit today i can no longer hear said sound. On top of that just had MOT done and except for almost illegal rears everything is ace. Think I'll go do Alex's bed-in procedure tonight, however living in London I'll wait until 2-3am so i can find a quiet a-road haha aus Quote Link to comment Share on other sites More sharing options...
