New front pads fitted, now there is a rattle

[ally0000]

Hi All,

I have just had new front brake pads fitted by my local (non-Audi) garage, I've used them quite a few times and them seem OK. This was last week and I noticed on Sunday when I was driving over cobbles with the window down that there is a loud rattling noise coming from the front end.

I called the garage and it was back in there on Thursday and they said the pads have not worn into the disks yet and I need to drive the car for a couple of weeks and to brake harder. I asked them what was actually rattling and he said that it was the brake pad rattling in the caliper (I think he said the caliper, can't remember exactly). To be honest this sounds a little dodgy, can't imagine why pads that are not 'bedded in' should rattle.

I mentioned this issue to a guy at work who tinkers with cars and he said that pad should NOT rattle and should no be loose in there, he said that if it was loose then the clips that hold the pads are worn and are not 'springy' enough. He said that if the disks are worn then they should have had them replaced too.

Not being mechanically minded I wanted to ask you guys what your take on this is, I think the people at the garage are not telling me everything. I am considering going to Kwik-fit this weekend and just asking them to have a look at my 'new rattle at the front end'.

Thanks a lot,

Ally

Check the spring clip on the calliper is clipped in (or even there)



Check the brake splash shield thingummy bob isn't rattling against the dics/wheel - if it is, bend it back a bit.

Thanks for the picture, Ihave printed it and will check after work, I forgot to mention that when I press the brakes the rattling stops.

Sounds like the clip to me - it's a fairly common issue.

Could be the calliper pins, could be that they didn't use any anti-squeak, etc

[ally0000]

Thanks Sam, is the anti-squeak an Audi only thing or is that common accross most makes?

[Sam]

It's a common product, usually supplied with new pads.

Anti-Squeal, Anti-Squeak, brake paste, etc

I’m having the same problem on my a6 c7 . Just had mintex discs and pads fitted . They rattle over every speed hump and they slip in reverse. Has the mechanic back who took the pads out . He bent the retaining clips back to make it a tighter fit . It was better for a couple of weeks but the rattle and slipping is back again . Can the OP tell me which brand of pads worked for him . We’re they genuine Audi parts ? Thanks

try Pagid from EuroCarParts, they are OEM

Some of them , if not all come with sliders to fit

What you may find with pads, is that they put a real extra thick paint on the metal; causing them to stick in the sliders. I have had to buff them down on a grinder , just enough to slide freely but not be loose

A wee dab of Copper grease as well helps

Also make sure you check in which pad goes to piston


I get around 40-45,000 miles in my A6 with the Pagids, towing a 1,800 kg horsebox as well

I had a similar issue. Bought my pads from euro car parts. Turns out there are 2 different sizes because some of the same model has bigger disks. Mine are the bigger ones. I knew something was wrong when I noticed the new ones didn't have the bits for the retainer clip to go in. You may need to measure your disk diameter as the garage will just use your number plate and may assume all results are the same.
