TheRecklessEngineer Posted October 10, 2006 Share Posted October 10, 2006 Ok chaps....this noise is driving me nuts now..... It's a click noise and only occurs when I pull away reasonably quickly after stopping reasonably quickly. The disco will drive for about a meter, maybe a little more and then it goes click, so its not instantanous the moment drive is taken up. Quite a metalic noise and quite loud. It's not a wheel bearing, or UJ, and I cant replicate it by wobbling anything when stationary. Brownie points for the correct answer Oh yeah, '96 disco, TDi, blue....yes the engine does drown it out if I pull away at 4k rpm Quote Link to comment Share on other sites More sharing options...
Fatboy Posted October 10, 2006 Share Posted October 10, 2006 Its the pads in the calipers... Does it have more of a "Clack" than a click? I'm sure that once I've posted this, others will jump on the bandwagon and agree - May even debate click vs clack just to try and glean the brownie point from the rightful owner (just this once! ) Quote Link to comment Share on other sites More sharing options...
freeagent Posted October 10, 2006 Share Posted October 10, 2006 yeah, i agree with him.... i reckon your pads are sticking to the discs.... whip them out, and smear some copaslip on the backs... should work.... Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 10, 2006 Share Posted October 10, 2006 It starts off as a click, but as it gets worse it bcomes a clack, so it rather depends how long it's been doing it for really . Apply copperslip as the Porn King says, also remove any rust from the areas of the caliper that are in contact with the ends of the pads. Les.

TheRecklessEngineer Posted October 10, 2006 Author Share Posted October 10, 2006 No, the beer has gone. Had some studenty types in the back and they drank it all. Got more in the cupboard ready to go in though Ill give the brake pads a bit of greace and see what happens Quote Link to comment Share on other sites More sharing options...
Orgasmic Farmer Posted October 10, 2006 Share Posted October 10, 2006 Does it have ABS? Might it be a solenoid resetting itself or the pump priming itself after braking? My Subaru makes a click a few seconds after pulling away, although to be fair it only does it once in the morning after start up. Worth pursuing if the brake pads fail to deliver the goods.

BogMonster Posted October 10, 2006 Share Posted October 10, 2006 It may also be the guts of the diff talking to you. Both my vehicles do something similar and in both it is the rear diff, its just the carp tolerances that diffs are built to these days, the planetary gears twist slightly under load and emit a metallic "clink". Brake pads also a likely suspect as already said Also could be a slightly loose bolt in the radius arm bushes. Put the handbrake really hard on and rock the vehicle really violently back and forth against the handbrake and see if that makes the noise. If you grease your brakes it may produce a different noise, this one will come from the nut behind the steering wheel and sound like "sheeeeeeiiiiiiii*" Quote Link to comment Share on other sites More sharing options...
Andy Posted October 10, 2006 Share Posted October 10, 2006 If you grease your brakes it may produce a different noise, this one will come from the nut behind the steering wheel and sound like "sheeeeeeiiiiiiii*" my thoughts exactly, just after wonder how large student loans that hes driving a disco? brake pads sound possible or radius arm bushes etc could even be that spare diff in the boot rolling around (yes i did once go looking for exactly that noise) how dumb did i feel?

Tonk Posted October 11, 2006 Share Posted October 11, 2006 whilst you're greasing your brakes just check the calipers aren't loose to Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted October 11, 2006 Share Posted October 11, 2006 I'd bet something in the axle location - there's some clamping friction but if you're <ahem> enthusiastic then you overcome the friction and it moves through its clearance. My Ninety does the same thing. Quote Link to comment Share on other sites More sharing options...
TheRecklessEngineer Posted October 11, 2006 Author Share Posted October 11, 2006 Yup, tis the brake pads sliding around in the calipers. Greased up the backs, but still sticking to the discs. Anything else I can do? Or shall I just replace them? Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 11, 2006 Share Posted October 11, 2006 replace them with something that's a better quality. A set of pads don't cost too much. Some makes squeal when they still have plenty left on them, and some are sometimes not quite big enough. A brake pad should be a snug fit in the caliper body. Les.

SRB60 Posted October 11, 2006 Share Posted October 11, 2006 Yup, tis the brake pads sliding around in the calipers. Greased up the backs, but still sticking to the discs. Anything else I can do? Or shall I just replace them? James Try checking the discs, maybe one or both are warped or there could be a build up of rust on the edges. Also there could be some wear in the caliper causing excess movement of the pads. In the 'past' I have come across a different type of Anti Rattle Spring, it looks like a piece of bent wire - either end of this wire/spring hooks under each pin and the centre hooks over the tab on the pad, this seems to hold the pad more secure. (Has anyone else come across these?). Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 11, 2006 Share Posted October 11, 2006 Two types that I'm aware of - the strip of sprung steel that hooks under both retaining pins and the resulting tension presses on the top of the pad backplate - two per caliper. Then the coil spring, which is really just over each retaining pin, and again two per caliper. I would say that the first was the best at preventing pad rattle. Les.

Live with it because if you try to fix it, it will return after a couple of hundred miles. Quote Link to comment Share on other sites More sharing options...
